Description

Technical Field

[0001] This utility model relates to the field of paper tube conveying and drying technology, and in particular to a paper tube conveying device with drying function. Background Technology

[0002] Most paper tube conveying devices on the market currently only have a single conveying function and lack a mechanism to dry the small amount of moisture in the paper tubes. To achieve paper tube drying, companies typically need to install separate drying equipment outside the conveyor line. The paper tubes must first be transported to the drying equipment via a conveyor, dried, and then transferred to the next process via another conveyor. This method not only increases the equipment footprint and production costs but also makes the production process cumbersome due to multiple transfers, reducing overall production efficiency. Therefore, developing a conveying device that can simultaneously achieve efficient and uniform drying during the conveying process has significant practical significance and application value.

[0003] Most existing drying boxes in conveyor systems are fixed and stationary, and the air outlets are restricted to a downward orientation. This means that when removing, cleaning, or replacing the electric heating element, one must insert their head into the limited and cramped space between the drying box and the conveyor belt to inspect and locate the positioning components (such as screws) of the electric heating element. A wrench or other disassembly tools must be used to calibrate and align the positioning components. Furthermore, one must insert their hand into the cramped space to loosen and disassemble the positioning components using the disassembly tools. These limitations of the cramped space make the removal and replacement of the electric heating element quite cumbersome and inconvenient. Utility Model Content

[0004] In view of this, the present invention provides a paper tube conveying device with drying function to solve the problem that the disassembly and removal of electric heating tubes is troublesome and inconvenient.

[0005] The technical solution proposed by this utility model is as follows: a paper tube conveying device with drying function, specifically including two symmetrically arranged vertical support plates and a conveyor belt, with a drying box rotatably arranged above the middle part of the conveyor belt; two rotating shafts are symmetrically welded to the outer sides of the two short side walls of the drying box, and the two rotating shafts are respectively connected to the two vertical support plates through a rotating engagement; a drive lever is welded to the outer periphery of the first end of one rotating shaft; a positioning insert is slidably installed on the outer side of one of the vertical support plates in the form of a spring push; a positioning hole is opened through one rotating shaft, and the positioning insert is inserted into the positioning hole.

[0006] Furthermore, an electric heating tube with a continuous S-shaped meandering structure is fixedly installed inside the drying oven; Four T-shaped fixing blocks are symmetrically welded on the two outermost horizontal tube sections of the electric heating tube, and the T-shaped fixing blocks are fixedly connected to the short side wall of the drying oven. A ceramic fiber gasket is pressed and fixed between the T-shaped fixing block and the short side wall of the drying oven.

[0007] Furthermore, two fans connected to the top of the drying chamber are fixedly installed.

[0008] Furthermore, it also includes three U-shaped supports arranged at equal intervals, with a bearing frame welded to the top of each of the three U-shaped supports, a horizontal bearing plate welded to the top of the bearing frame, and two drive rollers symmetrically rotated and installed in the space adjacent to both ends of the bearing frame.

[0009] Furthermore, conveyor belts are fitted on both drive rollers, and a drive assembly is fixedly installed on the top part of a U-shaped bracket on the outer side. The power output shaft of the drive assembly is connected to the roller shaft of the corresponding drive roller through a coupling. An electrical control box is fixedly installed on a vertical side plate of the U-shaped bracket.

[0010] Furthermore, the top ends of the two vertical side rods of the central U-shaped bracket are symmetrically fixed with two vertical support plates.

[0011] Furthermore, multiple longitudinal baffles are evenly distributed on the conveyor belt, and the paper tubes to be dried are placed in the conveying placement grooves formed between every two adjacent longitudinal baffles. The top layer of the conveyor belt is in close contact with the support frame, and the bottom layer is located below the support frame; The top of the two long side bars of the load-bearing frame are symmetrically welded with two horizontal guardrails, and the longitudinal baffle and the top layer of the conveyor belt are located between the two horizontal guardrails.

[0012] The paper tube conveying device with drying function provided by this utility model has the following beneficial effects: The drying oven is installed by rotation, allowing it to be flipped upside down. This flips the bottom air outlet upwards, exposing the internal heating elements and the T-shaped fixing blocks that secure them. This facilitates the removal of the T-shaped fixing blocks for easy disassembly, cleaning, or replacement of the heating elements. Compared to existing technologies that use a fixed, static installation, this avoids the drying oven's air outlet being permanently confined to a downward-facing position. It eliminates the cumbersome and time-consuming process of inserting one's head into the limited space between the heating elements and the conveyor belt to locate the T-shaped fixing blocks, align the fixing bolts and wrench, and loosen the bolts by reaching into the confined space. This design removes the obstacles and limitations imposed by the limited space on heating element disassembly, making the process more convenient and efficient. Attached Figure Description

[0022] Implementation 2: This embodiment is based on Implementation 1, but with the following additions: It also includes three equally spaced U-shaped supports 1, with a bearing frame 9 welded to the top of each of the three U-shaped supports 1. A horizontal bearing plate 901 is welded to the top of the bearing frame 9. Two drive rollers 6 are symmetrically rotated and installed in the space adjacent to both ends of the bearing frame 9. A conveyor belt 2 is fitted on the two drive rollers 6. A drive assembly 5 is fixedly installed on the top part of the outer U-shaped support 1. The power output shaft of the drive assembly 5 is connected to the roller shaft of the corresponding side drive roller 6 through a coupling. An electrical control box 4 is fixedly installed on a vertical side plate of the U-shaped support 1. The drive assembly 5 is integrally formed by the motor and the reducer.

[0023] Preferably, the top ends of the two vertical side rods of the central U-shaped bracket 1 are symmetrically fixed with two vertical support plates 101.

[0024] Preferably, multiple longitudinal baffles 201 are evenly distributed on the conveyor belt 2, and the paper tubes 3 to be dried are placed in the conveying placement grooves formed between every two adjacent longitudinal baffles 201; the top layer of the conveyor belt 2 is in close contact with the support frame 9, and the bottom layer is located below the support frame 9; two transverse baffles 902 are symmetrically welded to the top of the two long side bars of the support frame 9, and the longitudinal baffles 201 and the top layer of the conveyor belt 2 are located between the two transverse baffles 902.

[0025] Preferably, the electrical control box 4 is equipped with an electrical control unit that controls the start and stop of the drive assembly 5, the fan 8, and the electric heating tube 702.

[0026] The working principle, specific details, implementation steps, functions and interrelationships of the features in the above embodiments, and the roles these features play in realizing this technical solution will be described and explained in detail below: The input and output ends of conveyor belt 2 should be equipped with a material conveying device and a material unloading device (not shown in the figure) located above and below conveyor belt 2, respectively. Before use, the blower 8 and the electric heating tube 702 should be turned on. During use, the material conveying device first conveys the paper tube 3 processed in the previous process to the input end of conveyor belt 2. Then, conveyor belt 2 conveys the paper tube 3 to its output end. During this process, when the paper tube 3 is conveyed through the space below the drying box 7, it is blown and dried by the blowing drying unit composed of blower 8 and electric heating tube 702 to remove the small amount of moisture contained therein. After drying and dehydration, the paper tube 3 is conveyed to the output end of conveyor belt 2 and falls onto the material unloading device, which continues to convey it to the next process.

[0027] During long-term use, the surface of the heating element 702 will accumulate a large amount of fuzzy or other impurities due to the continuous blowing of the fan 8. These impurities will accumulate on the surface of the heating element and hinder the radiation and dissipation of heat from the heating element 702, thus affecting the drying effect of the blowing and drying unit on the paper tube 3. Therefore, it is necessary to regularly remove and clean the heating element 702.

[0028] The drying oven 7 is rotatably installed, allowing it to be flipped upside down. This flips the bottom air outlet upwards, exposing the internal heating element 702 and the T-shaped fixing block 7021 that secures it to the air outlet. This facilitates the removal of the T-shaped fixing block 7021 for disassembly, cleaning, or repair / replacement of the heating element 702. Compared to existing technologies that use a fixed, static installation for the drying oven 7, this avoids the air outlet being permanently confined to a downward-facing position, saving time and effort in the process of cleaning and repairing the heating element. When the heating element 702 is disassembled, cleaned, or replaced, it is necessary to insert one's head into the limited and cramped space between the heating element 702 and the conveyor belt 2 to check and locate the T-shaped fixing block 7021, and to calibrate and align the fixing bolts and wrench on the T-shaped fixing block 7021. In addition, it is necessary to insert one's hand into the above-mentioned cramped space to hold the wrench and loosen the bolts. This is a troublesome and cumbersome step. Removing the above-mentioned cramped space from the disassembly operation of the heating element 702 makes the disassembly operation of the heating element 702 more convenient and efficient.

[0029] When the positioning rod 1012 is inserted into the positioning hole 7012, the positioning shaft 701 can be inserted to keep the drying box 7 in the working state after the flip adjustment. When the air outlet of the drying box 7 is flipped downward, it is directly opposite the paper tube 3 and is used to dry the paper tube 3. When the air outlet of the drying box 7 is flipped upward, it is used to disassemble the heating tube 702. When the drying box 7 is flipped and adjusted, the positioning shaft 701 must be pulled away from the positioning hole 7012 and the positioning shaft 701 must be loosened.

[0030] It is worth noting that the composition of the electrical control unit, its connection and wiring method with the motor, fan 8 and electric heating tube 702, and its control principle for the motor, fan 8 and electric heating tube 702 are existing technologies for those skilled in the art who are engaged in the design, modification, upgrading and testing of equipment electrification, and therefore will not be described in detail here.

[0031] The following points should be noted in this article: 1. The accompanying drawings of this utility model embodiment only involve the structures involved in this utility model embodiment; other structures can refer to general designs.

[0032] 2. Where there is no conflict, the embodiments of this utility model and the features in the embodiments can be combined with each other to obtain new embodiments.

[0033] The above are merely specific embodiments 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 scope of the claims.
