Description

Technical Field

[0001] The present invention relates to the field of mattress processing, and particularly to a spring mattress edge - pasting system. Background Art

[0002] A mattress is an item placed between a human body and a bed to ensure that consumers can obtain healthy and comfortable sleep. There are various mattress materials, and mattresses made of different materials can bring different sleep effects. A spring mattress is a mattress composed of springs and is widely used because of its good elasticity, load - bearing capacity, and breathability. A spring mattress usually needs to be edge - locked to connect the edge steel around the four sides of the spring mattress, so as to improve the hardness of the four sides of the spring mattress and ensure the overall rigidity of the spring mattress.

[0003] The rubber - edged sponge is glued to the side of the spring core to reinforce the sponge on both sides of the spring core, and at the same time increases the integrity of the mattress and the comfort of the mattress side. When the spring core of some spring soft mattresses is not reinforced with edge steel, the rubber - edged sponge also plays the role of edge - steel reinforcement.

[0004] Currently, when pasting the edge of the spring core, the traditional method is to paste the edge manually. In this way, first, the top sponge and the four sides of the spring core need to be pasted manually, then the spring core is turned over, and then the bottom surface of the spring core is pasted. The whole process consumes a large amount of manpower and material resources. Especially when turning over the spring core, the cooperation of multiple personnel is often required to achieve it, which is very troublesome and the work efficiency is not high.

[0056] The second edge-laminating unit 4 is used to laminate the second semi-finished product and the top cotton to form a finished spring mattress.

[0057] Specifically, as Figure 10 It can be seen from the schematic diagram shown that the second edge-laminating unit 4 includes a second edge-laminating bracket. An upper and lower distributed laminating conveyor belt 43 and a pressing conveyor belt 42 are installed on the second edge-laminating bracket. A gap for the passage of the finished spring mattress is left between the laminating conveyor belt 43 and the pressing conveyor belt 42.

Both sides of the pressing conveyor belt 42 are installed on the rotating frames 41 through the cooperation of the pressing cylinder, and approach or move away from the laminating conveyor belt 43 under the drive of the pressing cylinder. Through the design of the upper and lower distributed laminating conveyor belt 43 and the pressing conveyor belt 42, and then cooperating with the actions of the vacuum suction cups and the pressing cylinder, the turnover of the top surface is realized, so that the top surface can be smoothly pressed on the upper end surface of the second semi-finished product subsequently.

[0059] The blanking unit 5 is used for the blanking and conveying of the laminated spring mattress.

[0060] Specifically, the blanking unit 5 includes a blanking conveyor belt 51, which is installed on a blanking conveyor support and driven by a blanking motor installed on the blanking conveyor support to work, and the conveying direction of the blanking conveyor belt 51 is consistent with the first direction.

[0061] Working principle: When laminating a spring mattress, first, a piece of cotton is grabbed from the bottom / top cotton feeding platform 12 by the material grabbing mechanism and placed on the feeding conveyor belt 11 as the bottom cotton. Then, the feeding conveyor belt 11 conveys the bottom cotton to the glue spraying conveyor belt 21, and the first glue spraying nozzle and the second glue spraying nozzles 25 spray glue on the upper surface of the bottom cotton. The first moving glue spraying nozzle realizes glue spraying on the two sides of the bottom cotton in the first direction, while the multiple fixed second glue spraying nozzles 25 realize glue spraying on the two sides and the middle area of the bottom cotton in the first direction. After glue spraying, it retreats back to the feeding conveyor belt 11 again. Then, a spring core 6 is grabbed from the spring core feeding platform 13 by the material grabbing mechanism and placed in the middle area of the bottom cotton to realize the lamination of the spring core 6 and the bottom cotton, forming the first semi-finished product. Then, the first semi-finished product is conveyed to the translation conveyor belt 33 via the feeding conveyor belt 11 and the glue spraying conveyor belt 21. At this time, the side cotton strip laminating assembly is first used to laminate a side cotton strip 61 on one side of the first semi-finished product. After the lamination is completed, it is moved to the other side of the first edge sticking support 32 through the translation conveyor belt 33, and three side cotton strip laminating assemblies are used to laminate side cotton strips 61 on the other three sides of the first semi-finished product, forming the second semi-finished product.

[0062] While the side cotton strip 61 is being laminated on the first semi-finished product, a piece of cotton is grabbed from the bottom / top cotton feeding platform 12 by the material grabbing mechanism and placed on the feeding conveyor belt 11 as the top cotton. Then, the feeding conveyor belt 11 conveys the top cotton to the glue spraying conveyor belt 21, and the first glue spraying nozzle and the second glue spraying nozzles 25 spray glue on the upper surface of the top cotton. When the translation conveyor belt 33 moves to the other side of the first edge sticking support 32, the lifting conveyor belt 32 descends to the same horizontal height as the translation conveyor belt 33. The glue-sprayed top cotton is conveyed from the glue spraying conveyor belt 21 to the lifting conveyor belt 32, and then conveyed by the lifting conveyor belt 32 to the second edge sticking unit 4. At this time, the laminating conveyor belt 43 is on top and the pressing conveyor belt 42 is below, that is, the top cotton will be on the pressing conveyor belt 42. After the lifting conveyor belt 32 conveys the top cotton, it ascends and returns to its original position. The top cotton on the pressing conveyor belt 42 is adsorbed on the pressing conveyor belt 42 through the cooperation of vacuum suckers. Then, the rotating frame 41 rotates 180°, so that the laminating conveyor belt 43 is below and the pressing conveyor belt 42 is above, and the top cotton remains laminated on the pressing conveyor belt 42 through the cooperation of vacuum suckers, waiting for the second semi-finished product.

[0063] The second semi-finished product is moved to the original position driven by the translation conveyor belt 33, conveyed to the laminating conveyor belt 43 by the translation conveyor belt 33, and then the pressing conveyor belt 42 moves downward to press the top cotton on the second semi-finished product to form a spring mattress. Then the pressing conveyor belt 42 moves upward, and the spring mattress is conveyed to the blanking conveyor belt 51 by the laminating conveyor belt 43 for blanking, and the process is completed.
