Description

Technical Field

[0001] This application belongs to the field of paper production technology, specifically relating to a traction roller for paper production. Background Technology

[0002] In the paper production process, paper needs to be transferred and processed between different devices. To ensure stable tension on the paper and to precisely control the paper feed speed to adapt to different paper characteristics and production requirements, traction rollers are usually installed between devices to provide stable traction force and ensure the flatness, dimensional accuracy, and printing quality of the produced paper.

[0003] In the prior art, the traction roller includes an upper cylinder and a lower cylinder respectively disposed on the upper and lower sides of the paper. When it is necessary to apply traction force to the paper, by adjusting the distance between the upper cylinder and the lower cylinder and driving the upper cylinder and the lower cylinder to rotate in opposite directions, the paper can make contact with the cylinder and generate friction force, thereby driving the paper to move forward.

[0004] After prolonged use, the traction roller requires cleaning and maintenance. The inventors discovered that during the removal of the traction roller, there is a tendency for interference between the existing traction roller and the paper. Typically, cutting the paper is required to avoid its impact on the roller removal process. However, this act of cutting the paper can negatively affect subsequent production steps, leading to a technical problem of reduced paper production efficiency. Utility Model Content

[0005] This application provides a traction roller for paper production, which aims to quickly remove and install the roller without cutting the paper, so as to avoid affecting the paper production process and ensure the paper production efficiency.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A traction roller for paper production is provided, comprising:

[0008] A base is used to fix it to the lower side of the paper translation area; the upper side of the base has a positioning platform, and the positioning platform is connected to the base through an adjustable support structure; and the positioning platform has an upwardly extending positioning shaft.

[0009] Two mounting plates are arranged side-by-side on the upper side of the positioning platform in a vertical direction; each mounting plate has a through-hole in a vertical direction, into which the positioning shaft is inserted to allow the mounting plate to swing about the positioning shaft; furthermore, each mounting plate is rotatably connected to a roller, and the roller is driven by a rotation drive component; and

[0010] A locking structure is provided on the positioning platform for connecting with the two mounting plates to limit the swing of the mounting plates relative to the positioning platform and to ensure that the two rollers are arranged parallel to each other on the upper and lower sides of the paper.

[0011] In one possible implementation, the locking structure includes:

[0012] Two through holes are respectively opened on the two mounting plates, and both are through in the vertical direction; when the two rollers are in a parallel state, the two through holes are coaxially connected.

[0013] A slot, formed on the upper side of the positioning platform, and adapted to communicate with the through hole; and

[0014] A stop bar, adapted to be inserted into two interconnected through holes and into a slot, to limit the swing of each of the mounting plates relative to the positioning stage.

[0015] In one possible implementation, the upper end of the positioning shaft has a horizontally extending abutment plate; the abutment plate is used to abut against the upper side of the mounting plate to prevent the mounting plate from disengaging from the positioning shaft;

[0016] The stop plate has a pre-drilled hole that runs vertically through the stop rod.

[0017] In one possible implementation, the lower side of the actuating plate has a limiting clip adapted to engage with the stop rod;

[0018] When the two mounting plates are joined together, and the lower mounting plate abuts against the upper side of the positioning platform, the limiting card can fill the gap between the upper mounting plate and the blocking plate to restrict the mounting plate from moving upward.

[0019] In one possible implementation, a recessed groove coaxially arranged with the alignment hole is provided on the adjacent side of each of the two mounting plates; a spring is provided between the two mounting plates, which is arranged around the outer periphery of the positioning shaft, and the two ends of the spring are respectively embedded in the two recessed grooves and respectively abut against the bottom of the two recessed grooves.

[0020] When the limiting card is connected to the stop rod, and the upper and lower sides of the limiting card abut against the stop plate and the mounting plate respectively, the spring is in an elastic compression state.

[0021] In one possible implementation, a support pad is detachably connected to the upper side of the positioning stage; the support pad is made of an elastic material so that it can undergo elastic deformation when it comes into contact with the roller located below.

[0022] In one possible implementation, the adjustable support structure includes:

[0023] A support base is fixedly disposed on the upper side of the base; a guide groove is provided on the upper side of the support base, and the support base has a plurality of limiting holes spaced apart in the vertical direction; each of the limiting holes penetrates the support base in the horizontal direction and communicates with the guide groove.

[0024] A connecting post is fixedly disposed on the lower side of the positioning platform and slidably inserted into the guide groove; the connecting post is provided with a horizontally penetrating docking hole, the docking hole being adapted to communicate with any one of the limiting holes; and

[0025] A limiting rod is inserted into the interconnected docking hole and the limiting hole to restrict the relative movement of the support base and the connecting column.

[0026] In one possible implementation, one end of the limiting rod has a protrusion adapted to abut against the outer side of the support base, and the other end of the limiting rod has a through hole extending in the vertical direction, and an L-shaped locking member that is slidably inserted into the through hole.

[0027] When the locking member is inserted into the through hole, the locking member is adapted to abut against the side of the support seat opposite to the protrusion to restrict the movement of the limiting rod.

[0028] In one possible implementation, the rotation drive component is a rotating motor fixedly mounted on the side of the mounting plate facing away from the roller;

[0029] The power output shaft of the rotating motor is coaxially arranged with the drum and is connected in transmission.

[0030] In one possible implementation, a plurality of rollers are fixedly disposed on the lower side of the base, and the base further includes:

[0031] Two support legs are hinged to opposite sides of the base to allow them to swing until their swing ends are supported on the ground.

[0032] When the outriggers are supported on the ground, the swing end faces of the two outriggers are coplanar and both are located below each of the rollers.

[0033] In this embodiment, the base serves to support other components and fix the position of the device. Based on this, by controlling the adjustable support structure to adaptively adjust the height of the positioning platform, the two rollers can be positioned on the upper and lower sides of the paper respectively. Thus, when the two rotating drive components drive the two rollers to rotate, the two rollers can rotate in opposite directions to transmit traction force through friction with the paper, causing the paper to move.

[0034] When the rollers need to be replaced, the locking structure can be released, allowing both mounting plates to swing relative to the positioning table. This causes the two rollers to swing away from the paper, thus preventing the paper from interfering with the removal and installation of the rollers.

[0035] The traction roller for paper production provided in this embodiment, compared with the prior art, can be quickly disassembled and installed without cutting the paper, so as to avoid affecting the paper production steps and ensure the paper production efficiency. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0052] Please refer to the following: Figures 1 to 10 The traction roller 10 for paper production provided in this application will now be described. The traction roller 10 for paper production proposed in this application includes a base 1, two mounting plates 2 and a locking structure 3.

[0053] The base 1 is used to fix it to the lower side of the paper translation area.

[0054] The base 1 has a positioning platform 4 on its upper side. This positioning platform 4 is also located below the translation area of ​​the paper material and is connected to the base 1 through an adjustable support structure 5. In this embodiment, the height of the positioning platform 4 can be changed through the adjustable support structure 5 to adapt to the translation of the paper material at different heights.

[0055] The positioning platform 4 has an upwardly extending positioning shaft 41; two mounting plates 2 are arranged side by side on the upper side of the positioning platform 4 in the vertical direction; each mounting plate 2 has a through-hole 21 in the vertical direction, and the aforementioned positioning shaft 41 is inserted into the through-hole 21 to realize the swing connection between the mounting plate 2 and the positioning platform 4, so that the mounting plate 2 can swing relative to the positioning platform 4 with the positioning shaft 41 as the axis.

[0056] In this embodiment, each mounting plate 2 is rotatably connected to a roller 10, and this roller 10 is driven by a rotation drive component 101. Under the action of gravity, the two mounting plates 2 will overlap together, so that the outer peripheral walls of the two rollers 10 respectively abut against the upper and lower sides of the paper.

[0057] The locking structure 3 is set on the positioning table 4 and is used to connect with the two mounting plates 2 to limit the swing of the mounting plates 2 relative to the positioning table 4 and to make the two rollers 10 parallel to each other on the upper and lower sides of the paper.

[0058] In this embodiment, the base 1 serves to support other components and fix the position of the device. Based on this, by controlling the adjustable support structure 5 to adaptively adjust the height of the positioning platform 4, the two rollers 10 can be positioned on the upper and lower sides of the paper respectively. Thus, when the two rotation drive components 101 drive the two rollers 10 to rotate, the two rollers 10 can rotate in opposite directions to transmit traction force through friction with the paper, causing the paper to move.

[0059] When it is necessary to replace the roller 10, by releasing the locking structure 3, both mounting plates 2 can swing relative to the positioning table 4, thereby causing the two rollers 10 to swing to a position away from the paper, so as to avoid the paper interfering with the removal and installation of the roller 10.

[0060] Compared with the prior art, the traction roller 10 for paper production provided in this embodiment can be quickly disassembled and installed without cutting the paper, so as to avoid affecting the paper production steps and ensure the paper production efficiency.

[0061] In some embodiments, such as Figure 9 As shown, the locking structure 3 includes two through holes 31, a slot 32, and a stop rod 33.

[0062] Two through holes 31 are respectively opened on two mounting plates 2, and both are through in the vertical direction; when the two rollers 10 are in a parallel state, the two through holes 31 are coaxially connected.

[0063] The slot 32 is provided on the upper side of the positioning table 4 and is adapted to communicate with the through hole 31; when the mounting plate 2 swings to the position where it communicates with the corresponding through hole 31 and slot 32, the corresponding roller 10 is axially parallel to the width direction of the paper so that the roller 10 can act on the process of pulling the paper.

[0064] The stop bar 33 is adapted to be inserted into two interconnected through holes 31, and its lower end is also inserted into a slot 32 to limit the swing of each mounting plate 2 relative to the positioning stage 4.

[0065] In some embodiments, such as Figures 1 to 4 As shown, the upper end of the positioning shaft 41 has a stop plate 42 extending in the horizontal direction; this stop plate 42 is used to abut against the upper side of the mounting plate 2 to prevent the mounting plate 2 from disengaging from the positioning shaft 41.

[0066] The stop plate 42 has a reserved hole 421 that runs through the vertical direction and is suitable for the stop rod 33 to pass through; the upper end of the stop rod 33 has a suspension part suitable for abutting against the upper side of the stop plate 42 to ensure the relative position of the stop rod 33 and the stop plate 42.

[0067] In some embodiments, such as Figure 3 and Figure 4 As shown, the lower side of the stop plate 42 has a limiting clip 331 suitable for engaging with the stop rod 33; in this embodiment, the limiting clip 331 adopts a C-shaped structure with an opening size corresponding to the width of the stop rod 33, so as to be suitable for engaging with the outer periphery of the stop rod 33.

[0068] By adopting the above technical solution, when the two mounting plates 2 are connected and the mounting plate 2 located on the lower side abuts against the upper side of the positioning table 4, the limiting card 331 can fill the gap between the mounting plate 2 located on the upper side and the blocking plate 42 to restrict the upward movement of the mounting plate 2, ensuring the relative position of the two mounting plates 2 and the corresponding two rollers 10 respectively contacting the upper and lower sides of the paper.

[0069] In some embodiments, such as Figure 5 and Figure 10 As shown, each of the two mounting plates 2 has a recessed groove 22 coaxially arranged with the alignment hole 21 on its adjacent side; between the two mounting plates 2 there is a spring 6 arranged around the outer periphery of the positioning shaft 41, and the two ends of the spring 6 are respectively embedded in the two recessed grooves 22 and respectively abut against the bottom of the two recessed grooves 22.

[0070] When the limit card 331 is connected to the stop rod 33, and the upper and lower sides of the limit card 331 abut against the stop plate 42 and the mounting plate 2 respectively, the spring 6 is in an elastic compressed state. Correspondingly, after the limit card 331 is removed, the mounting plate 2 located on the upper side will move upward a certain distance under the action of the spring 6, so as to facilitate manual control of the swing of the mounting plate 2.

[0071] In some embodiments, such as Figure 3 As shown, a support pad 43 is detachably connected to the upper side of the positioning platform 4.

[0072] In this embodiment, the support pad 43 is made of an elastic material so that when the support pad 43 comes into contact with the roller 10 on the lower side, the support pad 43 can undergo elastic deformation, thereby providing a stable support effect for the roller 10 and preventing loosening between the two rollers 10.

[0073] In some embodiments, such as Figure 3 and Figure 6 As shown, the adjustable support structure 5 includes a support base 51, a connecting column 52, and a limiting rod 53.

[0074] The support base 51 is fixedly installed on the upper side of the base 1; the upper side of the support base 51 is provided with a guide groove 511, and the support base 51 has a plurality of limiting holes 512 spaced apart in the vertical direction; wherein, each limiting hole 512 penetrates the support base 51 in the horizontal direction and communicates with the guide groove 511.

[0075] The connecting post 52 is fixedly installed on the lower side of the positioning platform 4 and is slidably inserted into the guide groove 511. The connecting post 52 is provided with a horizontally penetrating docking hole 521. As the connecting post 52 moves synchronously to adjust the height of the positioning platform 4, this docking hole 521 can communicate with any of the limiting holes 512.

[0076] The limiting rod 53 is inserted into the interconnected mating hole 521 and limiting hole 512 to restrict the relative movement of the support base 51 and the connecting column 52; and since the axes of the mating hole 521 and the limiting hole 512 are both horizontal, the limiting rod 53 can be stably in the inserted state.

[0077] In some embodiments, such as Figure 1 and Figure 7 As shown, one end of the limiting rod 53 has a protrusion 531 suitable for abutting against the outer side of the support base 51, and the other end of the limiting rod 53 has a through hole 532 extending in the vertical direction, and an L-shaped locking member 533 that is slidably inserted into the through hole 532.

[0078] By adopting the above technical solution, when the locking member 533 is inserted into the through hole 532, the locking member 533 is adapted to abut against the side of the support base 51 facing away from the protrusion 531, so as to restrict the movement of the limiting rod 53.

[0079] In some embodiments, such as Figure 1 , Figure 2 and Figure 8 As shown, the rotation drive component 101 is a rotating motor fixedly mounted on the side of the mounting plate 2 facing away from the roller 10; specifically, this rotating motor is realized by means of multiple connecting rods arranged around it.

[0080] In this embodiment, the power output shaft of the rotating motor is coaxially arranged with the roller 10 and is connected in transmission. Based on this, when it is necessary to replace the roller 10, the roller 10 can be pulled out simply by disconnecting the rotating motor and the roller 10, thereby further ensuring the quickness of roller 10 installation and removal.

[0081] In some embodiments, such as Figures 1 to 3 As shown, multiple rollers 11 are fixedly installed on the lower side of the base 1 to enable the base 1 to slide on the ground, facilitating the movement of the device between different workstations. In addition, the base 1 also includes two support legs 12, which are respectively hinged to opposite sides of the base 1 to be adapted to swing to an angle where their swing ends are supported on the ground or to avoid the ground.

[0082] When the support leg 12 is supported on the ground, the swing end faces of the two support legs 12 are coplanar and are both located under each roller 11, so as to release the contact between the roller 11 and the ground and ensure the stable arrangement of the base 1.

[0083] The above content is only 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.
