Description

Technical Field

[0001] The utility model belongs to the field of mattress packaging equipment, in particular to an alignment structure of a feeding end of a polyolefin sponge packaging production line. Background Art

[0002] Polyolefin foam pad packaging lines are essential tools for modern mattress production, primarily used for automated packaging of finished polyolefin foam pads. However, existing packaging lines lack alignment at the feed end, which can easily cause material misalignment. This in turn affects the stability of the mattress during packaging, potentially resulting in loose packaging and uneven appearance, reducing product competitiveness. Furthermore, unstable material positioning increases equipment failure rates, such as material jams and downtime, impacting production efficiency, accelerating equipment wear, and increasing maintenance costs.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] As attached Figure 1-6The alignment structure of the feed end of a polyolefin sponge packaging production line shown in the figure includes a feeding component 1, and the discharge end of the feeding component 1 is installed with a stop alignment component 2. The feeding component 1 includes a frame 3, and the upper part of the frame 3 is provided with conveying rollers 4 at the feeding end and the discharge end. The two conveying rollers 4 are sleeved with the same closed-loop conveyor belt 5, wherein the conveying roller 4 at the discharge end is connected to the feeding motor 7 through a worm gear transmission box 6, and the closed-loop conveyor belt 5 is driven by the feeding motor 7 to circulate the feeding. The frame 3 is evenly provided with two supporting rollers 8 at corresponding positions below the upper part of the closed-loop conveyor belt 5. The upper part of the closed-loop conveyor belt 5 is in contact with the upper surface of the supporting roller 8, and the extension direction of the supporting roller 8 is perpendicular to the conveying direction.

[0020] The stopping and alignment component 2 includes a lifting cylinder 9 as a lifting structure and a stopping rod 10 as a stopping structure. The lifting cylinder 9 is fixedly installed to the middle of the side of the discharge end of the frame 3. The lifting end of the lifting cylinder 9 is fixedly installed with a mounting seat 11, and a swing seat 12 is rotatably installed on the mounting seat 11. The stopping rod 10 is fixedly installed on the swing seat 12, and the swing seat 12 swings relative to the mounting seat 11 in the feeding direction. The stopping structure is driven by the lifting structure to rise to a position higher than the upper surface of the closed-loop conveyor belt 5 of the feeding component 1 or to fall to a position lower than the upper surface of the closed-loop conveyor belt 5 of the feeding component 1.

[0021] As a preferred embodiment, guide light shafts 13 are fixedly installed at both ends of the stop rod 10, and a guide seat 14 that slides with the guide light shaft 13 is fixedly installed on the side of the discharge end of the frame 3 of the feeding assembly 1. The cooperation between the guide seat 14 and the guide light shaft 13 improves the stability and smoothness of the rise and fall of the stop rod 10.

[0022] The alignment structure provided in this embodiment cooperates with the packaging equipment to form a complete packaging production line when in use. The alignment structure is arranged upstream of the packaging equipment, that is, the feed end of the packaging production line, and can be connected to the production equipment and the production equipment provides the completed polyolefin sponge pad.

[0023] When the polyolefin sponge pad falls onto the closed-loop conveyor belt 5, it is driven by the closed-loop conveyor belt 5 to move toward the discharge end. At this time, the lifting cylinder 9 drives the stop rod 10 to rise. When the polyolefin sponge pad touches the stop rod 10, it will be intercepted by the stop rod 10 and stop moving forward. However, the closed-loop conveyor belt 5 is still rotating and providing driving force to the polyolefin sponge pad. If the polyolefin sponge pad is in a misaligned state, this driving force will cause the polyolefin sponge pad to swing to one side and completely fit with the stop rod 10, completing the alignment task. Then the lifting cylinder 9 drives the stop rod 10 to descend, and the polyolefin sponge pad is driven by the closed-loop conveyor belt 5 to enter the packaging equipment and be packaged by the packaging equipment. Since the alignment operation is performed before packaging, the packaging quality and packaging stability are improved.

[0024] The above-described embodiment merely represents one embodiment of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
