Description

Technical Field:

[0001] The utility model relates to the technical field of cardboard processing equipment, and more specifically, to a bottom pressing mechanism for the bottom of a long cylindrical paper tube. Background Art:

[0002] For existing packaging accessories such as paper tubes, during their processing, generally, the bottom plate needs to be thickened. Therefore, a thick plate or thick sheet needs to be padded on the bottom plate, and after being adhesively fixed with an adhesive, it is then pressed to improve the strength of its bottom plate and its load-bearing effect.

[0003] The existing pressing is generally to place it in a bottom pressing machine for processing. The existing bottom pressing machine generally includes a frame, a pressing oil cylinder is installed on the upper part of the frame, and a pressing plate is fixed to the bottom end of the push rod of the pressing oil cylinder. And a support column is placed, and a lower support plate is fixed to the top end of the support column. The cylindrical body is inverted and inserted on the support column. At this time, the bottom plate becomes the top plate and is above the support column. Then, the upper pressing plate descends to press. However, for its disassembly and assembly, the support column needs to be moved away from the position below the pressing plate. The existing methods are all manually moved by hand for loading and unloading, with low efficiency and poor effect. There are also those that use cylinders or the like to move the support column to move for loading and unloading. However, none of them can achieve continuous processing, and the efficiency is low. Summary of the Utility Model:

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a bottom pressing mechanism for the bottom of a long cylindrical paper tube. It can rotate the annular plate to realize the rotation and movement of the lower support pressing plate along with the annular plate, so that it can continuously carry out the loading, unloading and bottom pressing processing of the paper tube, greatly improving the production efficiency and greatly reducing the labor intensity of workers, with good effect.

[0016] Embodiment, as shown in Figures 1 to 3 A bottom pressing mechanism for the bottom of a long cylindrical paper tube, including a fixed bottom plate 10. The left part of the top surface of the fixed bottom plate 10 is fixed with an upper support frame 11. The middle of the top surface of the upper fixed beam 111 of the upper support frame 11 is fixed with a pressing oil cylinder 12. The bottom end of the push rod of the pressing oil cylinder 12 extends out of the bottom surface of the upper fixed beam 111 of the upper support frame 11 and is fixed with an upper pressing plate 13.

[0017] A rotating mechanism 20 is installed on the fixed bottom plate 10. On the left and right parts of the top surface of the annular plate 22 of the rotating mechanism 20, vertical main cylinders 30 are fixed (the included angle between the central axes of the two vertical main cylinders 30 and the central axis of the annular plate 22 is 180 degrees, that is, they are on the same straight line). At the top end of the vertical main cylinder 30, a lower support pressing plate 31 is installed. The lower support pressing plate 31 corresponds to the bottom surface of the upper pressing plate 13 and cooperates with the upper pressing plate 13.

[0018] Further, the rotating mechanism 20 includes an annular bottom guiding track block 23. The bottom surface of the bottom guiding track block 23 is fixed on the top surface of the fixed bottom plate 10. The upper support frame 11 includes an upper fixed beam 111. On the left and right parts of the bottom surface of the upper fixed beam 111, vertical support rods 112 are fixed. The bottom ends of the vertical support rods 112 are fixed on the top surface of the fixed bottom plate 10. The right vertical support rod 112 is inserted into the middle through hole of the bottom guiding track block 23.

[0019] In the middle of the top surface of the bottom guiding track block 23, an annular guide groove 231 is formed. The annular plate 22 is directly above the bottom guiding track block 23. An annular sliding block 24 is installed on the bottom surface of the annular plate 22. The annular sliding block 24 is inserted into the annular guide groove 231 and cooperates with the annular guide groove 231.

[0020] Further, a wear-resistant lubricating layer 232 is fixed on the inner side wall of the annular guide groove 231. The outer side wall and the bottom surface of the annular sliding block 24 are in close contact with the corresponding wear-resistant lubricating layer 232. The wear-resistant lubricating layer 232 can improve the rotation effect when the annular sliding block 24 rotates along the annular guide groove 231, reduce jamming and wear, and ensure its use effect.

[0021] Further, an annular gear ring 25 is fixed on the bottom surface of the annular plate 22. The annular sliding block 24 is fixed on the bottom surface of the annular gear ring 25. On the right side of the top surface of the fixed bottom plate 10, a support frame 50 is fixed. On the top surface of the top plate of the support frame 50, a rotating servo motor 51 is fixed. The bottom end of the output shaft of the rotating servo motor 51 extends out of the bottom surface of the top plate of the support frame 50 and is fixed with a driving gear 52. The driving gear 52 meshes with the annular gear ring 25.

[0022] Around the middle through hole of the annular gear ring 25, a lower guide sleeve is fixed on the bottom surface. An outer sleeve is fixed on the top surface of the fixed bottom plate 10. An inner self-lubricating sleeve is fixed on the inner side wall of the outer sleeve. The lower guide sleeve is inserted into the outer sleeve. The inner side wall of the inner self-lubricating sleeve is in close contact with the outer side wall of the lower guide sleeve. The outer sleeve plays a role in guiding and limiting the lower guide sleeve.

[0023] Furthermore, a vertical screw hole 32 extending downward is formed in the middle of the top surface of the vertical main cylinder body 30. A vertical screw rod 33 is fixed in the middle of the bottom surface of the lower support pressing plate 31, and the vertical screw rod 33 is screwed in the vertical screw hole 32. An elastic protective ring plate 34 is fixed on the top surface of the vertical main cylinder body 30, and the bottom surface of the lower support pressing plate 31 is pressed against the top surface of the elastic protective ring plate 34. The height position of the lower support pressing plate 31 can be adjusted by rotating the vertical screw rod 33. However, when adjusting the height, a gasket needs to be placed on the elastic protective ring plate 34 to ensure that the top surface of the gasket is pressed against the bottom surface of the lower support pressing plate 31 to ensure the supporting force.

[0024] Furthermore, a reinforcing plate 1 is fixed to the bottom surface of the upper pressing plate 13. The reinforcing plate 1 is fixedly connected to the bottom surface of the upper pressing plate 13 by bolts. This structure enables the reinforcing plate 1 to be disassembled and replaced only when it is damaged, and the replacement is convenient.

[0025] Furthermore, an induction column 2 is fixed to the bottom surface of the side of the annular gear ring 25 facing the vertical main cylinder body 30. An induction support frame 3 is fixed to the top surface of the fixed bottom plate 10 below the induction column 2. A proximity switch 4 is fixed to the top plate of the induction support frame 3, and the sensing of the proximity switch 4 corresponds to the bottom end of the induction column 2.

[0026] In this embodiment, the proximity switch 4 and the rotary servo motor 51 are both electrically connected to the control host through electric connection lines. The pressing oil cylinder 12 is communicated with the hydraulic system through a connecting oil pipe (the hydraulic system is connected by an oil tank, an oil pump, a solenoid valve, etc. This is a common structure and will not be elaborated here. The hydraulic system is also controlled by the control host to operate).

[0027] In this embodiment, vertical main cylinder bodies 30 are fixed to the top surfaces of the left and right parts of the annular plate 22. It is also possible to fix vertical main cylinder bodies 30 to the left, right, front, and rear parts of the annular plate 22 (the four vertical main cylinder bodies 30 are evenly distributed on the top surface of the annular plate 22 with the central axis of the annular plate 22 as the center, that is, the central axes of every two adjacent vertical main cylinder bodies 30 and the central axis of the annular plate 22 form a 90-degree angle). It is necessary to ensure that an induction column 2 is fixed to the bottom surface of one side of the corresponding vertical main cylinder body 30. In this way, when the rotary servo motor 51 operates, the corresponding induction column 2 can be sensed by the proximity switch 4, indicating that the lower support pressing plate 31 of one of the vertical main cylinder bodies 30 is directly below the upper pressing plate 13. At this time, the bottom pressing operation can be carried out.

[0028] In the use of this embodiment, a paper tube to be processed can be sleeved on the vertical main cylinder body 30 on the right side. At this time, the bottom plate is in the top position and presses against the top surface of the lower support pressing plate 31. Then, by running the rotary servo motor 51, the driving gear 52 drives the annular gear 25 to rotate until the proximity switch 4 senses an induction column 2, indicating that the vertical main cylinder body 30 with the paper tube installed is directly below the upper pressing plate 13. Then, through the push rod of the pressing oil cylinder 12, the top surface of the reinforcing plate 1 presses against the top surface of the bottom plate of the paper tube to press it tightly, realizing the bottom pressing operation. At this time, another vertical main cylinder body 30 is on the right side, and another paper tube can be manually placed on the vertical main cylinder body 30 to complete the feeding;

[0029] After the pressing is completed, the push rod of the pressing oil cylinder 12 retracts. By running the rotary servo motor 51, the subsequent vertical main cylinder body 30 can be moved directly below the upper pressing plate 13, and the processed paper tube can be moved out to the right side. At this time, manual unloading and reloading are carried out. The effect is good and the efficiency is high. Connecting processing can be realized, greatly improving the processing efficiency.
