Description

Technical Field

[0001] This invention relates to the field of mattress manufacturing technology, and in particular to a multi-point pre-compression installation device for mattress spring packs. Background Technology

[0002] Spring mattresses, with their excellent support and comfort, have become one of the most mainstream bedding products in modern home life. Among them, pocket springs are widely used in the manufacturing of mid-to-high-end mattresses due to their advantages such as independent operation of each spring, strong anti-interference, and conforming to the curves of the human body. In the production process of pocket springs, compressing the springs and then packing them into non-woven fabric bags is a core process. The quality of this process directly determines the stability of the springs within the bag, the uniformity of the bag's wrapping, and the final product's lifespan.

[0003] In existing mattress spring assembly technology, traditional methods mostly involve manual or semi-mechanical processes for spring compression and bagging. In manual operation, operators need to manually compress the spring to a certain height before inserting it into a cloth bag. This method is not only labor-intensive and inefficient, but also prone to spring misalignment or twisting after compression due to the instability of manual force application, resulting in uneven bagging and affecting the appearance and quality of the finished product. Furthermore, prolonged repetitive labor can easily cause muscle strain for operators, posing occupational health risks.

[0004] To address the aforementioned issues, some companies have begun using automated or semi-automated equipment for spring preloading. Existing preloading devices typically employ a simple opposing pressure plate structure, where cylinders or hydraulic cylinders drive the pressure plates to move in opposite directions, compressing the spring to a predetermined height. However, these devices have several shortcomings in practical applications: First, it has poor adaptability. Mattress springs come in various specifications, including differences in diameter, height, and elasticity coefficient. However, traditional pressure plate devices have a limited range of adjustable pressing gaps, and the adjustment method is cumbersome, making it difficult to adapt to the need for rapid switching between different spring specifications. When producing mattresses of various specifications, frequent equipment adjustments significantly reduce production efficiency.

[0005] Secondly, the pressing process can easily damage the spring. Traditional devices use a flat pressure plate to directly press the two ends of the spring. This results in a single point of force application and a large force-bearing area, which can easily lead to irreversible plastic deformation at the spring ends, affecting the spring's mechanical properties and fatigue life. This is especially true for springs with special end structures, such as springs with constricted ends or support rings. Traditional pressing methods can easily damage the end structures, causing the spring to lose its proper support effect during subsequent use.

[0006] Secondly, the precision of the pressing force control is insufficient. Existing devices mostly use pneumatic or ordinary hydraulic drives, and the adjustment of the pressing force relies on the coarse control of the air source pressure or hydraulic valve, making it difficult to achieve fine adjustment of the pressing force. For springs with different elastic coefficients, excessive pressing force may damage the spring, while insufficient pressing force cannot compress the spring to the required size for bagging, resulting in difficulty in bagging or loosening of the bag.

[0007] Furthermore, existing equipment has shortcomings in maintaining the spring's shape after compression. Traditional compression methods often compress the spring to a flat state, completely destroying the natural shape of both ends. This results in the spring pouches failing to maintain a full and neat shape after assembly, reducing the product's aesthetics and market competitiveness. Simultaneously, the springs are prone to slippage during the compression process, causing equipment malfunctions or safety hazards.

[0008] The present invention aims to solve the technical problems existing in the prior art. To this end, a multi-point pre-compression installation device for mattress spring packs is proposed. Summary of the Invention

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. It achieves efficient and precise pre-compression, improving the convenience of subsequent bagging operations: Two sets of symmetrically arranged adjusting and pressing mechanisms can quickly pre-press the mattress springs, compressing and fixing the spring shape, which facilitates the subsequent spring bagging operation and significantly improves production efficiency.

[0013] 2. Possesses wide applicability and flexible adjustment capabilities: Reverse drive module: By using drive studs with opposite rotation directions at both ends of the drive component, two sets of pressing mechanisms can move synchronously in opposite directions through a single power source, precisely adjusting the distance between them to accommodate mattress springs of different sizes.

[0014] Position adjustment module: The position of the pressing module inside the spring can be further fine-tuned by adjusting the telescopic column. In conjunction with the steering drive shaft, the pressing angle can be adjusted to ensure that the pressing module can be accurately inserted and act on the ideal position of the spring, thus enhancing the compatibility of the device with springs of different specifications.

[0015] 3.

[0016] Multi-point uniform pressing: The pressing module uses multiple pressing telescopic columns arranged tangentially, which can apply force evenly from the inside of the spring to the outside, achieving multi-point pre-compression. This method avoids the spring deformation or damage that may be caused by traditional pressing, and can retain part of the shape of the two ends of the spring after pressing, which is more conducive to maintaining a full and regular shape after the spring bag is packaged.

[0017] Anti-slip design: The anti-slip ball at the outer end of the pressing telescopic column can effectively prevent the spring from slipping off during the pressing process, ensuring the continuity and safety of the operation.

[0018] 4. Precise adjustment of pressure and sensitive response: The adaptive pressing module employs a unique hydraulic linkage design.

The adaptive pressing module is inserted into the mattress spring, and then the spacing between the internal thread guide cylinders 13 is adjusted in the opposite direction to press the mattress spring. The distance between the adjustable mounting plate 18 and the displacement mounting plate 6 can be adjusted by adjusting the distance telescopic column 17, thereby further adjusting the position of the adaptation compression module in the mattress spring.

[0038] Depending on the size of the mattress springs to be pressed, an external tool is inserted into the drive hexagonal sleeve 32 to rotate the adjusting stud 31. The position of the adjusting stud 31 is adjusted in conjunction with the internal threaded cylinder 30. With the cooperation of the transmission shaft 40 and the transmission bearing sleeve 41, the positions of the narrow-diameter piston 29, the synchronous transmission column 33 and the wide-diameter piston 34 are adjusted simultaneously.
