Detailed Implementation

[0023] To make the technical problems solved, the technical solutions and the beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] The embodiments provided by this utility model are as follows: Figures 1-5 As shown, a compression wrapping film pressing mechanism includes a frame 10. A rotating roller 20 is horizontally arranged on the frame 10. A drive gear 30, a first rolling bearing 170, and a second rolling bearing 110 are fixedly sleeved at both ends of the rotating roller 20. The first rolling bearing 170 is located on the innermost side. A sleeve roller 180 is sleeved on the rotating roller 20. The first rolling bearing 170 is fixed at both ends of the sleeve roller 180. A rack 40 that meshes with the drive gear 30 is vertically fixed on the frame 10. Lifting areas 11 are respectively opened on both sides of the frame 10. Both ends of the rotating roller 20 pass through the lifting areas 11 on both sides. A guide rod assembly 50 is vertically fixed in the lifting area 11. A support plate 120 is slidably arranged on the guide rod assembly 50. The second rolling bearing 110 is fixedly arranged on the support plate 120. A sliding plate 60 is fixedly arranged on the support plate 120. A drive assembly 160 is arranged on the sliding plate 60. The drive assembly 160 is used to drive the rotating roller 20 to rotate around its own axis.

[0025] During use, the mattress with the film is prepared to pass through the pressing mechanism. At this time, the two ends of the rotating roller 20 are at the bottom of the lifting area 11. The operator starts the drive assembly 160, which drives the rotating roller 20 to rotate. The rotating roller 20 drives the drive gear 30 to rotate. Since the drive gear 30 meshes with the rack 40, the drive gear 30 moves upward, driving the rotating roller 20 to move upward. When the mattress moves directly under the rotating roller 20, the operator uses the drive assembly 160 to make the rotating roller 20 rotate in the opposite direction. The rotating roller 20 drives the drive gear 30 to rotate in the opposite direction, and the drive gear 30 drives the rotating roller 20 to move downward until the rotating roller 20 falls onto the mattress with the film. The drive assembly 160 stops working, and the sleeve roller 180 contacts the film. The mattress continues to move forward, and the sleeve roller 180 flattens the film onto the mattress, realizing the pressing process of the mattress film. After the mattress leaves the rotating roller 20, the rotating roller 20 continues to fall under the action of gravity. When the two ends of the rotating roller 20 fall to the bottom of the lifting area 11, the falling stops and the reset is completed.

[0026] Preferably, the drive assembly 160 includes a drive motor 70 and a transmission chain 80. The drive motor 70 is fixedly mounted on the sliding plate 60, and the transmission chain 80 is vertically mounted on the sliding plate 60. The output end of the drive motor 70 is connected to the driving end of the transmission chain 80, and the end of the rotating roller 20 is connected to the driven end of the transmission chain 80.

[0027] Preferably, the transmission chain 80 includes a driving gear 81, a driven gear 82, and a gear chain 83. The two ends of the gear chain 83 are respectively sleeved on the driving gear 81 and the driven gear 82 and mesh with them. The driving gear 81 is fixedly sleeved on the output end of the drive motor 70, and the driven gear 82 is fixedly sleeved on the end of the rotating roller 20.

[0028] Preferably, the sliding plate 60 has a U-shaped groove 90, the drive motor 70 is located on one side of the sliding plate 60, the transmission chain 80 is located on the other side of the sliding plate 60, the output end of the drive motor 70 passes through the sliding plate 60 and is connected to the drive gear 81, and the rotating roller 20 passes through the U-shaped groove 90 and is connected to the driven gear 82.

[0029] Preferably, the driven gear 82 is positioned directly below the driving gear 81, which facilitates the installation and replacement of the drive motor 70 by the staff.

[0030] Preferably, a linear bearing 100 is slidably sleeved on the guide rod assembly 50, and the support plate 120 is fixed on the linear bearing 100. By setting the linear bearing 100, the support plate 120 is made more stable when sliding up and down, preventing the rotating roller 20 from shaking when moving up and down, which would affect its use.

[0031] Preferably, the support plate 120 is disposed in the lifting area 11, and the support plate 120 can contact the bottom of the lifting area 11. By replacing the rotating roller 20 with the support plate 120 in contact with the bottom of the lifting area 11, direct contact between the rotating roller 20 and the bottom of the lifting area 11 can be avoided, thus preventing the rotating roller 20 from deforming after long-term use.

[0032] Preferably, a mounting plate 130 is fixedly installed on the frame 10, and the rack 40 is fixed on the mounting plate 130. When the rack 40 wears out after long-term use, the mounting plate 130 makes it convenient for staff to install and replace the rack 40.

[0033] Preferably, a support rod 140 is horizontally arranged below the rotating roller 20. The two ends of the support rod 140 are fixedly connected to the two sides of the frame 10 respectively. The support rod 140 supports the frame 10 and prevents the frame 10 from shaking when the pressing mechanism is working, thus affecting production efficiency.

[0034] Preferably, adjustable bases 150 are provided at the bottom of both sides of the frame 10, and the two are threadedly connected. The height of the frame 10 can be adjusted by adjusting the relative position of the adjustable bases 150 and the bottom of the frame 10.

[0035] The working principle of this embodiment, and its more specific process, are as follows:

[0036] The mattress with the film is about to pass through the pressing mechanism. At this time, the two ends of the rotating roller 20 are located at the bottom of the lifting area 11, and the support plate 120 is in contact with the bottom of the lifting area 11. The operator starts the drive motor 70, which drives the drive gear 81 to rotate. The drive gear 81 drives the gear chain 83 to rotate through meshing. The gear chain 83 drives the driven gear 82 to rotate through meshing. The driven gear 82 drives the rotating roller 20 to rotate. The rotating roller 20 drives the drive gear 30 to rotate. Since the drive gear 30 meshes with the rack 40, the drive gear 30 moves upward, driving the rotating roller 20 to move upward. The rotating roller 20 drives the support plate 120 to move upward, which in turn drives the drive motor 70 on the sliding plate 60 and the drive chain 40 to rotate. The moving chain 80 moves upward, and the support plate 120 separates from the bottom of the lifting area 11. When the mattress moves directly under the rotating roller 20, the operator controls the drive motor 70 to rotate in the opposite direction. The rotating roller 20 drives the drive gear 30 to rotate in the opposite direction, and the drive gear 30 drives the rotating roller 20 to move downward until the rotating roller 20 falls onto the mattress with the film. The drive motor 70 stops working, and the sleeve roller 180 contacts the film. The mattress continues to move forward, and the sleeve roller 180 flattens and presses the film onto the mattress, realizing the pressing process of the mattress film. After the mattress leaves the rotating roller 20, the rotating roller 20 continues to fall under the action of gravity until the support plate 120 re-contacts the bottom of the lifting area 11. The rotating roller 20 stops falling and completes the reset.

[0037] The compression wrapping film pressing mechanism of this utility model has a rotating roller 20 horizontally arranged on the frame 10, with drive gears 30 fixedly sleeved at both ends of the rotating roller 20, and a sleeve roller 180 sleeved on the rotating roller 20. A rack 40 that meshes with the drive gears 30 is vertically fixed on the frame 10, and a sliding plate 60 is slidably arranged on the frame 10. A drive assembly 160 is arranged on the sliding plate 60. This allows the compression wrapping film pressing mechanism to press the film flat and aesthetically pleasingly onto the mattress, improving the appearance of the compressed packaging.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
