Description

Technical Field

[0001] This utility model belongs to the field of air mattress technology, and more specifically, it relates to an automatic mattress pressing and pulling machine. Background Technology

[0002] In the mattress manufacturing industry, with the increasing market demand and consumers' ever-increasing requirements for product quality, traditional manual or semi-automatic production methods can no longer meet the needs of large-scale, high-efficiency, and high-quality production. Especially in the pressing and stretching process of mattress production, traditional methods often rely on manual operation, which is not only inefficient but also makes it difficult to guarantee the consistency and stability of the products. As a result, automatic mattress pressing and stretching machines have emerged.

[0003] Application number CN201420165888.X discloses an automatic pressing and pulling machine for producing inflatable column accessories for air mattresses. The machine includes a frame, with an automatic PVC film unwinding mechanism on the first side for unwinding rolled PVC film, and a wave welding device and an automatic winding mechanism on the second side for pulling or rewinding the PVC film to complete the welding process. Several pulling and fixing molds are arranged between the automatic unwinding mechanism and the wave welding device to roll the PVC film into a cylindrical shape during transport. This invention has a simple structure, achieves automated production, has high production efficiency, improves welding quality, reduces the number of operators, lowers the labor intensity of operators, and reduces production costs.

[0004] Based on the above patent search and understanding of the application of existing automatic mattress pressing and pulling machines: if the position of the air mattress is offset during the feeding process of the pressing and pulling stage, it is easy to cause inaccurate positioning in the pressing and pulling stage. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic mattress pressing and pulling machine to address the issue that if the position of the air mattress is offset during the feeding process of the pressing and pulling stage, the position may be inaccurate.

[0006] The technical solution adopted in this utility model is as follows:

[0007] An automatic mattress pressing and pulling machine includes an automatic pressing and pulling machine conveyor frame; a main conveyor belt is provided at the top of the automatic pressing and pulling machine conveyor frame, and an adjusting frame is installed at the rear end of the conveyor frame. A motor is fixedly connected to the right side of the adjusting frame, and the motor shaft is fixedly connected to the right side of a double-threaded rod. The double-threaded rod has threads on both sides, and the threads on both sides of the double-threaded rod are symmetrically designed. The two sides of the adjusting frame are slidably connected to the bottom of a movable frame, and the two movable frames are symmetrically designed. Threaded holes are opened at the lower side of the two movable frames, and the threaded holes of the two movable frames are symmetrically designed. The two sides of the double-threaded rod are located in the threaded holes of the movable frames.

[0008] According to one embodiment of the present invention, a sliding groove is provided on the upper side of each of the movable frames, and an adjusting arm is slidably connected to each movable frame.

[0009] According to one embodiment of the present invention, each of the movable frames has a threaded hole at the top center position, and the bottom position of the threaded hole of each movable frame is connected to the upper position of the movable frame slide groove. A positioning bolt is rotatably connected in the threaded hole of each movable frame, and the bottom position of the positioning bolt is in contact with the top position of the adjusting arm.

[0010] According to one embodiment of the present invention, an auxiliary transport belt is fixedly installed on the inner side of each of the adjusting arms, and the two auxiliary transport belts are symmetrically designed and located on both sides above the main transport belt.

[0011] According to one embodiment of the present invention, a positioning plate is fixedly installed at the front end of each of the auxiliary conveyor belts, and the two positioning plates are symmetrically designed and located on both sides above the main conveyor belt.

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

[0013] 1. The air mattress is conveyed backward by the main conveyor belt. After the motor is started, the motor shaft will drive the double-headed threaded rod to rotate. The two moving frames will move towards each other until the inner sides of the two positioning plates are in contact with the sides of the air mattress, centering the air mattress in the middle of the main conveyor belt and preventing the air mattress from shifting during conveying.

[0014] 2. When the air mattress contacts both sides of the positioning plate and continues to be conveyed to the rear, the two auxiliary conveyor belts start synchronously and turn in the opposite direction to the main conveyor belt. After the air mattress passes under the auxiliary conveyor belt, it is easier to restrict and position the air mattress during the conveying process, so as to avoid contact deviation of the air mattress.

[0024] Example 1:

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] This utility model provides an automatic mattress pressing and pulling machine, including an automatic pressing and pulling machine conveyor frame 1; a main conveyor belt 101 is arranged at the top of the automatic pressing and pulling machine conveyor frame 1; an adjusting frame 2 is installed at the rear end of the automatic pressing and pulling machine conveyor frame 1; a motor 201 is fixedly connected to the right side of the adjusting frame 2; the rotating shaft of the motor 201 is fixedly connected to the right side of a double-threaded rod 202; both sides of the double-threaded rod 202 are threaded, and the threads on both sides of the double-threaded rod 202 are symmetrically designed; the two sides of the adjusting frame 2 are slidably connected to the bottom of a movable frame 203; the two movable frames 203 are symmetrically designed. The two movable frames 203 have threaded holes on their lower sides. The threaded holes of the two movable frames 203 are symmetrically designed. The left and right sides of the double-headed threaded rod 202 are located in the threaded holes of the movable frames 203 respectively. Each movable frame 203 has a sliding groove on its upper side. Each movable frame 203 is slidably connected to an adjusting arm 204. Each movable frame 203 has a threaded hole at the top center. The bottom of the threaded hole of each movable frame 203 is connected to the top of the sliding groove of the movable frame 203. Each movable frame 203 has a rotatably connected positioning bolt 205 in its threaded hole. The bottom of the positioning bolt 205 is in contact with the top of the adjusting arm 204.

[0027] Each adjusting arm 204 has an auxiliary conveyor belt 206 fixedly installed on its inner side. The two auxiliary conveyor belts 206 are symmetrically designed and located on both sides above the main conveyor belt 101. Each auxiliary conveyor belt 206 has a positioning plate 207 fixedly installed at its front end. The two positioning plates 207 are symmetrically designed and located on both sides above the main conveyor belt 101.

[0028] When using:

[0029] The air mattress is placed at the top front end of the main conveyor belt 101. The main conveyor belt 101 transports the air mattress backward. After the motor 201 is started, the motor 201 shaft will drive the double-headed threaded rod 202 to rotate. The two moving frames 203 will move towards each other until the inner sides of the two positioning plates 207 are in contact with the sides of the air mattress, centering the air mattress in the middle of the main conveyor belt 101 and preventing the air mattress from shifting during transport.
