Description

Technical Field

[0001] This application relates to the field of material feeding, and in particular to a paper tube feeding device. Background Technology

[0002] Paper tubes are widely used in many industrial sectors, including packaging and printing. With the rapid development of modern industry and the continuous improvement of automation, efficient and precise paper tube delivery has become a key factor in ensuring smooth production processes. Achieving stable paper tube delivery not only greatly enhances the continuity and stability of the production process but also significantly reduces manual labor, thereby improving overall production efficiency and lowering production costs.

[0003] In traditional paper roll pushing operations, a common method involves manual handling and pushing of the paper rolls. Operators rely on their physical strength to move the paper rolls one by one to the designated location. While this method is simple and easy to implement, requiring no complex equipment, it is extremely inefficient and easily affected by the operator's physical strength and skill level. In some cases, ordinary linear push rods are used to push the paper rolls, using the extension and retraction of the push rods to move the paper rolls.

[0004] However, existing technologies cannot automatically push paper tubes into a regular staggered arrangement, nor can they ensure that the paper tubes are in the set position before pushing them, which greatly limits the improvement of production efficiency and quality. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this application provides a paper tube pushing device that accurately positions the paper tube to a set position before pushing it and makes the paper tubes form a regular staggered arrangement after pushing.

[0006] This application is achieved through the following technical solution:

[0007] A paper tube pushing device, comprising:

[0008] The pushing component includes a first pushing plate and a second pushing plate that are horizontally slidably connected to a support frame. The front end of the first pushing plate is provided with a first slot for adapting to a paper tube, and the front end of the second pushing plate is provided with a second slot for adapting to a paper tube. The first slot and the second slot are arranged alternately.

[0009] A drive mechanism is used to provide reciprocating thrust in the horizontal direction to drive the first and second card slots to push the paper tube in a set sequence.

[0010] The limiting component includes a rotating rod rotatably connected above the pushing component, and a limiting frame and a lever are fixed on the rotating rod; the limiting frame is used to limit a number of paper tubes conveyed to the front of the pushing component; the lever can abut against the pushing component under the gravity of the limiting frame.

[0011] When the pushing component moves, it can move a lever to drive the limiting frame to deflect, thereby causing the limiting frame to disengage from the paper tube.

[0012] By adopting the above technical solution, the staggered first and second slots can be provided with horizontal reciprocating thrust by the drive mechanism to ensure that the paper tubes are pushed in the set order, forming a regular staggered arrangement. This not only improves the space utilization rate, but also makes the outer walls of the front and rear rows of paper tubes tangent, making the stacked paper tubes more stable. The limiting frame of the limiting component can limit several paper tubes conveyed to the front of the pushing component. When the pushing component moves, the pushing component drives the lever to deflect, raising the limiting frame to ensure smooth movement of the paper tubes and realize the limiting and release of the paper tubes.

[0013] Optionally, the support frame is provided with a first slide rail, and the first push plate is slidably connected to the first slide rail via a first slider; the first push plate is provided with a second slide rail, and the second push plate is slidably connected to the second slide rail via a second slider.

[0014] By adopting the above technical solution, the slide rail and slider are set so that the first push plate can slide horizontally on the support frame and the second push plate can slide horizontally on the first push plate, realizing the horizontal sliding connection between the components and ensuring that the first push plate and the second push plate can independently push the paper tube in the horizontal direction.

[0015] Optionally, the first and second sliders are dovetail sliders.

[0016] By adopting the above technical solution, the first push plate and the second push plate slide on the first slide rail and the second slide rail respectively through the dovetail slider. The dovetail slider can make the sliding of the push plate more stable, ensuring the stability and reliability of the paper tube pusher.

[0017] Optionally, the driving mechanism includes a first driving motor and a second driving motor; the first driving motor and the second driving motor are respectively used to drive the first push plate and the second push plate to slide back and forth in the horizontal direction in a set order; the output end of the first driving motor is provided with a first gear, and the output end of the second driving motor is provided with a second gear; the first push plate is provided with a first rack adapted to the first gear; the second push plate is provided with a second rack adapted to the second gear.

[0018] By adopting the above technical solution, a first drive motor and a second drive motor are set to drive the first push plate and the second push plate respectively. With the cooperation of gears and racks, the first push plate and the second push plate can slide back and forth in the horizontal direction in a set order, thereby realizing that the first card slot and the second card slot push the paper tube in a set order.

[0019] Optionally, the limiting frame includes a crossbar, which is connected to the rotating rod via a connecting rod. The connecting rod has an "L" shape, and the crossbar is used to prevent the paper tube from shifting.

[0020] By adopting the above technical solution, a limiting frame is formed by connecting the crossbar to the rotating rod via the L-shaped connecting rod. The rotating rod, together with the crossbar and the connecting rod, can limit the paper tube when it is conveyed to the front of the pushing component, thus preventing the paper tube from moving around.

[0021] Optionally, the end of the crossbar is provided with a bend that guides several paper tubes conveyed to the front of the push assembly.

[0022] By adopting the above technical solution, the bent part at the end of the crossbar can guide the paper tube that is conveyed to the front of the pushing component, so that the paper tube can be conveyed to the set position along the preset track.

[0023] Optionally, the rotating rod is provided with a fixing block, and the fixing block has a sliding hole for adjusting the extension length of the connecting rod.

[0024] By adopting the above technical solution and setting an adjustable sliding hole for the extension length of the connecting rod, the extension length and deflection angle of the connecting rod in the limiting frame can be flexibly adjusted, so that the limiting frame can meet the limiting requirements of paper tubes of different heights, adapt to paper tubes of different specifications, and improve the versatility and applicability of the paper tube pushing device.

[0025] Optionally, a guide plate is provided on the side wall of the first push plate, and a pulley is provided at the end of the lever to abut against the guide plate.

[0026] By adopting the above technical solution, when the pushing component moves, the guide plate on the side wall of the first pushing plate abuts against the pulley at the end of the lever, which can more smoothly move the lever, thereby driving the limit frame to deflect and releasing the limit frame from the paper tube. At the same time, it can also reduce friction loss and improve the stability and service life of the device.

[0027] Optionally, the guide plate is provided with an abutment plate that abuts against the pulley.

[0028] By adopting the above technical solution, when the push component moves, the abutment plate set on the guide plate can better abut against the pulley at the end of the lever, providing guidance for the pulley to roll on the guide plate and facilitating the lever to be turned.

[0029] Optionally, the first and second card slots are detachably connected to the first and second push plates.

[0030] By adopting the above technical solution, it is easy to replace the card slots of different specifications to adapt to paper tubes of different specifications, thereby improving the versatility and flexibility of the device.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. This application uses a first push plate and a second push plate arranged in parallel to push paper tubes to a set position in sequence, so that the paper tubes form a regular staggered arrangement, which improves space utilization and the stability of stacked paper tubes;

[0033] 2. This application can prevent paper tube displacement by setting a limiting component, ensuring that the paper tube is in the set position before being pushed, thereby improving production quality;

[0034] 3. This application provides power to the first push plate and the second push plate by means of a first drive motor and a second drive motor respectively, so that the first push plate and the second push plate can move independently and push the paper tube to the set position, thereby improving production efficiency.

[0040] The technical solutions of various embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example

[0041] Reference Figures 1-3 This application discloses a paper tube pushing device, comprising:

[0042] The push assembly 2 includes a first push plate 23 and a second push plate 24 that are horizontally slidably connected to the support frame 1. The front end of the first push plate 23 is provided with a first slot 21 for adapting to the paper tube 5, and the front end of the second push plate 24 is provided with a second slot 22 for adapting to the paper tube 5. The first slot 21 and the second slot 22 are arranged alternately.

[0043] The drive mechanism 3 is used to provide reciprocating thrust in the horizontal direction to drive the first slot 21 and the second slot 22 to push the paper tube 5 in a set sequence;

[0044] The limiting component 4 includes a rotating rod 43 rotatably connected above the pushing component 2. A limiting frame 44 and a lever 47 are fixed on the rotating rod 43. The limiting frame 44 is used to limit the several paper tubes 5 conveyed to the front of the pushing component 2. The lever 47 can abut against the pushing component 2 under the gravity of the limiting frame 44.

[0045] When the push component 2 moves, the push component 2 can move the lever 47 to drive the limit frame 44 to deflect, thereby causing the limit frame 44 to disengage from the limit on the paper tube 5.

[0046] Specifically, refer to Figure 1 The limiting component 4 includes a rotating rod 43 rotatably connected above the pushing component 2. A limiting frame 44 and a lever 47 are fixed on the rotating rod 43. The limiting frame 44 is used to limit the paper tubes 5 conveyed to the front of the pushing component 2. The lever 47 can abut against the pushing component 2 under the gravity of the limiting frame 44. The limiting frame 44 includes a crossbar 45, which is connected to the rotating rod 43 through a connecting rod 46. The connecting rod 46 has an "L" shape. The crossbar 45 is used to prevent the paper tubes 5 from shifting. The end of the crossbar 45 is provided with a bent portion 451 that guides the paper tubes 5 conveyed to the front of the pushing component 2. This bent portion 451 can guide the paper tubes 5, allowing the paper tubes 5 to enter the pushing position more smoothly.

[0047] Reference Figures 1-2The rotating rod 43 is equipped with a fixing block 431, and the fixing block 431 has a sliding hole 432 for adjusting the extension length of the connecting rod 46. By adjusting the extension length of the connecting rod 46, and in conjunction with the lever 47, the deflection angle of the limiting frame 44 can be adjusted. In addition, the first slot 21 and the second slot 22 are detachably connected to the pushing assembly 2, so that the paper tube pushing device can adapt to the limiting requirements of different specifications of paper tubes 5. The first slot 21 and the second slot 22 can be connected by bolts or snap-fits, etc. This detachable connection facilitates the replacement and maintenance of the slots. When the slots are worn or need to be adapted to different specifications of paper tubes 5, the operation can be carried out conveniently.

[0048] Reference Figures 1-3 The driving mechanism 3 provides reciprocating thrust in the horizontal direction to drive the first slot 21 and the second slot 22 to push the paper tube 5 in a set sequence. The driving mechanism 3 includes a first driving motor 31 and a second driving motor 32, which drive the first push plate 23 and the second push plate 24 to slide reciprocally in the horizontal direction in a set sequence. The front end of the first push plate 23 is provided with a first slot 21 adapted to the paper tube 5, and the front end of the second push plate 24 is provided with a second slot 22 adapted to the paper tube 5. The first slot 21 and the second slot 22 are staggered and have an arc-shaped structure, which enables the first push plate 23 and the second push plate 24 to push the paper tube 5 independently and stably under the action of the first driving motor 31 and the second driving motor 32, preventing the paper tube 5 from shifting during the pushing process, and ultimately making the paper tube 5 form a regular staggered arrangement. This arrangement and pushing method not only improves space utilization but also makes the stacked paper tubes 5 more stable. A first gear 33 is provided at the output end of the first drive motor 31, and a second gear 34 is provided at the output end of the second drive motor 32. A first rack 35, which matches the first gear 33, is provided on the first push plate 23, and a second rack 36, which matches the second gear 34, is provided on the second push plate 24. The motor drives the gears to rotate, and the gears mesh with the racks, thus converting the rotational motion of the motor into the linear motion of the push plates. The drive motors here can also be replaced by hydraulic or pneumatic drive devices, as long as they can provide suitable reciprocating thrust.

[0049] Reference Figures 2-3The pushing component 2 includes a first pushing plate 23 and a second pushing plate 24 horizontally slidably connected to the support frame 1. The support frame 1 is provided with a first slide rail 25, and the first pushing plate 23 is slidably connected to the first slide rail 25 via a first slider 251. The first pushing plate 23 is provided with a second slide rail 26, and the second pushing plate 24 is slidably connected to the second slide rail 26 via a second slider 261. The first slider 251 and the second slider 261 are dovetail sliders, which have good guiding properties and stability. Other types of sliders, such as T-shaped sliders, can also be used, as long as they can achieve stable sliding of the first pushing plate 23 on the first slide rail 25. The first slide rail 25 and the second slide rail 26 are arranged in parallel, further improving the stability of the first pushing plate 23 and the second pushing plate 24 pushing the paper tube 5.

[0050] Reference Figure 1 and Figure 4 The first push plate 23 has a guide plate 42 on its side wall, and the end of the lever 47 has a pulley 41 that abuts against the guide plate 42. The pulley 41 reduces the friction between the lever 47 and the guide plate 42, making the lever 47 move more smoothly. The guide plate 42 has an abutment plate 421 that abuts against the pulley 41. The abutment plate 421 increases the contact area, ensuring that the lever 47 can be moved by the first push plate 23. When the push assembly 2 moves, the first push plate 23 moves the lever 47, causing the pulley 41 to slide on the guide plate 42, which in turn causes the lever 47 to deflect. Since the lever 47 is fixedly connected to the rotating rod 43, the rotating rod 43 rotates accordingly, which in turn drives the limiting frame 44 to deflect and raise the limiting frame 44, allowing the pushed paper tube 5 to pass smoothly. In this way, the first slot 21 and the second slot 22 can push the paper tube 5 in a set order, realizing the staggered arrangement of the paper tube 5.

[0051] The implementation principle of this embodiment is as follows: This paper tube pushing device pushes the paper tubes 5 in a set order under the drive of the driving mechanism 3 through the staggered arrangement of the first slot 21 and the second slot 22, thus realizing the staggered arrangement of the paper tubes 5. The limiting component 4 limits the paper tubes 5 before pushing to ensure that the paper tubes 5 are in the set position, and can release the limit in time during pushing so as not to affect the pushing of the paper tubes 5.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this application.
