Technical Field

[0001] The invention relates to the technical field of ground film production, in particular to an automatic tube core threading device for ground film production. Background Art

[0002] Ground film is a ground covering film, usually a transparent or black PE film, but also a green or silver film. It is used for ground covering to increase soil temperature, retain soil moisture, maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, and promote plant growth. With the rapid development of the manufacturing industry, the requirements for production efficiency and safety are becoming higher and higher. In the production line of ground film, ground film winders play a vital role. However, in the traditional operation method, after the ground film roll is pulled out of the mandrel, the replacement of the empty tube core often depends on manual operation-that is, the empty tube core is manually inserted onto the mandrel, and then moved to the roll changing position with the help of a robot. This process is not only time-consuming and labor-intensive, but also limits the improvement of production efficiency.

[0003] The Chinese patent publication has a patent number of CN221253276U, which is an automatic tube core insertion device.

[0015] See also Figure 1-7, an automatic tube core threading device for mulch film production, comprising a frame 1, a controller arranged on the frame 1, and a core shaft positioning support guide device 2 located on one side of the frame 1; the core shaft positioning support guide device 2 comprises a mounting plate 3 located on one side of the frame 1, a support base frame connected to both ends of the lower side of the mounting plate 3 respectively, a second side plate 6 connected to one end of the upper side of the mounting plate 3 and close to one side of the frame 1, a support arc groove 7 arranged on the upper side of the second side plate 6, a first side plate 4 connected to the other end of the upper side of the mounting plate 3, a sliding positioning mechanism 5 arranged on one side of the first side plate 4, two cylinders 10 installed on the lower side of the mounting plate 3 and arranged at intervals, and a support guide connected to the output ends of the two cylinders 10 and located between the first side plate 4 and the second side plate 6. The automatic monitoring mechanism is provided on the upper side of the mounting plate 3 and between the first side plate 4 and the supporting guide mechanism, and the automatic monitoring mechanism is provided on the upper side of the second side plate 6 and on one side of the supporting arc groove 7. The automatic monitoring mechanism, the two cylinders 10, and the core shaft supporting mechanism are all electrically connected to the controller. The two cylinders 10 are both located between the two supporting bases, and the sliding positioning mechanism 5 is located on one side of the core shaft supporting mechanism. In the process of ground film production, when it is necessary to install the tube core on the film roll core shaft 21, first, the clamping head 22 at one end of the core shaft 21 is embedded in the sliding positioning mechanism 5, and the other end is overlapped in the supporting arc groove 7. Subsequently, the two cylinders 10 are activated by the command of the controller to drive the supporting guide mechanism to rise, and the core shaft 21 is moved to the The core 21 is initially fixed to the position of the core 21 by the manipulator installed on the frame 1. Then, the empty core is grasped by the manipulator installed on the frame 1, and the core is pushed horizontally through the coordinated action of the linear slide module, the straight cylinder and the sleeve. When the head end of the core passes through one end of the core 21 smoothly, the automatic monitoring mechanism captures the position information of the core as it continues to move horizontally, and feeds back the signal to the controller in real time. The controller then controls the two cylinders 10 and the core support mechanism to start synchronously, and drives the support guide mechanism connected to the two cylinders 10 to descend, thereby releasing the support for the core 21. 1, at the same time, the mandrel support mechanism supports the other end of the mandrel 21, preventing the possible decline caused by the clamping head 22 being located in the sliding positioning mechanism 5. As the tube core continues to move, when it reaches the top of the support guide mechanism, the support guide mechanism provides support and guidance for the movement of the tube core, ensuring that the tube core can be smoothly inserted into the mandrel 21, completing the tube core insertion operation; the device solves the problem that the mandrel 21 is inconvenient to fix and easy to roll during the current tube core insertion process, not only can it support and fix the mandrel 21 while ensuring that the head end of the tube core can be accurately inserted into one end of the mandrel 21, but also provides continuous and stable support and guidance for subsequent tube insertion operations, thereby improving production efficiency.

[0016] The supporting and guiding mechanism comprises a U-shaped frame 11 connected to the output ends of the two cylinders 10, inclined recesses 12 respectively arranged on both sides of the U-shaped frame 11, a U-shaped connecting shell 13 connected in the inclined recess 12, and a plurality of guide rollers 14 rotatably connected in the U-shaped connecting shell 13 and arranged at intervals along the length direction of the U-shaped connecting shell 13, and the two inclined recesses 12 are arranged relatively to each other; in the process of the supporting and guiding mechanism supporting the core shaft 21 and the tube core, the plurality of guide rollers 14 arranged in the two U-shaped connecting shells 13 play a supporting and guiding role, and these guide rollers 14 are arranged in two groups in an inclined relative manner, so as to provide a stable support for the core shaft 21 and the tube core. In addition, as the tube core moves, these guide rollers 14 also play an important role in guiding the horizontal movement of the tube core, thereby ensuring the stability of the movement.

[0017] The sliding positioning mechanism 5 includes two L-shaped shells 17 connected to one side of the first side plate 4 and arranged at intervals, and a limiting bottom plate 18 connected to the lower sides of the two L-shaped shells 17, and the two L-shaped shells 17 are arranged relative to each other; when the clamping head 22 at one end of the core shaft 21 is connected to the sliding positioning mechanism 5, the clamping head 22 first enters from the upper end opening of the two L-shaped shells 17. During this process, the core shaft 21 connected to the clamping head 22 will pass through the space between the two L-shaped shells 17 and continue to extend to the other side of the two L-shaped shells 17. At this time, the limiting bottom plate 18 limits the downward movement of the clamping head 22, thereby ensuring that the sliding positioning mechanism 5 can fix one end of the core shaft 21.

[0018] The core shaft support mechanism includes an electric push rod 15 installed on the upper side of the mounting plate 3, and a U-shaped support frame 16 connected to the output end of the electric push rod 15, and the electric push rod 15 is electrically connected to the controller; the electric push rod 15 is activated by the controller, and the electric push rod 15 immediately drives the U-shaped support frame 16 to rise until the U-shaped support frame 16 supports one end of the core shaft 21, thereby facilitating the support of one end of the core shaft 21 and preventing the core shaft 21 from sliding downward from the two L-shaped shells 17.

[0019] The automatic monitoring mechanism includes a mounting base 19 connected to the upper side of the second side plate 6, and a displacement sensor 20 installed at one end of the mounting base 19 and corresponding to one side of the supporting arc groove 7. The displacement sensor 20 is electrically connected to the controller; when the tube core passes through the monitoring area of ​​the displacement sensor 20 during movement, the displacement sensor 20 will capture and transmit the monitored position information to the controller, and then the controller will control the starting operation of the electric push rod 15 and the two cylinders 10 based on this information.

[0020] The support frame includes two support legs 8 arranged at one end of the lower side of the mounting plate 3 and arranged at intervals, and a cross bar 9 arranged between the two support legs 8; the two support frames composed of the two support legs 8 and the cross bar 9 support and fix the mounting plate 3.

[0021] Working principle: During the film production process, when it is necessary to install the tube core on the film roll core shaft 21, first, the clamping head 22 at one end of the core shaft 21 is inserted from the upper end opening of the two L-shaped shells 17. During this process, the other end of the core shaft 21 connected to the clamping head 22 will pass through the space between the two L-shaped shells 17, and continue to extend to the other side of the two L-shaped shells 17 and overlap in the supporting arc groove 7. At this time, the limiting bottom plate 18 limits the downward movement of the clamping head 22. Subsequently, the two cylinders 10 are activated through the command of the controller to drive the U-shaped frame 11 to rise, and multiple guides are moved upward. The roller 14 lifts the mandrel 21 upward to a certain height, so that it remains lifted in the supporting arc groove 7 and the two L-shaped shells 17, creating convenient conditions for the subsequent tube core sleeve operation, and also completing the initial fixation of the mandrel 21. Then, the empty tube core is grabbed by the manipulator installed on the frame 1, and the tube core is pushed horizontally through the coordinated action of the linear slide module, the straight cylinder and the sleeve. When the head end of the tube core smoothly passes through one end of the mandrel 21, as it continues to move horizontally, when the tube core passes through the monitoring area of ​​the displacement sensor 20, the displacement sensor The sensor 20 will capture and transmit the monitored position information to the controller. Subsequently, the controller will control the electric push rod 15 and the two cylinders 10 to start according to the information, and drive the U-shaped frame 11 connected to the two cylinders 10 to descend, so that the multiple guide rollers 14 release the support state of the mandrel 21. At the same time, the electric push rod 15 immediately drives the U-shaped support frame 16 to rise until the U-shaped support frame 16 supports one end of the mandrel 21, and the mandrel support mechanism supports the other end of the mandrel 21, thereby preventing the clamping head 22 from being located in the two L-shaped shells 17. The tube core 21 is lowered as it continues to move. When it reaches the multiple guide rollers 14, the multiple guide rollers 14 provide support and guidance for the movement of the tube core, ensuring that the tube core can be smoothly inserted into the core shaft 21, thus completing the tube core insertion operation. The device solves the problem that the core shaft 21 is inconvenient to fix and easy to roll during the current tube core insertion process. It can not only support and fix the core shaft 21, while ensuring that the head end of the tube core can be accurately inserted to one end of the core shaft 21, but also provides continuous and stable support and guidance for subsequent tube insertion operations, thereby improving production efficiency.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
