Description

Technical Field

[0001] The utility model belongs to the technical field of paper product manufacturing equipment and relates to a paper tube conveyor. Background Art

[0002] The paper tube feeding machine is an important part of the shaft pulling system when the paper machine produces shaft pulling base paper. Its function is to deliver the 20-inch paper tube core to the predetermined position of the shaft puller. The 20-inch paper tube core weighs about 78kg and needs to slide on the circular track (DN100) and be delivered to the inside of the shaft puller lifting platform. During the transportation process, since the paper tube core is in direct contact with the track, the transmission motor drives the tube pusher arm through the belt to push the paper tube core onto the working platform. The sliding friction of the paper tube core is very large due to its own weight, which often causes the coupling and transmission belt of the tube feeding machine transmission mechanism to break.

[0003] Therefore, in order to avoid losses caused by machine damage, the above problems need to be solved urgently. Summary of the invention

[0004] Purpose of the utility model: The purpose of the utility model is to solve the above-mentioned problems and provide a paper tube conveyor.

[0005] Technical solution: The utility model is a paper tube conveyor, comprising a transmission motor, a tube pushing arm and a track. The tube pushing arm is arranged on two parallel tracks and moves along the tracks. The transmission motor drives the tube pushing arm through a belt to push the paper tube core on the track to the working platform. A plurality of mounting holes are respectively arranged on the contact surface between the two tracks and the paper tube core. The mounting holes are equidistant and arranged in a line. Bearings are installed in the mounting holes. The paper tube core is in direct contact with the bearing and moves linearly on the bearing along the track direction.

[0006] Furthermore, the bearing is a bull's eye bearing.

[0007] Furthermore, the diameter of the mounting hole is the same as the diameter of the base of the bearing.

[0008] Furthermore, the spacing between the mounting holes and the corresponding bearings is 0.4-1m, preferably 0.5m. If the distance is too large, the paper tube core will bend, and if the distance is too small, the installed bearings will be too dense, which is not economical. Secondly, if the resistance is too small, the paper tube core will have inertia after movement and exceed the designated location. Thirdly, if there are too many mounting holes, the track strength will be reduced and it will also bend.

[0009] Furthermore, the coverage area of ​​the bearing is not less than the total length of the paper tube core to be transported.

[0010] Furthermore, the number of the mounting holes is 8 to 15, preferably 12.

[0011] Furthermore, the first hole of the mounting hole is located 200-300 mm away from the end point of the track exit, preferably 250 mm, to prevent the paper tube core from sliding out of a designated location.

[0012] Furthermore, the diameter of the mounting hole and the diameter of the bearing base are 24 mm.

[0013] Beneficial effects: Compared with the prior art, the utility model has the following advantages: The utility model reduces resistance by changing the current sliding friction form into rolling friction, thereby reducing the motor load and protecting the equipment. After the track is transformed according to the new technical solution, the friction force is significantly reduced, there is no damage to the coupling, and the operation is very smooth.

[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0020] As attached Figure 1-3 As shown, a paper tube conveyor of the utility model includes a transmission motor 1, a tube pushing arm 3 and a track 3. The tube pushing arm 2 is arranged on two parallel tracks 3 and moves along the track 3. The transmission motor 1 drives the tube pushing arm 2 through a belt to push the paper tube core 5 on the track 3 to the working platform. The pushing direction is shown in the direction of arrow a.

[0021] Take paper tube core (specification: D545mm*L2800mm round tube) and track 3 (D114*L6850mm round tube) as an example. Figure 2 , the traditional paper tube core 5 is in direct contact with the track 3, the transmission motor 1 drives the tube pusher arm 2 through the belt, and the tube pusher arm 2 pushes the paper tube core 5 to the working platform. Since the paper tube core 5 needs to slide on the circular track 3 and be sent to the inside of the shaft puller lifting platform, the sliding friction force is very large during the transportation process, which often causes the coupling and transmission belt of the tube feeder transmission mechanism to break.

[0022] See also Figure 3-4 , by setting a plurality of mounting holes on the contact surface between the two rails 3 and the paper tube core 5, the mounting holes are equidistant and arranged in a straight line, the mounting holes are installed with bearings 4, the diameter of the mounting holes is the same as the diameter of the base of the bearing 4, the number of mounting holes is 8 to 15, the paper tube core 5 is in direct contact with the bearing 4 and moves linearly along the propulsion direction of the rail 3 on the bearing 4. In a specific embodiment, the diameter Φ1 of the rail 3 is 114mm, and 12 circular holes with a diameter of 24mm are drilled on each of the two rails 3. Since the rail 3 can transport at most two paper tube cores 5 at the same time, according to the paper tube core with a specification length of 2800mm, the total transmission length is 5600mm, so the bearing 4 covers an area of ​​not less than 5600mm. In this embodiment, d1=1100mm, d2=5500mm, and d3=250mm. That is, the distance between the first hole position and the end point of the rail exit is 250mm, and they are arranged in a straight line with an equidistant distance of 500mm. Then install the bearing 4 in the installation hole. In this embodiment, the bearing adopts a bull's eye bearing. Specifically, a bull's eye bearing with a base diameter of Φ5 and also 24mm is gently knocked into the installation hole and fixed. The paper tube core 5 is in direct contact with the bull's eye bearing, and the bull's eye bearing is embedded in the circular roller. The paper tube core 5 can make a linear motion along the propulsion direction of the track 3 on the bull's eye bearing. The transmission motor 1 drives the push tube arm 2 through the belt, and the push tube arm 2 pushes the paper tube core 5 to the working platform. Through this improvement, the paper tube core 5 is not in direct contact with the track 3, but in contact with the bull's eye bearing. The bull's eye bearing has a strong load-bearing capacity and low friction. The original sliding friction form is changed to rolling friction, which reduces resistance, thereby reducing the motor load and protecting the equipment.

[0023] like Figure 5 As shown, the specific specifications of the bull's eye bearing are as follows: the diameter Φ2 of the steel ball in contact with the paper tube core 5 of the bull's eye bearing is 15 mm, h1=6 mm, h2=10 mm, h3=21 mm. The diameter of the mounting base is Φ5=24 mm, and the outer diameter is Φ3=31 mm.

[0024] In a specific embodiment, the spacing of the mounting holes is 0.4-1m, that is, the spacing of the bearings 4. If this distance is set too large, the paper tube core 5 will bend. If the distance is too small, the bearings 4 will be too dense, which is not economical. Secondly, if the resistance is too small, the paper tube core 5 will have inertia after movement, so that it will exceed the designated location during transmission. Thirdly, if there are too many mounting holes, the strength of the track 3 will also become low, resulting in bending. Experimental results show that a spacing of 0.5 meters is the most ideal.
