Description

Technical Field

[0001] This utility model relates to the field of paper tube processing technology, and in particular to an automatic feeding mechanism for paper tube slitting. Background Technology

[0002] With the rapid development of industries such as packaging, textiles, and printing, the demand for paper tubes, as a core consumable, has exploded. Traditional paper tube slitting relies on manual feeding, which suffers from low efficiency, insufficient precision, and safety hazards, making it difficult to meet the needs of large-scale industrial production. Furthermore, due to human factors, feeding speed and precision are difficult to guarantee, easily leading to deviations in paper tube slitting dimensions and affecting product quality. On the other hand, existing automatic feeding mechanisms mostly use simple mechanical transmission methods, such as chain and belt conveyors, which have poor adaptability to paper tubes of different lengths. Changing paper tube specifications requires a lot of time for equipment adjustment. At the same time, during the feeding process, paper tubes are prone to rolling, deviation, and other unstable phenomena, resulting in inaccurate slitting positions and even equipment failure. Utility Model Content

[0003] In order to overcome the shortcomings of poor adaptability of the existing technology, the technical problem of this utility model is to provide an automatic feeding mechanism for cutting paper tubes that can quickly adapt to paper tubes of different lengths.

[0004] The technical solution of this utility model is as follows: an automatic feeding mechanism for paper tube slitting, including a mounting base, a bracket fixedly connected to the right side of the mounting base, a fixed frame fixedly connected to the left side of the mounting base, a groove provided in the right side of the mounting base, a sliding frame slidably connected to the groove in the mounting base, a feeding cylinder fixedly connected to the fixed frame, and an adjustable feeding cylinder fixedly connected to the sliding frame. When the adjustable feeding cylinder is moved left and right by rotating the screw, the adjustable feeding cylinder is fixed on the sliding frame, so that the sliding frame slides synchronously in the groove of the mounting base, thereby realizing the adjustment of the position of the adjustable feeding cylinder. In this process, the sliding frame provides stable support for the adjustable feeding cylinder. A limiting groove is fixedly connected to the mounting base, and a paper tube is slidably connected to the limiting groove. A sliding groove is fixedly connected to the front of the mounting base. A motor is fixedly connected to the left side of the mounting base. A threaded rod is rotatably connected within the slide groove. The right end of the threaded rod is rotatably connected to the slide groove via a bearing. The left end of the threaded rod is fixedly connected to the motor output shaft via a key, ensuring stable power transmission from the motor to the threaded rod. A push block is threadedly connected to the left side of the threaded rod. The front part of the push block is slidably connected within the slide groove, and the right part of the push block is slidably connected within a limiting groove. A limiting block is fixedly connected to the left side of the mounting base. A sliding rod is slidably connected to the limiting block. A tension spring is sleeved between the limiting block and the sliding rod. The left end of the tension spring is fixedly connected to the sliding rod, and the right end of the tension spring is fixedly connected to the limiting block. The tension spring is used to drive the sliding rod to slide to the right, thereby locking the paper tube and preventing it from falling.

[0005] More preferably, it also includes a fixed block a, which is fixedly connected to the front side of the feeding cylinder and a fixed block b is fixedly connected to the front side of the adjustable cylinder. The left end of a lead screw is rotatably connected to the front part of the fixed block a, and a lead screw is threadedly connected to the front part of the fixed block b. A handle is fixedly connected to one end of the lead screw. When the handle is rotated, the lead screw drives the adjustable cylinder to move left and right through the threaded engagement with the fixed block b, thereby adjusting the distance between the adjustable cylinder and the feeding cylinder to accommodate the placement of paper tubes of different lengths.

[0006] More preferably, it also includes a feeding hopper, and both the feeding cylinder and the adjustable cylinder are fixedly connected to the feeding hopper, which facilitates the insertion of the paper tube.

[0007] More preferably, it also includes an observation window, with an observation window fixedly connected to the front side of both the feeding cylinder and the adjustable cylinder, which facilitates observation of the storage status of the internal paper tubes.

[0008] More preferably, it also includes a limiting wheel, which is rotatably connected to the bracket.

[0009] More preferably, it also includes an anti-slip pad, with the bottom of the mounting base fixedly connected to the anti-slip pad.

[0010] The beneficial effects of this utility model are: by adjusting the spacing with a lead screw to quickly adapt to paper tubes of different lengths, the paper tube falls into the limiting groove through the feeding cylinder, the motor drives the threaded rod to drive the pushing block to move along the slide groove to push the paper tube, the limiting block, the sliding rod and the tension spring work together to realize automatic feeding, the limiting wheel prevents the paper tube from deviating, and the coordinated operation of all components realizes automatic and accurate feeding of paper tubes, thereby improving production efficiency.

[0011] By turning the handle, the lead screw is driven to rotate. When the lead screw rotates, it drives the fixed block b and the adjustable material cylinder to slide left or right according to the length of the paper cylinder via the sliding frame on the mounting base, which plays the role of adjusting the feeding cylinder and achieves the effect of convenient adjustment.

[0012] The feeding hopper installed on the feeding cylinder and the adjustable cylinder facilitates feeding and increases feeding efficiency. Attached Figure Description

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example: An automatic feeding mechanism for paper tube slitting, such as... Figure 1-4As shown, the system includes a mounting base 1, a bracket 101, a fixed frame 2, a sliding frame 201, a feeding cylinder 3, an adjustable feeding cylinder 301, a limiting groove 4, a paper tube 401, a sliding groove 5, a motor 6, a threaded rod 7, a pushing block 8, a limiting block 9, a sliding rod 10, and a tension spring 11. The bracket 101 is fixedly connected to the right side of the mounting base 1, and the fixed frame 2 is fixedly connected to the left side of the mounting base 1. The right side of the mounting base 1 has a groove, and the sliding frame 201 is slidably connected to the groove in the mounting base 1. The feeding cylinder 3 is fixedly connected to the fixed frame 2, and the adjustable feeding cylinder 301 is fixedly connected to the sliding frame 201. When the adjustable feeding cylinder 301 is moved left and right by rotating the screw 13, the adjustable feeding cylinder 301 is fixed to the sliding frame 201, so that the sliding frame 201 slides synchronously in the groove of the mounting base 1. The limiting groove 4 is fixedly connected to the mounting base 1. The paper tube 401 is slidably connected to the limiting groove 4. The sliding groove 5 is fixedly connected to the front of the mounting base 1. The motor 6 is fixedly connected to the left side of the mounting base 1. The threaded rod 7 is rotatably connected to the sliding groove 5. The right end of the threaded rod 7 is rotatably connected to the sliding groove 5 through a bearing. The left end of the threaded rod 7 is fixedly connected to the output shaft of the motor 6 through a key. The push block 8 is threadedly connected to the left side of the threaded rod 7. The front part of the push block 8 is slidably connected to the sliding groove 5. The right part of the push block 8 is slidably connected to the limiting groove 4. The limiting block 9 is fixedly connected to the left side of the mounting base 1. The sliding rod 10 is slidably connected to the limiting block 9. The tension spring 11 is sleeved between the limiting block 9 and the sliding rod 10. The left end of the tension spring 11 is fixedly connected to the sliding rod 10. The right end of the tension spring 11 is fixedly connected to the limiting block 9. It also includes a fixing block a12, a fixing block b1201, the lead screw 13, and a handle 14. The fixing block a12 is fixedly connected to the front side of the feeding cylinder 3, and the fixing block b1201 is fixedly connected to the front side of the adjustable feeding cylinder 301. The left end of the lead screw 13 is rotatably connected to the front part of the fixing block a12, and the lead screw 13 is threadedly connected to the front part of the fixing block b1201. One end of the lead screw 13 is fixedly connected to the handle 14. It also includes a feeding hopper 15, which is fixedly connected to both the feeding cylinder 3 and the adjustable feeding cylinder 301. The feeding hopper 15 facilitates the insertion of the paper tube 401. It also includes an observation window 16, which is fixedly connected to the front side of both the feeding cylinder 3 and the adjustable feeding cylinder 301. The observation window 16 facilitates the observation of the storage status of the paper tube 401 inside.

[0020] After the paper tube 401 is placed into the feeding cylinder 3 and the adjustable cylinder 301, the paper tube 401 slides down the cylinder wall into the limiting groove 4 under the action of gravity. Since the inner wall of the limiting groove 4 is provided with a guide slope, the paper tube 401 can be automatically arranged neatly. After the motor 6 is started, the output shaft drives the threaded rod 7 to rotate. The threaded rod 7 drives the pushing block 8 to slide to the left along the slide groove 5 through the threaded transmission. The right part of the pushing block 8 contacts the paper tube 401 in the limiting groove 4, and the rubber buffer surface provides a smooth push to move the paper tube 401 to the left to the cutting area. When the pushing block 8 slides to the left to push the paper tube 401, the pushing block 8 moves to the left to release its obstruction of the sliding rod 10. The tension spring 11 contracts, causing the sliding rod 10 to slide to the left, so that the locking block at the end of the sliding rod 10 is embedded in the locking groove of the limiting groove 4, locking the subsequent paper tube 401 to fall. When the pushing block 8 completes the push and returns to the initial position, the pushing block 8 moves to the right to squeeze the sliding rod 10, causing the tension spring 11 to stretch. The sliding rod 10 slides to the right and disengages from the locking groove. After the paper tube 401 in the previous stage is pushed, the next paper tube 401 falls into the limiting groove 4 under the action of gravity, realizing automatic feeding cycle. When it is necessary to adjust the position of the adjustable material cylinder 301 to adapt to paper tubes 401 of different lengths, the operator rotates the handle 14 to drive the lead screw 13 to rotate. The lead screw 13 is threaded into the fixed block b1201, and the movement distance of the adjustable material cylinder 301 can be precisely controlled by calculating the number of rotations. After adjustment, the adjustable material cylinder 301 can be fixed on the sliding frame 201 by tightening the locking nut at the end of the lead screw 13 or by setting a positioning pin, ensuring stable position during feeding. An anti-slip pad 18 is also included, and the bottom of the mounting base 1 is fixedly connected to the anti-slip pad 18.

[0021] like Figure 1 As shown, it also includes a limiting wheel 17, which is rotatably connected to the bracket 101.

[0022] Two sets of limiting wheels 17 are symmetrically mounted on the bracket 101, with their axes perpendicular to the conveying direction of the paper tube 401. When the paper tube 401 is fed to the cutting area by the pushing block 8, both sides of the paper tube 401 contact the limiting wheels 17. The limiting wheels 17 restrict the lateral movement of the paper tube 401 through rolling friction, ensuring that the paper tube 401 enters the cutting station along a predetermined trajectory, thereby improving cutting accuracy. The anti-slip pad 18 at the bottom of the mounting base 1 is made of high-friction coefficient rubber. By increasing the friction with the worktable surface, it effectively prevents the feeding mechanism from vibrating and displacing during the starting and stopping of the motor 6 and the pushing of the paper tube 401, ensuring the stability of the entire feeding system.

[0023] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
