Technical Field

[0001] This utility model proposes a tube material conveying mechanism, which belongs to the field of paper tube conveying structure. Background Technology

[0002] The current automatic feeding structure in paper tube processing requires manual assistance from workers. Moreover, paper tubes are prone to jamming during the feeding process. Furthermore, the existing feeding structure has high requirements for paper tubes and cannot feed bent paper tubes, requiring manual cleaning, which significantly reduces production efficiency and increases labor costs. There is a need for an automatic feeding and conveying mechanism that is suitable for bent paper tubes. Utility Model Content

[0003] To address the technical problems existing in the prior art, this utility model proposes a tube conveying mechanism that enables automatic feeding of bent paper tubes, reduces tube jamming, and improves production efficiency. The technical features adopted are as follows:

[0004] A material conveying mechanism includes a storage section, a transfer section, and a pusher section. The storage section includes a front main board, a rear main board, left and right stop sheet metal, a base plate, and inclined baffles. The inclined baffles are fixed on the left and right stop sheet metal and tilt downwards towards the transfer section. The inclined baffles are provided with a feeding port that matches the size of the transfer section. The transfer section is provided with baffles on both sides, and the baffles are flush with the driven chain of the transfer section.

[0005] The material transfer section includes a drive motor fixed on the bottom plate of the storage section, a driven shaft and a feeding shaft fixed on the left and right stop sheet metal. The driven shaft is connected to the feeding shaft sprocket through a driven chain. The outer chain plate of the driven chain has a right-angle bent plate with a preset screw hole. The right-angle bent plate is fixed to the material bar chain plate by bolts. The material bar chain plate is a 90-145° angled clamp plate, which is composed of continuous stop bars and spaced stop plates.

[0006] The pushing part includes a front material groove that mates with the top of the material bar chain plate. Tube baffles are provided on both sides of the front groove. The front material groove is inclined and aligned with the pushing groove. A retaining strip is provided on the pushing groove. A pushing structure is provided at the lower end of the pushing groove.

[0007] Preferably, the storage section has pre-drilled mounting holes for connection with the material transfer section and the material pusher section.

[0008] Preferably, the ramp baffle has an angle of 8 to 15° with the horizontal plane.

[0009] Preferably, the drive motor is connected to a reducer, a torque limiter, and a drive shaft, and the drive shaft is connected to the driven shaft sprocket via a drive chain.

[0010] Preferably, the material chain plate has an angle of 20 to 30° with the horizontal plane.

[0011] Preferably, the pusher groove includes a rear main board and a limiting baffle with reinforcing ribs. The limiting baffle is connected to the left and right baffle sheet metal bolts through the reinforcing ribs, and the top of the limiting baffle is connected to the card holder strip with bolts.

[0012] Preferably, the card holder has a long, rigid structure with an arc-shaped groove at the part that contacts the pipe. The radius of curvature of the groove is 1 / 2 of the outer diameter of the pipe, and the depth of the groove is 1 / 3 to 1 / 2 of the outer diameter of the pipe.

[0013] Preferably, the pushing structure includes a transverse lead screw fixed between the rear main plates, a servo motor movably connected to the transverse lead screw, and a strip push rod mounted on the servo motor.

[0014] The beneficial effects of this utility model are as follows:

[0015] The enclosed structure of the storage section prevents the pipe material from rolling off, the inclined baffle guides the pipe material to flow in a specific direction, the size of the feeding port is matched to achieve orderly feeding, and the baffle plate is flush with the driven chain to prevent the pipe material from shifting laterally, thus avoiding pipe jamming and improving feeding stability.

[0016] The angle design of the feeder chain plate enables the conveying of curved tubes. The right-angle bend plate and the feeder chain plate can be adjusted by installation interval to accommodate tubes of different specifications. In addition, it can improve the assembly strength of the chain plate and adapt to the impact force of tube conveying. Furthermore, the baffles on the feeder chain plate reduce the weight of the feeder chain plate and reduce the chain load while ensuring normal paper roll transport. The baffles also improve the utilization rate of production materials.

[0035] Example 1

[0036] Figure 1 , Figure 2 As shown, this utility model is a pipe material conveying mechanism, which includes a storage section 1, a conveying section 2, and a pushing section 3. The storage section includes a front main plate 11, a rear main plate 12, left and right baffle sheet metal 13 and 14, a bottom plate 15, and a ramp baffle 16 assembled to form a closed storage space. The ramp baffle 16 is fixed to the inside of the left and right baffle sheet metal by bolts. The ramp baffle plate is inclined downward at a preset angle and precisely aligned with the conveying section. The contact end between the ramp baffle and the conveying section has a feeding port of matching size to ensure that the pipe material can slide into the conveying section in an orderly manner. The inclined surfaces of the baffle plates 17 on both sides of the conveying section are flush with the driven chain 24 to form a lateral limit. The closed structure design of the storage section 1 prevents the pipe material from rolling off. The ramp baffle guides the pipe material to flow in a directional manner. The matching size of the feeding port enables orderly feeding. The baffle plate being flush with the driven chain prevents the pipe material from shifting laterally, improves feeding stability, and solves the problem of material jamming at the connection of the conveying mechanism.

[0037] like Figure 1 , Figure 3 As shown, the material transfer unit 2 includes a drive motor 21 fixed to a motor mounting base on the bottom plate 15 of the storage unit by bolts. A driven shaft 22 and a feeding shaft 23 are horizontally fixed in preset shaft holes in the left and right stop sheet metals 13 and 14 via bearing seats. A sprocket at the end of the driven shaft 22 meshes with a driven chain 24. A right-angle bent plate 25 with preset screw holes is riveted to the outer chain plate of the driven chain. The right-angle bent plate is detachably connected to the material bar chain plate 26 by bolts. The material bar chain plate adopts a 90-145° angled clamping plate structure. The new type uses a 90° angle and consists of continuous baffles 261 and spacer baffles 262. The right-angle bends are bolted together to improve the assembly strength of the chain plates and adapt to the impact force of pipe material conveying. The baffles and baffles of the angled clamps work together to ensure support while reducing the weight of the material chain plates, reducing the chain load, and improving the utilization rate of the material chain plate production materials. In addition, the right-angle bends and material chain plates can be adjusted by installation interval to accommodate different specifications of pipe materials. Furthermore, it can also improve the assembly strength of the chain plates and adapt to the impact force of pipe material conveying.

[0038] like Figure 4 As shown, the pushing part 3 includes a front material trough 31 and two tube baffles 32 on both sides to form a guide trough. The inlet end of the front material trough 31 is connected to the material chain plate 26 at the top of the material transfer part 2. The trough is tilted as a whole and aligned with the pushing trough 33. Several parallel card holders 34 are installed at the bottom of the pushing trough 33. The lower end of the trough is equipped with a pushing structure 35 that can drive the tube to move.

[0039] The inclined front feed trough 41 of the pusher section 3 enables smooth transition of the tube material, and the tube material baffle prevents lateral slippage; the card holder strip accurately positions the tube material, and the pusher structure ensures that the tube material moves along the preset path, improving the pushing accuracy.

[0040] Example 2

[0041] This embodiment is a further supplement to embodiment 1. Multiple sets of mounting holes 18 are pre-set on the edges of the front main board 11, rear main board 12 and left and right baffle sheet metal 13 and 14 of the material storage section 2. The bearing seat of the material transfer section and the connecting flange of the material push section are connected to the mounting holes by bolts to realize the detachable fixation of the three. The mounting holes are compatible with various specifications of components, improving the versatility and maintenance efficiency of the equipment.

[0042] The ramp baffle 16 has an angle of 8-15° with the horizontal plane. The tilt angle of the ramp baffle is calibrated by laser measurement to ensure it is within the range of 8-15°. In this embodiment, the tilt angle is 8°. The specific angle can be adjusted according to the weight of the pipe material. A smaller angle is used for heavy pipe materials to avoid excessively fast descent; a larger angle is used for light pipe materials to prevent stagnation. The precise angle design balances the descent speed and impact force of the pipe material, ensuring continuous feeding while reducing wear on the material conveying part and extending the equipment life.

[0043] The drive motor 21 is connected to a reducer, a torque limiter, and a drive shaft 27. It is connected to the sprocket of the driven shaft 22 via a drive chain 28. The output shaft of the drive motor is connected to the reducer, the torque limiter, and the drive shaft 27 in sequence via a coupling. The reducer's reduction ratio is adapted to the conveying speed, and the torque limiter has a preset maximum torque threshold. The drive sprocket at the end of the drive shaft 27 and the sprocket of the driven shaft 22 are driven by the drive chain. The reducer achieves low-speed, high-torque output, which is suitable for pipe material conveying requirements. The torque limiter automatically slips when overloaded, protecting the motor and transmission components and reducing the probability of failure.

[0044] The material chain plate 26 has an angle of 20-30° with the horizontal plane, and 20° in this invention. The material chain plate 26 forms an inclination angle of 20-30° by adjusting the height difference between the driven shaft 22 and the feeding shaft. The chain plate maintains this inclination angle to push the pipe material during operation. The reasonable inclination angle realizes the lifting and conveying of the pipe material in a limited space, solves the problem of easy slippage of the pipe material and low conveying efficiency, takes into account both conveying efficiency and pipe material stability, and reduces the floor space.

[0045] Example 3

[0046] This embodiment is a further supplement to Embodiment 2, such as... Figure 2 , Figure 4As shown, the pusher groove 33 includes a rear main board 12 and a limiting baffle 37 with reinforcing ribs 36. The limiting baffle 37 is connected to the left and right baffle sheet metal bolts through the reinforcing ribs 36. The top of the limiting baffle 37 is bolted to the card holder strip 34. The reinforcing ribs improve the deformation resistance of the limiting baffle and strengthen the connection strength between the limiting baffle 37 and the rear main board 12. The bolt connection ensures that the card holder strip is firmly installed and ensures the structural stability of the pusher process.

[0047] The card holder 34 is a long, rigid structure that can be replaced according to the tube material being processed. The part of the card holder 34 that contacts the tube material has an arc-shaped groove with a radius of curvature of 1 / 2 of the outer diameter of the tube material. The depth of the groove covers 1 / 3 to 1 / 2 of the outer diameter of the tube material. The arc-shaped groove fully fits the tube material, improving friction and positioning accuracy. The groove depth design ensures stable support and facilitates subsequent gripping by the robotic arm, while avoiding scratching the surface of the tube material.

[0048] like Figure 5 As shown, the feeding structure 35 includes a transverse lead screw 351 fixed between the rear main plates 12, a servo motor 352 movably connected to the transverse lead screw, and a strip push rod 353 mounted on the servo motor 352. The transverse lead screw 351 is horizontally fixed between the rear main plates 12 through bearing seats at both ends. The lead screw nut is rigidly connected to the mounting seat of the servo motor. The motor output shaft is connected to the strip push rod through a coupling. The length of the push rod matches the width of the feeding groove. The motor receives a PLC control signal to drive the push rod to move along the lead screw axis.

[0049] The workflow of this embodiment is as follows: After the tube is placed into the storage section 1, the tube rolls left and right towards the inlet by gravity. The conveying section 2 rotates, and the tube is transported upward by the material chain plate 26. After reaching the top, the tube leaves the material chain plate and rolls into the pushing section 3. It falls into the pushing groove after being restricted by the front material trough and the tube baffle path. Then, the servo motor drives the strip push rod on the transverse lead screw to complete the pushing and conveying of the tube.

The methods or software programs involved in the debugging and control of the control device and sensors are all based on existing methods or software program design books, manuals or product manuals by those skilled in the art, combined with the functions involved in the principles and effects of this utility model, and can be implemented by writing their own programs.

[0051] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
