Description

Technical Field

[0001] This application relates to the field of paper tube edge grinding equipment technology, and in particular to an edge grinding dust removal device for a paper winding machine. Background Technology

[0002] A paper winding machine is an important piece of equipment in the papermaking process. It is mainly used to wind the paper produced in the previous stage onto a paper tube and roll it into a paper roll.

[0003] When the aforementioned paper winding machine winds the paper, the uneven ends of the paper tube make the paper prone to wrinkling during the winding process. Therefore, the ends of the paper tube need to be ground before winding. This grinding process typically involves a motor driving a grinding disc to smooth the ends of the paper tube.

[0004] During the edge grinding process of the paper tube, a large amount of paper scraps will be generated. Due to the static electricity generated during the friction process, the paper scraps will be attracted to the paper tube, causing bulges and wrinkles when the paper is wound up, which will cause great inconvenience to the paper winding. Summary of the Invention

[0005] To facilitate paper winding, this application provides a grinding and dust removal device for a paper winding machine.

[0006] This application provides a dust removal device for edge grinding of a paper rolling machine, which adopts the following technical solution:

[0007] A dust removal device for edge grinding of a paper winding machine includes a housing, a fixing component, a driving component, and a clamping component. One side of the housing is open, and two grinding discs are slidably connected to the housing. Fixing rods are inserted into the two grinding discs. The fixing component is located inside the housing and is used to fix a paper tube to the fixing rods. The driving component is located inside the housing and is used to drive the fixing rods to rotate. The clamping component is located inside the housing and is used to ensure that the grinding discs are always in contact with the paper tube during edge grinding.

[0008] By adopting the above technical solution, when grinding the edges of the paper tube, the paper tube is fixed on the fixed rod by the fixing component, and then the paper tube and the fixed rod are driven to rotate by the driving component. During the rotation, the two grinding discs are always in contact with the two ends of the paper tube by the clamping component, so that the paper tube and the grinding discs rotate relative to each other and the edges of the paper tube are ground.

[0009] Compared to the traditional edge grinding method where the paper tube is fixed and the grinding disc rotates, the method of grinding the paper tube by fixing the grinding disc and rotating the paper tube results in paper scraps falling onto the paper tube surface during the rotation of the paper tube. Under the action of centrifugal force, these scraps move away from the paper tube, thus avoiding paper scraps adhering to the paper tube and facilitating subsequent paper winding.

[0010] Optionally, two sets of clamping assemblies are provided, each corresponding to one of the grinding discs. Each clamping assembly includes a clamping telescopic rod and a clamping spring. The fixed end of the clamping telescopic rod is fixedly connected to the housing, and the movable end of the clamping telescopic rod is fixedly connected to the grinding disc. The movable end of the clamping telescopic rod divides the interior of the fixed end of the clamping telescopic rod into a first rod-side cavity and a first rodless cavity. The clamping spring is fixedly disposed in the first rodless cavity and is in a compressed state.

[0011] By adopting the above technical solution, when grinding the paper tube, the operator pushes one of the grinding discs to slide away from the other grinding disc, thereby causing the clamping telescopic rod to retract. Then, the operator puts the paper tube on the fixed rod and releases the grinding disc. Since the clamping spring is always in a compressed state, the clamping telescopic rod extends, pushing the grinding disc to abut against the paper tube.

[0012] During the edge grinding process, as the grinding progresses, the length of the paper tube gradually shortens. Under the action of the compression spring, the compression telescopic rod is pushed to continue to extend, so that the grinding disc is always in contact with the paper tube. There is no need for the operator to manually adjust the position of the paper tube, so that the paper tube and the grinding disc are always in contact, thus facilitating the edge grinding of the paper tube.

[0013] Optionally, the fixing assembly includes a double-ended telescopic rod, a fixing spring, a first connecting pipe, an elastic element, and a second connecting pipe; the fixed end of the double-ended telescopic rod is fixedly disposed inside the fixing rod, and the two movable ends of the double-ended telescopic rod are slidably connected to the fixing rod; the two movable ends of the double-ended telescopic rod divide the interior of the fixed end of the double-ended telescopic rod into two second rod-containing chambers and a second rodless chamber; two fixing springs are provided, each corresponding to one of the second rod-containing chambers, and the fixing springs are fixedly disposed inside the second rod-containing chambers; the two ends of the first connecting pipe are respectively connected to the second rodless chamber and the first rod-containing chamber, and liquid is pre-filled in the second rodless chamber, the first rod-containing chamber, and the first connecting pipe; the elastic element is fixedly disposed inside the housing, and the elastic element has a cavity structure; the two ends of the second connecting pipe are respectively connected to the interior of the elastic element and the first connecting pipe, and liquid is pre-filled in the interior of the elastic element and the second connecting pipe; an overflow valve is fixedly installed on the second connecting pipe.

[0014] By adopting the above technical solution, when grinding the paper tube, the operator pushes one of the grinding discs to slide away from the other grinding disc, thereby causing the clamping telescopic rod to retract. The liquid in the second rodless chamber flows into the first rod chamber, causing the two movable ends of the double-headed telescopic rod to retract, avoiding interference with the movable ends of the double-headed telescopic rod when the paper tube is put on the fixed rod, thus facilitating the grinding of the paper tube.

[0015] After the paper tube is fitted onto the fixed rod, the operator releases the grinding disc. Under the action of the compression spring, the telescopic rod is compressed and extended, causing the liquid in the first rod chamber to be squeezed into the second rodless chamber. This pushes the two movable ends of the double-headed telescopic rod to extend until they abut against the inner wall of the paper tube, thus fixing the paper tube to the fixed rod.

[0016] When the drive assembly rotates the fixed rod, the two movable ends of the double-headed telescopic rod slide away from the fixed end of the double-headed telescopic rod under the action of centrifugal force, thereby further increasing the fixing force on the paper tube.

[0017] During the edge grinding process, as the grinding proceeds, the length of the paper tube gradually shortens. Under the action of the compression spring, the compression telescopic rod extends. However, at this time, the liquid in the second rodless chamber is full, so the liquid in the first rod chamber enters the elastic element, allowing the compression telescopic rod to continue to extend and press the grinding disc.

[0018] Optionally, one end of the first connecting pipe near the second rodless cavity is coaxially inserted inside the fixed rod and rotatably connected to the fixed rod; the first connecting pipe is rotatably connected to the fixed end of the double-headed telescopic rod.

[0019] By adopting the above technical solution, during the edge grinding process, the first connecting tube will not rotate with the rotation of the fixed rod, but will remain in a fixed state, thus preventing the first connecting tube from getting tangled on the fixed rod and preventing the first connecting tube from being worn when the fixed rod rotates.

[0020] Optionally, the drive assembly includes a motor and a rotating shaft; the motor is fixedly installed inside the housing, and the output shaft of the motor is coaxially arranged with the fixing rod; both ends of the rotating shaft are coaxially fixedly connected to the output shaft of the motor and the fixing rod, respectively.

[0021] By adopting the above technical solution, when grinding the edges of the paper tube, the operator starts the motor, which drives the rotating shaft to rotate, thereby driving the fixed rod and the paper tube to rotate.

[0022] Optionally, a vacuum head is provided inside the box, which is connected to a vacuuming device and is used to suck up paper scraps and dust inside the box.

[0023] By adopting the above technical solution, the dust collection head is always in working condition during the edge grinding process, collecting paper scraps inside the box to prevent them from adhering to the paper tube during the subsequent paper tube removal process, thus facilitating the subsequent paper winding.

[0024] Optionally, a sliding sleeve is inserted into the grinding disc, and the sliding sleeve is fixedly connected to the grinding disc; both ends of the fixing rod are inserted into the sliding sleeve.

[0025] By adopting the above technical solution, the fixed rod can rotate smoothly and the grinding disc can slide relative to the fixed rod, while also preventing the fixed rod from being worn by the grinding disc.

[0026] Optionally, a protective door is provided at the opening of the box; the protective door is hinged to the box.

[0027] By adopting the above technical solution, the protective door can be closed during edge grinding to prevent paper scraps from flying out and requiring operators to clean them up, thus making it easier to use.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By setting up a drive component, compared with the traditional edge grinding method of fixing the paper tube and rotating the grinding disc, the paper tube is ground by fixing the grinding disc and rotating the paper tube. When the paper tube rotates, the paper scraps generated by the edge grinding fall onto the surface of the paper tube and move away from the paper tube under the action of centrifugal force, thereby avoiding the paper scraps adhering to the paper tube, which facilitates the subsequent paper winding.

[0030] 2. By setting up a clamping component, during the edge grinding process, the length of the paper tube gradually shortens as the edge grinding proceeds. Under the action of the clamping spring, the clamping telescopic rod is pushed to continue to extend, so that the grinding disc is always in contact with the paper tube. There is no need for the operator to manually adjust the position of the paper tube, so that the paper tube and the grinding disc are always in contact, thus facilitating the edge grinding of the paper tube.

[0031] 3. By setting up a fixing component, after the paper tube is fitted onto the fixing rod, the operator releases the grinding disc. Under the action of the compression spring, the telescopic rod is pressed and extended, pushing the two movable ends of the double-headed telescopic rod to extend until they abut against the inner wall of the paper tube, thereby fixing the paper tube to the fixing rod. In the initial state, the two movable ends of the double-headed telescopic rod are retracted to avoid interference with the movable ends of the double-headed telescopic rod when the paper tube is fitted onto the fixing rod, thus facilitating the edge grinding of the paper tube.

[0032] 4. By setting up an elastic element, during the edge grinding process, as the edge grinding proceeds, the length of the paper tube gradually shortens. Under the action of the compression spring, the compression telescopic rod extends. However, at this time, the liquid in the second rodless chamber is full, so the liquid in the first rod chamber enters the elastic element, allowing the compression telescopic rod to still extend and press the grinding disc.

[0044] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0045] This application discloses an edge grinding and dust removal device for a paper rolling machine. (Refer to...) Figure 1 The dust removal device for the edge grinding of the paper roll machine includes a housing 1, a fixing assembly 2, a driving assembly 3, and a pressing assembly 4. The housing 1 is horizontally positioned, with an opening on one side. A protective door 7 is installed at the opening of the housing 1. The top of the protective door 7 is hinged to the housing 1, and the hinge axis is horizontal. The protective door 7 is made of transparent material. A handle is fixedly installed on the protective door 7.

[0046] Reference Figure 2 Two grinding discs 11 are fixedly installed inside the housing 1, and the two grinding discs 11 are arranged in parallel. A slider is fixedly installed at the bottom of the grinding disc 11. A groove is opened on the bottom wall of the housing 1, and the slider is located in the groove and slidably connected to the housing 1. A sliding sleeve 6 is inserted into the grinding disc 11 and is fixedly connected to the grinding disc 11. A fixing rod 12 is coaxially inserted inside the sliding sleeve 6.

[0047] Reference Figure 2Two sets of clamping components 4 are provided, each corresponding to a grinding disc 11. Each clamping component 4 includes a clamping telescopic rod 41 and a clamping spring 42. The clamping telescopic rod 41 is horizontally positioned inside the housing 1, with its fixed end fixedly connected to the bottom wall of the housing 1, and its movable end fixedly connected to the side of the grinding disc 11 furthest from the other grinding disc 11. The movable end of the clamping telescopic rod 41 divides the interior of its fixed end into a first rod-side cavity 411 and a first rodless cavity 412, with the first rod-side cavity 411 located between the first rodless cavity 412 and the grinding disc 11. The clamping spring 42 is horizontally positioned inside the first rodless cavity 412, with both ends fixedly connected to the movable end and the fixed end of the clamping telescopic rod 41, respectively, and is always in a compressed state.

[0048] When grinding the paper tube, the operator pulls the handle to open the protective door 7 by rotating it upwards. Then, one of the grinding discs 11 is pushed to slide away from the other grinding disc 11, which causes the clamping telescopic rod 41 to continue to compress the clamping spring 42 and retract it. Then, the operator puts the paper tube on the fixed rod 12 and releases the grinding disc 11. Under the action of the clamping spring 42, the clamping telescopic rod 41 extends, thereby pushing the grinding disc 11 to abut against the paper tube. During the grinding process, as the grinding progresses, the length of the paper tube gradually shortens. Since the clamping spring 42 is always in a compressed state, it pushes the grinding disc 11 to always abut against the paper tube.

[0049] Reference Figure 2 and Figure 3 The fixing assembly 2 includes a double-headed telescopic rod 21, a fixing spring 22, and a first connecting pipe 23. The fixed end of the double-headed telescopic rod 21 is vertically disposed inside the fixing rod 12 and fixedly connected to it. Both movable ends of the double-headed telescopic rod 21 are slidably connected to the fixing rod 12, and their sliding axes are coaxial with the axis of the double-headed telescopic rod 21. The two movable ends of the double-headed telescopic rod 21 divide the interior of the fixed end of the double-headed telescopic rod 21 into two second rod-containing chambers 211 and a second rodless chamber 212, with the second rodless chamber 212 located between the two second rod-containing chambers 211. Two fixing springs 22 are provided, corresponding one-to-one with the second rod-containing chambers 211. The fixing springs 22 are disposed within the second rod-containing chambers 211, and their two ends are fixedly connected to the movable end and the fixed end of the double-headed telescopic rod 21, respectively. The elastic force of the compression spring 42 is greater than the elastic force of the fixing spring 22.

[0050] Reference Figure 2 and Figure 3One end of the first connecting pipe 23 is vertically inserted into the fixed end of the pressing telescopic rod 41 and communicates with the inside of the first rod-side cavity 411. The other end of the first connecting pipe 23 is horizontally inserted into the fixed rod 12 and is rotatably connected to the fixed rod 12. The end of the first connecting pipe 23 located inside the fixed rod 12 communicates with the inside of the second rodless cavity 212. The first connecting pipe 23 is rotatably connected to the fixed end of the double-headed telescopic rod 21. Liquid is pre-filled in the second rodless cavity 212, the first rod-side cavity 411, and the first connecting pipe 23.

[0051] Reference Figure 2 The elastic element 24 is fixedly installed on the inner wall of the housing 1, and the elastic element 24 has a hollow structure. The two ends of the second connecting pipe 25 are respectively connected to the inside of the elastic element 24 and the first connecting pipe 23. Liquid is pre-filled in both the inside of the elastic element 24 and the second connecting pipe 25. An overflow valve 251 is fixedly installed on the second connecting pipe 25, and the starting pressure of the overflow valve 251 is greater than the elastic force of the fixed spring 22.

[0052] Initially, due to the presence of liquid in the second rodless cavity 212, the two movable ends of the double-headed telescopic rod 21 are extended. When the operator pushes the grinding disc 11 to slide away from the other grinding disc 11, causing the compression telescopic rod 41 to retract, the volume of the first rod cavity 411 increases. Under the action of the fixing spring 22, the liquid in the second rodless cavity 212 flows into the first rod cavity 411 through the first connecting pipe 23, causing the two movable ends of the double-headed telescopic rod 21 to retract. After the operator places the paper tube on the fixing rod 12, they release the grinding disc 11. Under the action of the compression spring 42, the compression telescopic rod 41 extends, causing the liquid in the first rod cavity 411 to be squeezed and flow into the second rodless cavity 212 through the first connecting pipe 23, thereby pushing the two movable ends of the double-headed telescopic rod 21 to extend until they abut against the inner wall of the paper tube, thus fixing the paper tube to the fixing rod 12.

[0053] During the edge grinding process, as the grinding progresses, the length of the paper tube gradually shortens. Since the compression spring 42 is always in a compressed state, it pushes the compression telescopic rod 41 to extend, thereby pushing the grinding disc 11 to always be in contact with the paper tube. At this time, the liquid in the second rodless chamber 212 is in a full state. Therefore, when the volume in the first rod chamber 411 decreases, the liquid in the first rod chamber 411 enters the elastic element 24 through the first connecting pipe 23 and the second connecting pipe 25, causing the elastic element 24 to be in an expanded state.

[0054] After the edge grinding is completed, the operator pushes the grinding disc 11 to slide away from the other grinding disc 11, thereby causing the clamping telescopic rod 41 to retract. The volume in the first rod cavity 411 increases. Under the elastic force of the fixed spring 22 and the elastic element 24, the liquid in the elastic element 24 and the liquid in the second rodless cavity 212 flow back to the first rod cavity 411 through the first connecting pipe 23 and the second connecting pipe 25. The operator then removes the paper tube and can proceed with the edge grinding operation of the next paper tube.

[0055] Reference Figure 2 The drive assembly 3 includes a rotating shaft 32 and a motor 31. The rotating shaft 32 is coaxially and fixedly connected to the fixed rod 12. The motor 31 is located inside the housing 1 and is fixedly connected to the side wall of the housing 1. The output shaft of the motor 31 is coaxially and fixedly connected to the rotating shaft 32.

[0056] After the paper tube is fixed to the fixing rod 12, the operator pulls the handle to make the protective door 7 rotate downward and close. Then, the motor 31 is started. The motor 31 drives the rotating shaft 32 to rotate, thereby driving the fixing rod 12 and the paper tube to rotate. The two ends of the paper tube rotate relative to the grinding disc 11, thereby grinding the edges of the paper tube.

[0057] When the motor 31 drives the fixed rod 12 to rotate, the two movable ends of the double-headed telescopic rod 21 slide away from the fixed end of the double-headed telescopic rod 21 under the action of centrifugal force, thereby further increasing the fixing force on the paper tube.

[0058] When the paper tube rotates and is edged, under the action of centrifugal force, the paper scraps adsorbed on the surface of the paper tube due to electrostatic effect move away from the paper tube, thereby avoiding the paper scraps adhering to the paper tube.

[0059] Reference Figure 2 A vacuum head 5 is fixedly installed on the top of the box 1. The vacuum head 5 is connected to a vacuuming device and is used to suck up paper scraps and dust inside the box 1.

[0060] During the edge grinding process, the dust suction head 5 is in working condition, sucking up the paper scraps and dust flying inside the box 1, so as to prevent them from adhering to the paper tube during the subsequent removal of the paper tube.

[0061] The implementation principle of the edge grinding and dust removal device for a paper rolling machine according to an embodiment of this application is as follows:

[0062] When grinding the edges of the paper tube, the operator pulls the handle to rotate the protective door 7 upwards and open it. This pushes one of the grinding discs 11 to slide away from the other grinding disc 11, causing the compression telescopic rod 41 to continue compressing the compression spring 42, which in turn increases the volume of the first rod chamber 411. Liquid in the second rodless chamber 212 flows into the first rod chamber 411 through the first connecting pipe 23, causing the two movable ends of the double-headed telescopic rod 21 to retract.

[0063] The operator then places the paper tube onto the fixed rod 12, releases the grinding disc 11, and, under the action of the compression spring 42, compresses the extension rod 41, causing the liquid in the first rod-side chamber 411 to be squeezed and flow through the first connecting pipe 23 into the second rodless chamber 212. This pushes the two movable ends of the double-headed extension rod 21 to extend until they abut against the inner wall of the paper tube, thus fixing the paper tube to the fixed rod 12. The compression of the extension rod 41 further pushes the grinding disc 11 against the paper tube.

[0064] After the paper tube is fixed to the fixing rod 12, the operator pulls the handle to make the protective door 7 rotate downward and close. Then, the motor 31 is started. The motor 31 drives the rotating shaft 32 to rotate, thereby driving the fixing rod 12 and the paper tube to rotate. The two ends of the paper tube rotate relative to the grinding disc 11, thereby grinding the edges of the paper tube.

[0065] During the edge grinding process, as the grinding progresses, the length of the paper tube gradually shortens. Since the compression spring 42 is always in a compressed state, it pushes the compression telescopic rod 41 to continue extending, and the grinding disc 11 remains in contact with the paper tube. At this time, the liquid in the second rodless chamber 212 is full. Therefore, when the volume in the first rod chamber 411 decreases, the liquid in the first rod chamber 411 enters the elastic element 24 through the first connecting pipe 23 and the second connecting pipe 25.

[0066] When the paper tube rotates and is edged, under the action of centrifugal force, the paper scraps adsorbed on the surface of the paper tube due to electrostatic effect move away from the paper tube, thereby preventing paper scraps from adhering to the paper tube. At the same time, the dust suction head 5 is in working condition, sucking up the flying paper scraps and dust inside the box 1.

[0067] After the edge grinding is completed, the operator pulls the handle to rotate the protective door 7 upward and open it. Then, the operator pushes the grinding disc 11 to slide away from the other grinding disc 11, thereby causing the pressing telescopic rod 41 to retract. The volume in the first rod cavity 411 increases. Under the elastic force of the fixed spring 22 and the elastic element 24, the liquid in the elastic element 24 and the liquid in the second rodless cavity 212 flow back to the first rod cavity 411 through the first connecting pipe 23 and the second connecting pipe 25. The operator then removes the paper tube and can proceed with the edge grinding operation of the next paper tube.

[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
