Description

Technical Field

[0001] This utility model belongs to the field of film production machinery technology, and in particular to an automatic tube feeding device. Background Technology

[0002] With the increasing use of film, automatic film winding machines are becoming increasingly automated. The film is typically wound onto a roll, inside which a weight-bearing spool is installed. After the film is wound, the spool needs to be pulled off the roll, and the film and roll proceed to the next process. The pulled-off spool is then fed back into a new roll for further film winding. In existing technology, the spool is pulled off the roll by a push-out device on one side of the roll, which requires the push-out device to have a long stroke and a complex structure. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an automatic tube pulling device that uses a clamping device to rotate out the spool and reduces the pushing stroke of the tail end ejection device.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: The automatic tube pulling device includes an automatic tube pulling frame, a front-end pulling device, a front-end top shaft device, a tail-end top shaft device, and a tube winding support frame. The front-end pulling device and the tail-end top shaft device are arranged on both sides of the automatic tube pulling frame. The front-end top shaft device can be raised and lowered on the automatic tube pulling frame and is arranged on the side of the front-end pulling device away from the tail-end top shaft device. The tube winding support frame is arranged on the side of the front-end top shaft device away from the front-end pulling device. The front-end pulling device includes an upper clamping device, a lower clamping device, and a rotation drive device. The upper clamping device or the lower clamping device is connected to the rotation drive device.

[0005] Preferably, the upper clamping device includes an upper roller and an upper rotating shaft, the upper roller being fixed on the upper rotating shaft, and the upper rotating shaft being connected to a rotation drive device; the lower clamping device includes a lower roller and a lower rotating shaft, the lower roller being fixed on the lower rotating shaft.

[0006] Preferably, the upper clamping device includes an upper roller and an upper rotating shaft, with the upper roller fixed on the upper rotating shaft, and the lower clamping device includes a lower roller and a lower rotating shaft, with the lower roller fixed on the lower rotating shaft, and the lower rotating shaft connected to a rotation drive device.

[0007] Preferably, the front-end extraction device further includes an upper gear and a lower gear, with the upper gear mounted on the upper rotating shaft and the lower gear mounted on the lower rotating shaft, and the upper gear meshing with the lower gear.

[0008] Preferably, the front-end extraction device further includes an extraction lifting drive device and a sliding support plate. The sliding support plate is disposed on the upper rotating shaft, and the extraction lifting drive device is disposed on the upper side of the sliding support plate and connected to the sliding support plate.

[0009] Preferably, the diameters of the upper and lower rollers gradually increase from the middle to both ends.

[0010] Preferably, the front-end top shaft device and the rear-end top shaft device have the same pushing stroke.

[0011] Preferably, the front-end top shaft device includes a front-end top shaft drive device, which is mounted on the automatic tube pulling machine frame, with the driven part of the front-end top shaft drive device facing the front-end extraction device.

[0012] Preferably, it also includes a front lifting drive device, which is disposed on the upper side of the front top shaft device to drive the front top shaft device to lift.

[0014] Compared with existing technologies, the beneficial effects of this technical solution are:

[0015] This invention features a front-end extraction device at the front end of an automatic tube-spinning machine frame, which works in conjunction with a tail-end top shaft device at the tail end. The tail-end top shaft device simply pushes one end of the roll out, where it is clamped by the upper and lower clamping devices of the front-end extraction device. A drive mechanism rotates the clamping devices, thus extracting the roll. This reduces the pushing stroke of the tail-end top shaft device. The extracted roll is placed on a tube support frame. When a new roll falls onto the automatic tube-spinning machine frame, the front-end extraction device reverses to retract the roll into the new roll. The front-end top shaft device then pushes the roll completely back into the new tube. The overall structure is simple and easy to operate. Attached Figure Description

[0022] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0023] Example 1:

[0024] Reference Figure 1 The automatic tube pulling device includes an automatic tube pulling frame 1, a front-end pulling device 2, a front-end top shaft device 3, a tail-end top shaft device 4, and a tube winding support frame 5. The front-end pulling device 2 and the tail-end top shaft device 4 are mounted on the automatic tube pulling frame 1 and are located on both sides of the drum 9. The front-end top shaft device 3 is vertically mounted on the automatic tube pulling frame 1 and is located on the side of the front-end pulling device 2 away from the drum 9. The tube winding support frame 5 is located on the side of the front-end top shaft device 3 away from the drum 9.

[0025] The front end extraction device 2 includes a front end clamping device, which includes an upper clamping device and a lower clamping device. The two ends of the roll are provided with inward grooves. After being pushed out by the tail end top shaft device 4, the grooves of the roll pass through the upper clamping device and the lower clamping device. The roll is located between the front end clamping device. The rotation drive device drives the front end clamping device to rotate and extract the roll.

[0026] Reference Figures 2-5 In this embodiment, a pull-out lifting drive device is also provided. The pull-out lifting drive device drives the upper clamping device to descend. The upper clamping device is connected to the upper gear 202, thereby driving the upper gear 202 to descend until it meshes with the lower gear 203. The lower gear 203 is connected to the lower clamping device. The rotation drive device drives the upper gear 202 and the lower gear 203 to rotate, thereby driving the upper clamping device and the lower clamping device to rotate. The spool clamped between the upper clamping device and the lower clamping device is rotated to pull out the spool 9.

[0027] Specifically, the film-wound roll 9 is fed to the roll support frame on the automatic tube-pulling machine frame 1. The roll 9 is equipped with a weight-increasing spool, the length of which is greater than the length of the roll 9. Support cylinders 10 are provided at both ends of the spool. The support cylinders 10 are fixed to the automatic tube-pulling machine frame 1 by support shaft clamping devices on both sides of the roll support frame. When the spool is pulled out of the roll 9, the roll 9 and the film automatically fall to the next process. Then, a new roll 9 rolls onto the roll support frame, and the spool is pushed back into the roll 9.

[0028] The front-end fixing frame 201 is set on the automatic tube pulling machine frame 1 and is located on the side of the support shaft clamping device away from the drum 9. The front-end fixing frame 201 has two layers, an open fixing box on the upper layer and a fixing plate on the lower layer. The fixing box and the fixing plate are connected by side plates on both sides. The upper clamping device and the lower clamping device are located in the rotation space between the fixing box and the fixing plate.

[0029] The upper clamping device includes an upper roller 204, an upper rotating shaft 206, and a sliding support plate 208. The upper roller 204 is fixedly installed in the middle position of the upper rotating shaft 206. The two side plates of the front fixing frame 201 are provided with sliding grooves. The two ends of the upper rotating shaft 206 pass through the sliding grooves respectively. One end is connected to the upper gear 202, and the other end is connected to the rotation drive device. The rotation drive device is fixedly installed on the outside of the side plate. The sliding support plate 208 is fixedly mounted in an inverted U-shape on the upper rotating shaft 206 and is rotatably connected to the upper rotating shaft 206 via a bearing. The upper side is connected to the pull-out lifting drive device. In this embodiment, the lifting drive device is a pull-out lifting cylinder 210. The pull-out lifting cylinder 210 is fixed on the top plate of the upper fixed box of the front fixed frame 201. The push rod of the pull-out lifting cylinder 210 and the guide rods on both sides are connected to the sliding support plate 208, driving the sliding support plate 208 and the upper rotating shaft 206 to rise and fall, thereby driving the upper gear 202 to rise and fall and mesh with and separate from the lower gear 203 mounted on the lower rotating shaft 207.

[0030] The lower clamping device includes a lower roller 205 and a lower rotating shaft 207. Similarly, the lower roller 205 is fixedly installed in the middle position of the lower rotating shaft 207. The lower rotating shaft 207 is rotatably mounted on the side plate through a bearing. The lower rotating shaft 207 is located below the upper rotating shaft 206. One end passes through the side plate and connects to the lower gear 203, and the other end is rotatably mounted on the side plate through a bearing.

[0031] In this embodiment, the rotation drive device is a pull-out rotation motor 209. When the pull-out rotation motor 209 drives the lower rotating shaft 207 to rotate clockwise, the lower gear 203 rotates clockwise, driving the upper gear 202 to rotate counterclockwise, thereby driving the upper roller 204 to rotate clockwise and the lower roller 205 to rotate counterclockwise. The diameters of the upper roller 204 and the lower roller 205 gradually increase from the middle to both ends, forming a meshing groove. The spool is pushed out by the tail end ejection device 4 and stuck in the middle meshing groove. The clockwise rotation of the upper roller 204 and the counterclockwise rotation of the lower roller 205 simultaneously apply an outward pushing force to the upper and lower sides of the spool, thereby pulling out the spool. When the pull-out rotation motor 209 rotates in the opposite direction, it can push the spool back into the drum.

[0032] The front-end top shaft device 3 is located on the side of the front-end extraction device 2 away from the drum 9, and includes a front-end top shaft drive device and a front-end lifting drive device. In this embodiment, the front-end top shaft drive device is a front-end ejection cylinder 301, and the front-end lifting drive device is a front-end lifting cylinder 302. The front-end lifting cylinder 302 is fixedly mounted on the fixing plate on the lower layer of the front-end fixing frame 201. The fixing plate has three horizontal through holes on the side away from the drum. The three push rods of the front-end lifting cylinder 302 pass vertically upward through the through holes and connect to the front-end ejection cylinder support plate. The push rods on both sides serve as guides. The front-end ejection cylinder 301 is mounted on the front-end ejection cylinder support plate, and the push rods are horizontally oriented towards the rollers.

[0033] When the reel is pulled out by the front-end extraction device 2, the front-end top shaft device 3 descends to its lowest position to avoid obstructing the reel's extraction. The end of the automatic tube-pulling machine frame 1 is equipped with a sliding tube support frame 5. One end of the horizontal guide rod of the tube support frame 5 is connected to a slide rail located on the lower side of the automatic tube-pulling machine frame 1 via a slider, and the other end is connected to a vertical upright. The upright has wheels on its lower side and a horizontal reel support rod on its upper side. When the roll is pulled out, one end is supported by the horizontally sliding roll support frame 5, and the other end is supported by the support cylinder 10. The roll 9 separates from the film and falls to the next process. After the new roll 9 is placed on the roll support frame, the extraction rotation motor 209 of the front extraction device 2 reverses, driving the roll back into the roll. At this time, the roll cannot be completely returned into the support cylinder 10. The front lifting cylinder 302 drives the front ejection cylinder 301 to rise until the push rod is the same height as the roll. The push rod of the front ejection cylinder 301 drives the roll to completely return into the support cylinder 10.

[0034] The tail end top shaft device 4 is located on the opposite side of the front end extraction device 2, including a tail end ejection cylinder 401 and a tail end support frame 402. The tail end support frame 402 is fixed on the automatic tube extraction machine frame 1. The tail end ejection cylinder 401 is horizontally arranged on the tail end support frame 402, and the push rod is horizontally arranged towards the reel.

[0035] Work process:

[0036] The film-wound roll 9 is fed onto the roll support frame on the automatic tube-pulling machine frame 1. The tail-end ejector cylinder 401 drives its push rod to push the roll out a certain distance. The end of the roll near the front-end extraction device 2 passes between the upper roller 204 and the lower roller 205. The extraction lifting cylinder 210 drives the upper roller 204 and the upper gear 202 to descend until the upper gear 202 meshes with the lower gear 203. At the same time, the upper roller 204 and the lower roller 205 clamp the roll. The extraction rotation motor 209 drives the lower gear 203 and the upper gear 202 to rotate in opposite directions, thereby extracting the roll until it is detached from the roll 9. One end of the roll... Supported by the roll support frame 5 at one end and the support tube 10 at the other end, the roll 9 and the film fall to the next process. The new roll 9 falls onto the roll support frame. The pull-out rotating motor 209 reverses to push the spool back into the new roll 9. The front lifting cylinder 302 drives the front ejection cylinder 301 to rise to the highest height. At this time, the push rod is at the same height as the spool. The front ejection cylinder 301 drives the push rod to push the spool completely back into the roll 9. The robot transports the roll 9 and the spool to the film winding process. The roll 9 after film winding is then sent to the roll support frame on the automatic tube pulling machine frame 1. This operation is repeated.

[0038] The difference between this embodiment and Embodiment 1 is that: the lower clamping device is connected to the rotation drive structure, and the lower rotating shaft 207 passes through the side plate and is connected to the rotation drive motor 209, which drives the lower rotating shaft 207 to rotate.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
