Description

Technical Field

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

[0002] The paper reel is an important equipment in the papermaking process. It is mainly used to reel the paper produced in the previous process onto a paper tube and roll it into a paper roll.

[0003] When the above-mentioned paper reel is used to rewind paper, the uneven ends of the paper tube easily cause wrinkles during the rewinding process. Therefore, the ends of the paper tube need to be edge-grinded before rewinding. When edge-grinding the paper tube, a motor is usually used to drive the grinding disc to rotate and grind the ends of the paper tube flat.

[0004] During the edging process of the paper tube, a large amount of paper scraps are generated. Due to the static electricity generated during the friction process, the paper scraps are adsorbed on the paper tube, causing bulges and wrinkles when the subsequent paper is rolled up, which causes great inconvenience in paper rolling. Summary of the Invention

[0005] In order to facilitate paper winding, the present application provides an edge grinding and dust removal device for a paper winding machine.

[0006] The present application provides a paper winding machine edge grinding and dust removal device, which adopts the following technical solutions: A grinding and dust removal device for a paper winding machine comprises a box body, a fixing assembly, a driving assembly and a pressing assembly; one side of the box body is an open structure, and two grinding discs are arranged inside the box body, and both grinding discs are slidably connected to the box body; a fixing rod is inserted into the two grinding discs; the fixing assembly is arranged inside the box body, and is used to fix a paper tube on the fixing rod; the driving assembly is arranged inside the box body, and is used to drive the fixing rod to rotate; the pressing assembly is arranged inside the box body, and is used to keep the grinding disc and the paper tube in contact at all times when grinding the paper tube.

[0007] By adopting the above technical solution, when grinding the edge of the paper tube, the paper tube is fixed to the fixed rod through the fixing component, and then the driving component is used to drive the paper tube and the fixed rod to rotate. During the rotation process, the two grinding discs are always in contact with the two ends of the paper tube through the clamping component, so that the paper tube and the grinding discs rotate relative to each other, and the two ends of the paper tube are ground.

[0008] Compared with the traditional paper tube fixed grinding disc rotating grinding method, the paper tube is ground by the grinding disc fixed paper tube rotating method. When the paper tube rotates, the paper scraps generated by grinding fall on the surface of the paper tube and move away from the paper tube under the action of centrifugal force, thus avoiding the attachment of paper scraps to the paper tube and facilitating the subsequent paper winding.

[0009] Optionally, the clamping assembly is provided with two groups, and corresponds one to one with the grinding disc, and the clamping assembly includes a clamping telescopic rod and a clamping spring; the fixed end of the clamping telescopic rod is fixedly connected to the box body, 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-containing cavity and a first rodless cavity; the compression spring is fixedly arranged in the first rodless cavity, and the compression spring is in a compressed state.

[0010] By adopting the above technical solution, when grinding the edge of the paper tube, the operator pushes one of the grinding discs to slide away from the other grinding disc, thereby causing the compression telescopic rod to contract. Then the operator puts the paper tube on the fixed rod and releases the grinding disc. Since the compression spring is always in a compressed state, the compression telescopic rod extends, pushing the grinding disc to abut against the paper tube.

[0011] During the edging process, as the edging 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. The operator does not need to manually adjust the position of the paper tube, and the paper tube and the grinding disc can always be in contact, which facilitates the edging of the paper tube.

[0012] Optionally, the fixed assembly includes a double-headed telescopic rod, a fixed spring, a first connecting tube, an elastic member and a second connecting tube; the fixed end of the double-headed telescopic rod is fixedly arranged inside the fixed rod, and the two movable ends of the double-headed telescopic rod are slidably connected to the fixed rod; the two movable ends of the double-headed telescopic rod divide the interior of the fixed end of the double-headed telescopic rod into two second rod-containing cavities and a second rodless cavity; there are two fixing springs, and they correspond one-to-one to the second rod-containing cavities, and the fixing spring is fixed in the second rod-containing cavity; the two ends of the first connecting tube are respectively connected with the second rodless cavity and the first rod-containing cavity, and liquid is preset in the second rodless cavity, the first rod-containing cavity and the first connecting tube; the elastic member is fixedly arranged inside the box, and the elastic member is a cavity structure; the two ends of the second connecting tube are respectively connected with the interior of the elastic member and the first connecting tube, and liquid is preset in the interior of the elastic member and the second connecting tube; an overflow valve is fixedly installed on the second connecting tube.

[0013] By adopting the above technical solution, when grinding the edge of the paper tube, the operator pushes one of the grinding discs to slide away from the other grinding disc, thereby causing the compression telescopic rod to contract, and the liquid in the second rodless cavity flows into the first rod cavity, causing the two movable ends of the double-headed telescopic rod to contract, avoiding interference with the movable ends of the double-headed telescopic rod when the paper tube is put on the fixed rod, thereby facilitating the grinding of the paper tube.

[0014] After the paper tube is put on the fixed rod, the operator loosens the grinding disc, and under the action of the compression spring, the telescopic rod is compressed and extended, so that the liquid in the first rod-containing cavity is squeezed and flows into the second rodless cavity, thereby 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 fixed rod.

[0015] When the driving assembly drives the fixed rod to rotate, 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.

[0016] During the edging process, as the edging progresses, the length of the paper tube gradually shortens. Under the action of the compression spring, the compression telescopic rod extends, but at this time the liquid in the second rodless cavity is full, so the liquid in the first rod cavity enters the elastic part, so that the compression telescopic rod can still extend to compress the grinding disc.

[0017] Optionally, one end of the first connecting tube close to the second rodless cavity is coaxially arranged inside the fixed rod and is rotatably connected to the fixed rod; the first connecting tube is rotatably connected to the fixed end of the double-headed telescopic rod.

[0018] By adopting the above technical solution, during the edging process, the first connecting pipe does not rotate with the rotation of the fixed rod, but is in a fixed state, thereby preventing the first connecting pipe from being entangled on the fixed rod and preventing the first connecting pipe from being worn when the fixed rod rotates.

[0019] Optionally, the driving assembly includes a motor and a rotating shaft; the motor is fixedly arranged inside the box, and the output shaft of the motor is coaxially arranged with the fixed rod; both ends of the rotating shaft are coaxially fixedly connected with the output shaft of the motor and the fixed rod respectively.

[0020] By adopting the above technical solution, when grinding the edge of the paper tube, the operator starts the motor, and the motor drives the rotating shaft to rotate, thereby driving the fixed rod and the paper tube to rotate.

[0021] Optionally, a dust collector head is provided inside the box body, the dust collector head is connected to a dust collection device, and the dust collector head is used to absorb paper scraps and dust inside the box body.

[0022] By adopting the above technical solution, during the edging process, the dust collector head is always in working condition to collect paper scraps in the box to prevent them from adhering to the paper tube during the subsequent removal of the paper tube, thereby facilitating the subsequent winding of the paper.

[0023] 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.

[0024] By adopting the above technical solution, the fixed rod can rotate smoothly and the grinding disc can slide relative to the fixed rod smoothly, and the fixed rod can be prevented from being worn by the grinding disc.

[0025] Optionally, a protective door is provided at the opening of the box body; the protective door is hinged to the box body.

[0026] By adopting the above technical solution, when performing edging operations, the protective door is closed to prevent paper scraps from flying out and requiring additional cleaning by the operator, thereby facilitating use.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a drive component, compared with the traditional paper tube fixed grinding disc rotating grinding method, the paper tube is ground by the grinding disc fixed to the rotating method. When the paper tube rotates, the paper scraps generated by grinding fall on the surface of the paper tube and move away from the paper tube under the action of centrifugal force, thus avoiding the attachment of paper scraps to the paper tube and facilitating the subsequent paper winding; 2. By setting up a clamping assembly, during the edging process, as the edging progresses, the length of the paper tube gradually shortens. 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. The operator does not need to manually adjust the position of the paper tube, and the paper tube and the grinding disc can always be in contact, thus facilitating the edging of the paper tube; 3. After the paper tube is placed on the fixed rod by setting a fixing assembly, the operator releases the grinding disc. Under the action of the compression spring, the telescopic rod is compressed 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 fixed 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 placed on the fixed rod, thereby facilitating the edge grinding of the paper tube. 4. By setting the elastic part, during the edging process, as the edging progresses, the length of the paper tube gradually shortens. Under the action of the compression spring, the compression telescopic rod extends, but at this time the liquid in the second rodless cavity is in a full state, so the liquid in the first rod cavity enters the elastic part, so that the compression telescopic rod can still extend to compress the grinding disc.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The embodiment of the present application discloses a dust removal device for an edge grinding machine. Figure 1 The paper winder's edge grinding and dust removal device includes a housing 1, a fixing assembly 2, a drive assembly 3, and a pressing assembly 4. The housing 1 is horizontally arranged, with one side of the housing 1 being open. A protective door 7 is provided at the opening of the housing 1. The top of the protective door 7 is hinged to the housing 1, with the hinge axis being horizontal. The protective door 7 is made of a transparent material. A handle is fixed to the protective door 7.

[0032] Reference Figure 2 Two grinding discs 11 are fixedly mounted inside the housing 1, arranged parallel to each other. Sliders are fixedly mounted at the bottom of the grinding discs 11. Sliders are positioned within slots defined on the bottom wall of the housing 1 and are slidably connected to the housing 1. Sliding sleeves 6 are inserted into the grinding discs 11 and are fixedly connected to the grinding discs 11. A fixing rod 12 is coaxially inserted within the sleeves 6.

[0033] Reference Figure 2 , the clamping assembly 4 is provided with two groups, and the clamping assembly 4 corresponds to the grinding disc 11 one by one. The clamping assembly 4 includes a clamping telescopic rod 41 and a clamping spring 42. The clamping telescopic rod 41 is horizontally arranged in the box body 1, and the fixed end of the clamping telescopic rod 41 is fixedly connected to the bottom wall of the box body 1, and the movable end of the clamping telescopic rod 41 is fixedly connected to the side of the grinding disc 11 away from the other grinding disc 11. The movable end of the clamping telescopic rod 41 divides the interior of the fixed end of the clamping telescopic rod 41 into a first rod cavity 411 and a first rodless cavity 412, and the first rod cavity 411 is located between the first rodless cavity 412 and the grinding disc 11. The clamping spring 42 is horizontally arranged in the first rodless cavity 412, and its two ends are fixedly connected to the movable end of the clamping telescopic rod 41 and the fixed end of the clamping telescopic rod 41 respectively, and the clamping spring 42 is always in a compressed state.

[0034] When edging the paper tube, the operator pulls the handle to rotate the protective door 7 upward and open it, and then pushes one of the grinding discs 11 to slide away from the other grinding disc 11, so that the compression telescopic rod 41 continues to compress the compression spring 42 to shrink, and then the operator puts the paper tube on the fixed rod 12 and releases the grinding disc 11. Under the action of the compression spring 42, the compression telescopic rod 41 extends, thereby pushing the grinding disc 11 to abut against the paper tube. During the edging process, as the edging progresses, the length of the paper tube gradually shortens. Since the compression spring 42 is always in a compressed state, the grinding disc 11 is always pushed to abut against the paper tube.

[0035] Reference Figure 2 and Figure 3 The fixed assembly 2 includes a double-headed telescopic rod 21, a fixed spring 22, and a first connecting pipe 23. The fixed end of the double-headed telescopic rod 21 is vertically arranged inside the fixed rod 12 and fixedly connected to the fixed rod 12. The two movable ends of the double-headed telescopic rod 21 are both slidably connected to the fixed rod 12, and the sliding axis is 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 cavities 211 and a second rodless cavity 212. The second rodless cavity 212 is located between the two second rod cavities 211. Two fixed springs 22 are provided, and correspond one-to-one to the second rod cavities 211. The fixed spring 22 is provided in the second rod cavity 211, and its two ends are fixedly connected to the movable end of the double-headed telescopic rod 21 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 fixed spring 22.

[0036] Reference Figure 2 and Figure 3 One end of the first connecting tube 23 is vertically inserted into the fixed end of the compression telescopic rod 41 and communicates with the interior of the first rod-mounted cavity 411. The other end of the first connecting tube 23 is horizontally inserted into the interior of the fixed rod 12 and is coaxially rotatably connected to the fixed rod 12. The end of the first connecting tube 23 located within the fixed rod 12 communicates with the interior of the second rodless cavity 212. The first connecting tube 23 is rotatably connected to the fixed end of the double-ended telescopic rod 21. Liquid is preset in the second rodless cavity 212, the first rod-mounted cavity 411, and the first connecting tube 23.

[0037] Reference Figure 2 The elastic member 24 is fixedly mounted on the inner sidewall of the housing 1 and has a hollow structure. The ends of the second connecting tube 25 are connected to the interior of the elastic member 24 and the first connecting tube 23, respectively. Both the interior of the elastic member 24 and the second connecting tube 25 are filled with liquid. A relief valve 251 is fixedly mounted on the second connecting tube 25. The actuation pressure of the relief valve 251 is greater than the elastic force of the fixed spring 22.

[0038] In the initial state, due to the presence of liquid in the second rodless cavity 212, the two movable ends of the double-headed telescopic rod 21 are in an extended state. When the operator pushes the grinding disc 11 to slide away from the other grinding disc 11, thereby shrinking the compression telescopic rod 41, the volume in the first rod cavity 411 increases, and under the action of the fixed spring 22, the liquid in the second rodless cavity 212 flows into the first rod cavity 411 through the first connecting tube 23, causing the two movable ends of the double-headed telescopic rod 21 to shrink. After the operator puts the paper tube on the fixed rod 12, he releases 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 through the first connecting tube 23 and flow into the second rodless cavity 212, 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, thereby fixing the paper tube to the fixed rod 12.

[0039] During the edging process, as the edging progresses, the length of the paper tube gradually decreases. 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 contact the paper tube. At this time, the liquid in the second rodless chamber 212 is full. Therefore, when the volume of the first rod chamber 411 decreases, the liquid in the first rod chamber 411 enters the elastic member 24 through the first connecting pipe 23 and the second connecting pipe 25, causing the elastic member 24 to expand.

[0040] When the edging is completed, the operator pushes the grinding disc 11 to slide away from the other grinding disc 11, thereby contracting the compression telescopic rod 41 and increasing the volume of the first rod chamber 411. Under the elastic force of the fixed spring 22 and the elastic member 24, the liquid in the elastic member 24 and the liquid in the second rodless chamber 212 flow back to the first rod chamber 411 through the first connecting tube 23 and the second connecting tube 25. The operator removes the paper tube and can proceed with the edging operation of the next paper tube.

[0041] Reference Figure 2 The drive assembly 3 includes a rotating shaft 32 and a motor 31. The rotating shaft 32 is coaxially fixedly connected to the fixing rod 12. The motor 31 is arranged inside the box body 1 and is fixedly connected to the side wall of the box body 1. The output shaft of the motor 31 is coaxially fixedly connected to the rotating shaft 32.

[0042] After the paper tube is fixed to the fixed rod 12, the operator pulls the handle to rotate the protective door 7 downward and close it, and then starts the motor 31. The motor 31 drives the rotating shaft 32 to rotate, thereby driving the fixed 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 edge of the paper tube.

[0043] 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.

[0044] 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.

[0045] Reference Figure 2 A dust collecting head 5 is fixedly provided on the top of the box body 1 , and the dust collecting head 5 is connected to the dust collecting device. The dust collecting head 5 is used to absorb paper scraps and dust in the box body 1 .

[0046] During the edging process, the dust collecting head 5 is in working condition, sucking the flying paper scraps and dust in the box body 1 to prevent them from adhering to the paper tube during the subsequent removal of the paper tube.

[0047] The implementation principle of the edge grinding and dust removal device of a paper reeling machine in the embodiment of the present application is as follows: When edging a paper tube, the operator pulls the handle to swing the protective door 7 upward and open it, pushing one grinding disc 11 to slide away from the other grinding disc 11, causing the compression spring 42 to shrink and the volume of the first rod cavity 411 to increase. 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-ended telescopic rod 21 to shrink.

[0048] The operator then places the paper tube on the fixed rod 12, loosens the grinding disc 11, and, under the action of the compression spring 42, compresses and extends the telescopic rod 41, squeezing the liquid in the first rod chamber 411 through the first connecting pipe 23 and flowing into the second rodless chamber 212. This pushes the two movable ends of the double-ended telescopic rod 21 to extend until they abut against the inner wall of the paper tube, thereby securing the paper tube to the fixed rod 12. The extension of the telescopic rod 41 pushes the grinding disc 11 into abutment with the paper tube.

[0049] After the paper tube is fixed to the fixed rod 12, the operator pulls the handle to rotate the protective door 7 downward and close it, and then starts the motor 31. The motor 31 drives the rotating shaft 32 to rotate, thereby driving the fixed 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 edge of the paper tube.

[0050] During the edging process, as the edging progresses, the length of the paper tube gradually decreases. Since the compression spring 42 is always in a compressed state, it pushes the compression telescopic rod 41 to continue to extend, and the grinding disc 11 always contacts the paper tube. At this time, the liquid in the second rodless chamber 212 is full. Therefore, when the volume of the first rod chamber 411 decreases, the liquid in the first rod chamber 411 enters the elastic member 24 through the first connecting pipe 23 and the second connecting pipe 25.

[0051] When the paper tube is rotating and edge grinding, under the action of centrifugal force, the paper scraps adsorbed on the surface of the paper tube due to electrostatic action move away from the paper tube, thereby preventing the paper scraps from adhering to the paper tube. At the same time, the dust collector 5 is in operation to absorb the flying paper scraps and dust in the box body 1.

[0052] When the edging is completed, the operator pulls the handle to rotate the protective door 7 upward and open it, and then pushes the grinding disc 11 to slide away from the other grinding disc 11, thereby causing the compression telescopic rod 41 to contract and the volume in the first rod chamber 411 to increase. Under the elastic force of the fixed spring 22 and the elastic member 24, the liquid in the elastic member 24 and the liquid in the second rodless chamber 212 flow back to the first rod chamber 411 through the first connecting tube 23 and the second connecting tube 25. The operator removes the paper tube and can proceed with the edging operation of the next paper tube.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
