Description

Technical Field

[0001] This application relates to the field of paper tube processing technology, and more specifically, to a feeding and conveying device for drying paper tubes. Background Technology

[0002] In the paper tube production process, drying is a key step to ensure the quality of the paper tubes. However, existing drying equipment is often too high and generally requires a feeding conveyor to transport the paper tubes into the drying equipment.

[0003] In the existing technology, common feeding and conveying devices often adopt simple conveyor belt or chain structures, which often lack flexible adjustment mechanisms and are difficult to adapt to paper tubes of different sizes. Especially when the diameter changes, frequent adjustments or replacements of parts are required, which increases the complexity and cost of operation.

[0004] Therefore, this application proposes a feeding and conveying device for paper tube drying to solve the above-mentioned technical problems. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] The purpose of this application is to address the shortcomings of the prior art by providing a feeding and conveying device for drying paper tubes, thereby solving the problem that the feeding and conveying devices in the prior art are difficult to flexibly adapt to paper tubes of different sizes.

[0007] To achieve the above objectives, this application provides the following technical solution: A feeding and conveying device for drying paper tubes includes two drive shafts, with drive gears fixed at both ends of the drive shafts. A chain is sleeved between the drive gears at corresponding positions on the two drive shafts, and the two chains form a conveying mechanism. Multiple conveying rods are fixed at equal intervals between the two chains, and multiple support blocks for supporting paper tubes to be dried are installed on the conveying rods. A support groove is opened on the upper end face of the support block, and a movable block is slidably arranged in the support groove. The movable block cooperates with the support groove to form a groove for the paper tubes to be dried to be placed.

[0008] Furthermore, at least three support blocks are fixed at equal intervals on the conveying rod.

[0009] Furthermore, one end of the support block is provided with a slot and is engaged with the conveyor rod.

[0010] Furthermore, a first bolt is provided at the end of the support block, the first bolt extending into the slot and passing through the conveying rod to form a fixation.

[0011] Furthermore, the top side of the movable block is inclined, and the inner side of the support groove is symmetrically inclined with the movable block, forming an inverted "V" shaped groove.

[0012] Furthermore, vertical plates extending downwards and fitting against both sides of the bottom of the movable block are fixed on both sides of the bottom of the block. A second bolt is provided on the vertical plate, and the second bolt abuts against the side wall of the block to form a fixation.

[0013] Furthermore, an oil storage groove is provided at the bottom of the tooth groove of the transmission gear, and an oil storage cotton for accumulating lubricating oil is embedded in the oil storage groove, with one end of the oil storage cotton extending into the tooth groove of the transmission gear.

[0014] The beneficial effects of this application are as follows: In the above solution, by cooperating with the support groove and the movable block, an adjustable groove can be formed on the support block, which can firmly limit paper tubes of different diameters and make it flexible to use; In the above solution, the adjustable design of the support block on the conveyor rod and the cooperation of the oil-storing foam in the transmission gear can continuously self-lubricate the chain, reducing the maintenance frequency.

[0015] In summary, this device can not only transport paper tubes of different specifications, making it flexible in use, but also has a self-lubricating function, extending the durability of the equipment and resulting in good overall performance. Attached Figure Description

It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this application.

[0021] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0022] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0023] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Reference Figure 1-4 As shown, this utility model provides a feeding and conveying device for drying paper tubes, including two parallel drive shafts 1. The drive shafts 1 are made of 45# steel, and drive gears 2 are fixedly installed at both ends by flat keys. A chain 3 is sleeved between the corresponding drive gears 2 on the two drive shafts 1. The chain 3 is a 08B roller chain, forming a synchronously operating conveying mechanism. An oil storage groove 201 is machined at the bottom of the tooth groove of the drive gear 2, and an oil-absorbing cotton 202 is tightly embedded in the groove. The oil-absorbing cotton 202 can be made of high-temperature resistant wool felt material, and its surface is slightly higher than the bottom surface of the tooth groove by about 1 mm, so as to continuously provide lubrication to the chain 3 when the gear rotates.

[0025] Multiple conveyor rods 4 are fixed at equal intervals between the two chains 3. The conveyor rods 4 are fixed to the connecting plate of the chains 3 by hexagonal bolts. Multiple support blocks 5 are installed at equal intervals on each conveyor rod 4. In this embodiment, three support blocks are provided. The support blocks 5 are injection molded from nylon material, and one end of each block has a U-shaped slot 501, which is used to engage with the conveyor rod 4. A first bolt 502 is provided at the end of the support block 5. This bolt is an M6 hexagonal socket head cap bolt, whose threaded end passes through the side wall of the slot 501 and through the conveyor rod 4, and is locked in place with a nut.

[0026] The upper surface of the support block 5 is machined with a horizontal support groove 6, within which a movable block 7 is slidably mounted. One side of the top of the movable block 7 is designed with a 30-degree inclination, forming an inverted V-shaped groove together with the similarly inclined inner wall of the support groove 6. The bottom sides of the movable block 7 have downward-extending vertical plates, with a second bolt 701 (M4 flat-head screw) installed on the outer side of each plate. Tightening the bolts allows the vertical plates to fit tightly against the side wall of the support block 5, thus fixing the movable block 7 in its position within the support groove 6.

[0027] Working principle: In actual operation, the operator first adjusts the spacing of the support block 5 on the conveyor rod 4 according to the length of the paper tube, and then loosens the first bolt 502 to move the support block 5 to the required position. For paper tubes of different diameters, the groove width can be changed by adjusting the position of the movable block 7 in the support groove 6. After adjustment, tightening the second bolt 701 will fix it.

[0028] When the device is running, the transmission gear 2 drives the chain 3 to rotate at a constant speed. The lubricating oil pre-stored in the oil storage cotton 202 is evenly coated on the pin of the chain 3 during gear meshing, forming continuous lubrication. The paper tube is stably placed in the groove formed by the support block 5 and the movable block 7, and enters the drying equipment in sequence as the conveyor rod 4 moves. The entire conveying process is stable and reliable, and can adapt to various paper tubes of different specifications.

[0029] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.

[0030] It should be noted that this application covers any alternatives, modifications, equivalent methods, and solutions made within the spirit and scope of this application. To provide the public with a thorough understanding of this application, specific details are described in detail in the preferred embodiments, while those skilled in the art can fully understand this application without these details. Furthermore, to avoid unnecessary confusion regarding the substance of this application, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0031] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
