Description

Technical Field

[0001] The present invention relates to the technical field of paper tape processing, and in particular to a paper folding machine. Background Art

[0002] As a core link in packaging, printing, and paper product production, the paper folding efficiency and accuracy of paper tape processing directly affect the product quality, production cost, and large-scale production capacity. Traditional paper folding processes have problems such as low efficiency and poor consistency, especially when dealing with large-scale production requirements, the problems are more significant. With the popularization of automation technology, some mechanical paper folding equipment has gradually become automated, but the existing technology still has the following key defects:

[0003] Among them, most existing equipment does not integrate a pre-indentation function, or the indentation mechanism and the edge folding mechanism are independent of each other; due to the lack of precise pre-indentation guidance, the paper tape is prone to problems such as crease deviation and edge wrinkling during the folding process, resulting in a reduction in the qualified rate of finished products and the need for repeated adjustment and correction, which seriously restricts the production efficiency.

[0004] Secondly, some equipment adopts a single-sided edge folding structure and needs to complete the folding of the left and right sides of the paper tape in two times; this not only increases the equipment complexity and operation steps, but also causes the conveying paths to intersect, easily leading to paper tape jamming or deformation, further affecting the processing accuracy and speed.

[0005] In addition, the edge folding components of existing equipment are mostly of fixed design and cannot flexibly adjust the folding position according to different paper tape widths; when facing diverse product requirements, it is necessary to frequently replace the mold or adjust the equipment structure, significantly increasing the production preparation time and cost. Therefore, a paper folding machine is provided to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a paper folding machine for the deficiencies of the existing technology to solve the technical problems of low paper folding accuracy of the existing paper folding machine and the inability to fold paper tapes of different sizes.

[0007] To achieve the above purpose, the technical solution of the present invention is as follows:

[0008] A paper folding machine includes a deviation correction mechanism and a paper folding mechanism. The paper folding mechanism includes a frame. The frame is equipped with a first indentation mechanism for continuously conveying the unfolded paper tape, and is also equipped with a right edge folding component and a left edge folding component arranged in sequence along the paper tape conveying direction. The left edge folding component and the right edge folding component are movably arranged on the frame, and the moving direction is the same as the width direction of the paper tape;

[0009] The left edge folding component and the right edge folding component are respectively used for folding the left and right length edges of the unfolded paper tape, and the deviation correction mechanism is connected to the first indentation mechanism to correct the deviation of the paper tape during the conveying process;

[0010] The indentation mechanism includes a second supporting frame and a fourth threaded rod rotatably arranged on the second supporting frame. The axis of the fourth threaded rod is arranged horizontally and perpendicular to the conveying direction of the paper tape. The fourth threaded rod is provided with a plurality of indentation parts for indenting the surface of the paper tape. Support rollers for supporting the paper tape to be indented are provided below the indentation parts. The paper tape passes through between the indentation parts and the support rollers during the conveying process.

[0011] The beneficial effects of the present invention are as follows: before operating the paper folding machine, the paper tape is laid out first, and the staff first passes the paper tape through the correction mechanism and the first creasing mechanism in sequence, and then folds the right length edge of the end segment of the paper tape, and allows the folded segment to pass through the right folding edge component. Under the action of the right folding edge component, the right length edge of the paper tape continuously transitions from an unfolded state to a folded state during continuous conveying; then the staff folds the left length edge of the end segment of the paper tape, and after folding, allows it to pass through the left folding edge component. Under the action of the left folding edge component, the left length edge of the paper tape continuously transitions from an unfolded state to a folded state during continuous conveying.

[0012] When the paper folding machine is in operation, the deviation-correcting mechanism and the first creasing mechanism are started at the same time, the first creasing mechanism drives the paper tape in the unfolded state to be continuously conveyed, and during the conveying process, the deviation-correcting mechanism monitors the position of the paper tape in real time, and when the conveying track of the paper tape deviates, the deviation-correcting mechanism straightens the paper tape so that the paper tape is always conveyed in one direction, and after being conveyed to the right folding edge component, the right length side of the paper tape that reaches the right folding edge component is in a folded state, while the paper tape at the first creasing mechanism is in an unfolded state, so in the process of continuously conveying the paper tape In the process, it can gradually transition from the unfolded state to the folded state on the right length side, and the folding process is natural and smooth; the right length side of the paper tape is conveyed to the left folding assembly after being folded. Since the left length side of the paper tape arriving at the left folding assembly is in a folded state, and the right length side of the paper tape on the right folding assembly is in a folded state, in the process of continuous conveying of the paper tape, the paper tape with the folded right length side can be gradually transitioned to the paper tape with both the left and right length sides in a folded state, thereby realizing automatic and continuous paper folding processing and improving the folding efficiency.

[0013] In addition, during the continuous conveyance of the paper tape in the unfolded state by the first indentation mechanism, the indentation part is operated to contact the surface of the paper tape to be indented, and is supported by the support rollers at the same time, so as to press out dotted or linear traces on the surface of the paper tape, which is convenient for avoiding the situation of the paper tape being folded crookedly during the paper folding process, and improving the folding efficiency and accuracy. A number of indentation parts are provided, and the same number of indentation parts as the number of traces to be indented are operated, and multiple traces can be pressed out at the same time; by driving the fourth threaded rod to rotate, the position of the indentation part can be adjusted, so as to adjust the position of the indentation to adapt to paper tapes of different sizes. Moreover, the folding positions of the left and right length sides of the paper tape can also be adjusted by controlling the positions of the left folding edge assembly and the right folding edge assembly, so as to fold the paper tape into different states; according to paper tapes of different widths, the folding position and the indentation position are adjusted to realize the folding process of paper tapes of different widths.

Detailed implementation mode

[0032] The following will describe in detail an origami machine of the present invention with reference to the accompanying drawings.

[0033] As Figure 1-2 shown, an embodiment of an origami machine of the present invention includes a deviation rectifying mechanism 2 and an origami mechanism 3. The origami mechanism 3 includes a frame 301. The frame 301 is provided with a first indentation mechanism 4 for continuously conveying the unfolded paper tape 200 and performing indentation treatment on its surface. It is also provided with a right folding edge assembly 303 and a left folding edge assembly 305 arranged in sequence along the conveying direction of the paper tape 200. The left folding edge assembly 305 and the right folding edge assembly 303 are respectively used for folding the left and right length edges of the unfolded paper tape 200; the frame 301 is provided with a roller conveying assembly 306 placed at the end of the conveying track of the paper tape 200 and used for continuously conveying the folded paper tape 200. The deviation rectifying mechanism 2 is connected to the first indentation mechanism 4 to perform deviation rectifying treatment on the paper tape 200 during the conveying process.

[0034] The roller conveying assembly 306 is connected to the next mechanism. Before operating this origami machine, first lay the paper tape 200. The staff first passes the paper tape 200 through the deviation rectifying mechanism 2 and the first indentation mechanism 4 in sequence, then folds the right length edge of the end section of the paper tape 200, and makes the folded section pass through the right folding edge assembly 303. Under the action of the right folding edge assembly 303, during the continuous conveying of the paper tape 200, its right length edge continuously transitions from the unfolded state to the folded state; subsequently, the staff folds the left length edge of the end section of the paper tape 200, and after folding, makes it pass through the left folding edge assembly 305. Under the action of the left folding edge assembly 305, during the continuous conveying of the paper tape 200, its left length edge continuously transitions from the unfolded state to the folded state (as Figure 10 shown), after the paper tape 200 is folded left and right twice, it passes through the roller conveying assembly 306, and the roller conveying assembly 306 clamps and conveys the folded paper tape 200.

[0035] When this paper folding machine is in operation, the deviation rectifying mechanism 2, the first indentation mechanism 4 and the roller conveying assembly 306 are started simultaneously. The first indentation mechanism 4 drives the continuously conveyed paper tape 200 in the unfolded state. During the conveying process, the deviation rectifying mechanism 2 monitors the position of the paper tape 200 in real time. When the conveying trajectory of the paper tape 200 deviates, the deviation rectifying mechanism 2 straightens the paper tape 200 so that the paper tape 200 is always conveyed in one direction. After being conveyed onto the right folding edge assembly 303, since the right length edge of the paper tape 200 reaching the right folding edge assembly 303 is in a folded state, while the paper tape 200 located at the first indentation mechanism 4 is in an unfolded state, during the continuous conveying of the paper tape 200, it can gradually transition from the unfolded state to the state where the right length edge is in a folded state, and the folding process is natural and smooth. Similarly, the right length edge of the paper tape 200 is conveyed onto the left folding edge assembly 305 after being folded. Since the left length edge of the paper tape 200 reaching the left folding edge assembly 305 is in a folded state, while the right length edge of the paper tape 200 located at the right folding edge assembly 303 is in a folded state, during the continuous conveying of the paper tape 200, the paper tape 200 with the right length edge in a folded state can be gradually transitioned to the paper tape 200 with both left and right length edges in a folded state (as Figure 10 shown), and finally the roller conveying assembly 306 clamps and conveys the folded paper tape 200 to be conveyed to the next mechanism for processing.

[0036] In addition, during the process of continuously conveying the paper tape 200 in the unfolded state by the first indentation mechanism 4, the surface of the paper tape 200 will be indentation treated to press out traces in the shape of a dotted line or a straight line, so as to improve the folding efficiency and avoid the situation of the paper tape 200 being folded crookedly in the subsequent paper folding process by the left folding edge assembly 305 and the right folding edge assembly 303.

[0037] In this embodiment, the left hemming assembly 305 and the right hemming assembly 303 can move horizontally on the frame 301 along the width direction of the paper tape 200. Specifically, at least two first threaded rods 302 and at least two second threaded rods 304 are rotatably mounted on the frame 301. The length directions of the first threaded rod 302 and the second threaded rod 304 are both parallel to the width direction of the paper tape 200 during the conveying process. The right hemming assembly 303 is threadedly connected to the first threaded rod 302, and the left hemming assembly 305 is threadedly connected to the second threaded rod 304. When driving the plurality of first threaded rods 302 to rotate synchronously, the right hemming assembly 303 can be controlled to move horizontally on the frame 301 along the width direction of the paper tape 200. Similarly, when driving the plurality of second threaded rods 304 to rotate synchronously, the left hemming assembly 305 can be controlled to move horizontally on the frame 301 along the width direction of the paper tape 200. By controlling the positions of the left hemming assembly 305 and the right hemming assembly 303, the folding positions of the left and right length edges of the paper tape 200 can be adjusted, so as to fold the paper tape 200 into different states (such as Figure 11 shown). Moreover, the positions of the two can be adjusted according to paper tapes 200 with different widths, so as to fold paper tapes 200 with different widths.

[0038] In addition, a second indentation mechanism 41 with the same function as the first indentation mechanism 4 is provided between the right hemming assembly 303 and the left hemming assembly 305, and the second indentation mechanism 41 and the first indentation mechanism 4 are controlled separately. When it is necessary to fold only the right length edge of the paper tape 200, the second threaded rod 304 is driven to rotate to control the left hemming assembly 305 to deviate from the conveying track of the paper tape 200, and the first indentation mechanism 4 only presses an indentation on the surface of the paper tape 200, so as to fold only the right length edge of the paper tape 200. Similarly, the first threaded rod 302 is driven to rotate to control the right hemming assembly 303 to deviate from the conveying track of the paper tape 200, and the second indentation mechanism 41 only presses an indentation on the surface of the paper tape 200, so as to fold only the left length edge of the paper tape 200.

[0039] Such as Figure 3-5As shown, the deviation correction mechanism 2 includes a base 201 and a bracket 202 arranged on the base 201. A pair of paper guide rollers 203 arranged in parallel and used to receive the paper tape 200 conveyed from the outside are provided on the top of the bracket 202. The axes of the paper guide rollers 203 are arranged horizontally and fixed to the top of the bracket 202. The paper guide rollers 203 are connected to the paper outlet end of an external paper feeding mechanism (not shown in the drawings). By running the paper feeding mechanism, the paper tape 200 can be continuously fed out, and then received by the paper guide rollers 203 and wound around the pair of paper guide rollers 203 to guide the paper tape 200. Among them, a third conveying roller 205 whose axis is parallel to the axis of the paper guide roller 203 is rotatably provided on the top of the bracket 202, and the conveyed paper tape 200 is sequentially wound around the paper guide roller 203 and the third conveying roller 205; by driving the third conveying roller 205 to rotate, the paper tape 200 is conveyed under the action of the friction between the surface of the third conveying roller 205 and the surface of the paper tape 200, and is conveyed to the subsequent correction position to correct the paper tape 200.

[0040] In this embodiment, each paper guide roller 203 is provided with a pair of limiting members 204 for limiting the paper tape 200 during the conveying process, and the distance between the limiting members 204 is adjustable. The distance between the two limiting members 204 is adjusted according to the width of the paper tape 200, and the paper tape 200 wound on the paper guide roller 203 is limited by the limiting members 204, and in cooperation with the third conveying roller 205, the paper tape 200 is always conveyed in one direction.

[0041] In order to drive the third conveying roller 205 to rotate, a driving motor 207 is installed on the top of the bracket 202, and the output shaft of the driving motor 207 is connected to one end of the third conveying roller 205 through a transmission component 208; the transmission component 208 is an existing structure, which can be a gear and a toothed belt structure. The driving motor 207 is operated, and the third conveying roller 205 is driven to rotate under the transmission action of the transmission component 208. A brush 206 for cleaning the surface of the paper tape 200 is installed beside the paper guide roller 203. When the paper tape 200 is wound on the paper guide roller 203, its surface will contact the bristles of the brush 206. In the process of driving the third conveying roller 205 to rotate to continuously convey the paper tape 200, the brush 206 automatically cleans the surface of the paper tape 200 to brush away the paper scraps or dust attached to its surface, so as to facilitate the subsequent processing of the paper tape 200.

[0042] Further, the deviation rectifying mechanism 2 further includes a swing frame 209. The initial end of the swing frame 209 is close to the support 202. The base 201 is provided with a fixed shaft 2010 arranged axially vertically, and the middle position of the initial end of the swing frame 209 is rotationally connected to the fixed shaft 2010. By providing the fixed shaft 2010, the swing frame 209 can swing back and forth on the base 201 around the axis of the fixed shaft 2010. The initial end and the terminal end of the swing frame 209 are respectively provided with a second deviation rectifying roller 2012 and a first deviation rectifying roller 2011 at the same height, and the axes of the first deviation rectifying roller 2011 and the second deviation rectifying roller 2012 are both parallel to the axis of the third conveying roller 205; the heights of the first deviation rectifying roller 2011 and the second deviation rectifying roller 2012 are lower than the height of the third conveying roller 205. During the conveying process, the paper tape 200 passes under the first deviation rectifying roller 2011 and the second deviation rectifying roller 2012 and is in close contact with the surfaces of both. During the process of driving the third conveying roller 205 to rotate to continuously convey the paper tape 200, the paper tape 200 is first conveyed downward, then passes under the first deviation rectifying roller 2011 and the second deviation rectifying roller 2012, from the initial end to the terminal end of the swing frame 209, and finally conveyed upward to be conveyed to the first indentation mechanism 4. During the conveying process, the paper tape 200 is always in a taut state; during the process of the paper tape 200 being conveyed along the above trajectory, the position of the continuously conveyed paper tape 200 is sensed by a sensor (not shown in the figure). When it is sensed that the paper tape 200 is deviated, the swing frame 209 is controlled to swing around the axis of the fixed shaft 2010. Under the frictional force when the surface of the paper tape 200 is in close contact with the surfaces of the two deviation rectifying rollers (i.e., the first deviation rectifying roller 2011 and the second deviation rectifying roller 2012), the conveying direction of the paper tape 200 can be adjusted to straighten it, so as to achieve deviation rectifying processing and prevent errors from occurring during the subsequent paper folding process of the paper tape 200.

[0043] In this embodiment, in order to control the swing of the swing frame 209, the deviation rectifying mechanism 2 further includes an adjustment cylinder 2015 arranged horizontally. The base 201 is provided with a first fixing member 2016, and the end of the swing frame 209 is provided with a second fixing member 2017. The end of the adjustment cylinder 2015 is hinged to the first fixing member 2016 through a hinge shaft, and the end of the telescopic rod of the adjustment cylinder 2015 is hinged to the second fixing member 2017 through a hinge shaft. The hinge shafts on the first fixing member 2016 and the second fixing member 2017 are both arranged vertically. After the sensor senses that the paper tape 200 is offset during the conveying process, the adjustment cylinder 2015 is operated to control the telescopic movement of its telescopic rod, so as to drive the swing frame 209 to swing back and forth around the axis of the fixed shaft 2010, and correct the deviation of the paper tape 200. A first protective housing 2018 for protecting the paper tape 200 is installed below the first deviation rectifying roller 2011 and the second deviation rectifying roller 2012. The first protective housing 2018 is fixedly arranged at the bottom of the base 201. Since the height positions of the first deviation rectifying roller 2011 and the second deviation rectifying roller 2012 are set relatively low, under the action of the first protective housing 2018, the paper tape 200 is isolated from the ground, preventing the paper tape 200 from contacting the ground when it is not in a taut state (before the paper tape 200 is continuously conveyed, the staff needs to manually pass the paper tape 200 under the first deviation rectifying roller 2011 and the second deviation rectifying roller 2012 for loading), so that the paper tape 200 will not be attached with dust.

[0044] Further, during the process of the adjustment cylinder 2015 controlling the swing of the swing frame 209, in order to improve the stability of the swing frame 209 during swinging, a second guiding portion 2014 and a first guiding portion 2013 are respectively installed at the initial end and the end of the swing frame 209. There are at least two second guiding portions 2014 and first guiding portions 2013, and they are symmetrically arranged based on the fixed shaft 2010, that is, the second guiding portion 2014 is symmetrically arranged based on the fixed shaft 2010, and the first guiding portion 2013 is symmetrically arranged based on the fixed shaft 2010. By respectively installing the second guiding portion 2014 and the first guiding portion 2013 at the initial end and the end of the swing frame 209, the swing frame 209 can be more stable during swinging.

[0045] The first guiding part 2013 includes a first guide rail 20131 installed on the base 201. The swinging frame 209 is provided with a first fixing block 20132, and a first roller 20133 is rotatably provided on the first fixing block 20132. The first roller 20133 can roll within the first guide rail 20131. Secondly, the second guiding part 2014 includes a second guide rail 20141 installed on the swinging frame 209. The base 201 is provided with a second fixing block 20142, and a second roller 20143 is rotatably provided on the second fixing block 20142. The second roller 20143 can roll within the second guide rail 20141. When the swinging frame 209 swings, it drives the first roller 20133 and the second guide rail 20141 to move around the axis of the fixed shaft 2010. At this time, the first roller 20133 rolls within the first guide rail 20131, and the second roller 20143 rolls within the second guide rail 20141, realizing the guiding of the swinging frame 209 and improving the stability during swinging. In addition, both the first guide rail 20131 and the second guide rail 20141 can be set as arc-shaped guide rails with a curvature, and the center point of the curvature coincides with the axis of the fixed shaft 2010. By setting them as arc-shaped guide rails with a curvature, the guiding effect on the swinging frame 209 is improved.

[0046] As Figure 6-8 shown, the right folding edge assembly 303 includes a support frame 3031 threadedly connected to the first threaded rod 302. The support frame 3031 is equipped with a first support plate 3032 and a second support plate 3033 that are arranged in sequence along the conveying direction of the paper tape 200 and are used to support the paper tape 200 during the folding process. The first support plate 3032 is arranged obliquely from bottom to top, and the second support plate 3033 is arranged obliquely from top to bottom. The end of the first support plate 3032 at the higher position is connected to the starting end of the second support plate 3033 at the higher position. A turning roller 3034 for turning the paper tape 200 during the folding process is rotatably provided between the two ends of the connection. The turning roller 3034 is arranged horizontally and perpendicular to the conveying direction of the paper tape 200. A folding edge guiding inclined block 3035 for guiding the right length edge of the paper tape 200 to be bent is arranged beside the right end of the turning roller 3034. During the continuous conveying of the paper tape 200, the paper tape 200 first passes through the first support plate 3032 to be conveyed from bottom to top. Under the turning action of the turning roller 3034, the paper tape 200 then passes through the second support plate 3033 to be conveyed from top to bottom. During the process of turning from the first support plate 3032 to the second support plate 3033, under the guiding action of the folding edge guiding inclined block 3035, the right length edge of the guiding paper tape 200 is bent and folded, gradually transitioning from the unfolded state to the state where the right length edge is in a folded state, thus realizing the continuous folding process.

[0047] In addition, a limiting plate 3036 for limiting the paper tape 200 with its right long side in a folded state is provided on the right side edge of the second supporting plate 3033. After the right long side of the paper tape 200 is folded, it is limited by the limiting plate 3036 during the conveying process to prevent deviation. A number of support rods 3037 arranged in an array along the conveying direction of the paper tape 200 are provided on the limiting plate 3036, and each support rod 3037 is provided with a paper pressing and limiting piece 3038 for flattening the folded edge of the paper tape 200. During the process of the folded paper tape 200 being conveyed, the folded edge passes between the paper pressing and limiting piece 3038 and the surface of the second supporting plate 3033. Under the action of the pressure applied by the paper pressing and limiting piece 3038, the folded edge of the paper tape 200 is flattened, improving the folding effect; the paper pressing and limiting piece 3038 also has the function of limiting and guiding the paper tape 200, improving the conveying efficiency.

[0048] The right folding edge assembly 303 and the left folding edge assembly 305 are symmetrically arranged one in front of the other based on the conveying trajectory of the paper tape 200. The folding edge guiding inclined block 3035 on the right folding edge assembly 303 is arranged beside the right end of the turning roller 3034, while the folding edge guiding inclined block 3035 on the left folding edge assembly 305 is arranged beside the left end of the turning roller 3034. Therefore, the left long side of the guiding paper tape 200 is bent and then folded, gradually transitioning from the state where the right long side is folded to the state where both the left and right long sides are folded.

[0049] As Figure 9 shown, the roller conveying assembly 306 includes a first support frame body 3061 installed on the frame 301. A first conveying roller 3062 with a horizontally arranged axis and perpendicular to the conveying direction of the paper tape 200 is rotatably provided on the first support frame body 3061. A first fixing frame 3063 is also provided, and a first pressing roller 3064 for pressing the paper tape 200 against the first conveying roller 3062 is rotatably provided on the first fixing frame 3063. The first fixing frame 3063 can rotate on the first support frame body 3061, thereby driving the first pressing roller 3064 to approach or move away from the first conveying roller 3062. The first conveying roller 3062 receives the folded paper tape 200. After the paper tape 200 passes between the first conveying roller 3062 and the first pressing roller 3064, the first fixing frame 3063 is controlled to rotate to drive the first pressing roller 3064 to approach the first conveying roller 3062, pressing the paper tape 200 against the first conveying roller 3062 through the first pressing roller 3064. Subsequently, the first conveying roller 3062 is driven to rotate. Under the action of the frictional force generated between the surface of the first conveying roller 3062 and the surface of the paper tape 200, a pulling force is generated on the paper tape 200, thereby realizing the continuous conveying of the paper tape 200.

[0050] In addition, the first support frame 3061 is also rotatably provided with a second conveying roller 3066 and a third threaded rod 3067 whose axes are parallel to the axis of the first conveying roller 3062. A number of control components 3068 are arranged on the third threaded rod 3067, and each control component 3068 is provided with a second pressing roller 3069 for flattening the folded paper tape 200. The control component 3068 is used to control the second pressing roller 3069 to approach or move away from the second conveying roller 3066. After the folded paper tape 200 is conveyed by the first conveying roller 3062, it passes through between the second conveying roller 3066 and the second pressing roller 3069. Subsequently, the control component 3068 is operated to control the second pressing roller 3069 to approach the second conveying roller 3066, and the paper tape 200 is pressed tightly on the second conveying roller 3066, thereby realizing the flattening process of the paper tape 200. The first pressing roller 3064 and the second pressing roller 3069 are set to be movable to facilitate the staff to pre-lay the paper tape 200. Secondly, according to the different sizes of the folded paper tape 200, the third threaded rod 3067 can be driven to rotate to control the positions of the control components 3068, so as to adjust the flattening position, and make the second pressing roller 3069 at the outermost side align with the edge of the folded paper tape 200.

[0051] The first support frame 3061 is provided with a first guiding roller 3065 disposed between the first conveying roller 3062 and the second conveying roller 3066, and is also provided with a second guiding roller 30610 for guiding the folded paper tape 200 to the next mechanism. The folded paper tape 200 is wound around the first conveying roller 3062, the first guiding roller 3065, the second conveying roller 3066 and the second guiding roller 30610 in sequence along the conveying direction, and is guided during the conveying process, so that the paper tape 200 is conveyed along the specified direction.

[0052] As Figure 12-13 shown, the first indentation mechanism 4 includes a second support frame 401 and a fourth conveying roller 403 rotatably arranged on the second support frame 401. The fourth conveying roller 403 is used for continuously conveying the paper tape 200; the second support frame 401 is also provided with a second fixing frame 404 and a number of third guiding rollers 402. The third guiding rollers 402 are used to receive the paper tape 200 sent by the deviation rectifying mechanism 2 and guide the paper tape 200 to be wound around the fourth conveying roller 403. The second fixing frame 404 is rotatably provided with a pressing roller 405 for pressing the paper tape 200 tightly on the fourth conveying roller 403. The paper tape 200 sent by the previous mechanism is received and guided by the third guiding rollers 402, so as to be guided to be wound around the fourth conveying roller 403, and passes through between the fourth conveying roller 403 and the pressing roller 405. The paper tape 200 is pressed tightly on the fourth conveying roller 403 by the pressing roller 405. Subsequently, the fourth conveying roller 403 is driven to rotate, and under the action of the frictional force generated between the surface of the fourth conveying roller 403 and the surface of the paper tape 200, a pulling force is generated on the paper tape 200, thereby realizing the conveying of the paper tape 200.

[0053] During the conveying process, in order to indent the surface of the paper tape 200, the second support frame 401 is rotatably provided with a fourth threaded rod 407 whose axis is parallel to the axis of the fourth conveying roller 403. A number of indentation portions 408 for indenting the surface of the paper tape 200 are mounted on the fourth threaded rod 407. Below the indentation portion 408, there is a support roller 406 for supporting the paper tape 200 to be indented. The paper tape 200 during the conveying process passes through between the indentation portion 408 and the support roller 406. When indentation is required, the indentation portion 408 is operated to contact the surface of the paper tape 200 to be indented, and at the same time, it is supported by the support roller 406. During the process of conveying the paper tape 200, a dotted or linear trace is pressed out on the surface of the paper tape 200, which is convenient for the subsequent paper folding process of the paper tape 200; in addition, a number of indentation portions 408 are provided. If several traces need to be pressed, the same number of indentation portions 408 are operated, and multiple traces can be pressed out simultaneously. By driving the fourth threaded rod 407 to rotate, the position of the indentation portion 408 can be adjusted, thereby adjusting the position of the indentation to adapt to paper tapes 200 of different sizes.

[0054] In this embodiment, the second support frame 401 is further provided with a fourth guide roller 4010, and the fourth guide roller 4010 is used to guide the paper tape 200 that has been indented to the next mechanism for paper folding processing; the paper tape 200 passes through the third guide roller 402, between the indentation portion 408 and the support roller 406, between the fourth conveying roller 403 and the pressing roller 405, and the fourth guide roller 4010 in sequence. A second protective housing 4011 for protecting the paper tape 200 during the conveying process is mounted beside the fourth guide roller 4010, preventing the paper tape 200 from falling and contacting the ground and sticking to stains during the process of replacing the new paper tape 200 (the paper tape 200 is in a relaxed state during the laying process). The second support frame 401 is provided with a control panel 4012 for controlling the operation of the indentation portion 408 and the rotation of the fourth threaded rod 407; by operating the control panel 4012, the fourth threaded rod 407 can be rotated a specified number of turns, thereby adjusting the indentation portion 408 to a specified position; and moreover, the operation of the indentation portion 408 can be controlled to contact the surface of the paper tape 200 for continuous indentation processing.

[0055] Such as Figure 14As shown in the figure, the indentation part 408 includes a support base 4081 and a threaded sleeve 4082 installed on the support base 4081. The threaded sleeve 4082 is threadedly connected to the fourth threaded rod 407. After controlling the rotation of the fourth threaded rod 407, with the cooperation of the threaded connection with the threaded sleeve 4082, the support base 4081 is controlled to move along the axis of the fourth threaded rod 407. Among them, a limit housing 4089 is fixedly arranged on the support base 4081, and the second support frame 401 is provided with a limit cross beam 409 for contacting the limit housing 4089. When the fourth threaded rod 407 rotates counterclockwise (the rotation direction is based on Figure 13 as a reference), the limit cross beam 409 is blocked by the limit housing 4089 to prevent the fourth threaded rod 407 from driving the support base 4081 and the threaded sleeve 4082 to rotate together when rotating. By blocking the limit housing 4089 with the limit cross beam 409, the support base 4081 can only move along the axis of the fourth threaded rod 407. In addition, the limit housing 4089 can also slide along the axis of the fourth threaded rod 407 on the limit cross beam 409, which can also play a role in limiting the support base 4081.

[0056] The bottom of the support base 4081 is rotatably provided with a movable arm 40810 through a pin. The axis of the pin on the support base 4081 is parallel to the axis of the fourth threaded rod 407. Under the action of the pin, the movable arm 40810 can move around the axis of the pin. One end of the movable arm 40810 is provided with a support shaft 40811 whose axis is parallel to the axis of the fourth conveying roller 403. The support shaft 40811 is rotatably provided with a convex gear 40812 for contacting the surface of the paper tape 200 during the conveying process to make an indentation. During the process of the fourth conveying roller 403 rotating to convey the paper tape 200, the movable arm 40810 moves to drive the convex gear 40812 to move towards the direction close to the paper tape 200, so that the convex teeth on the circumference of the convex gear 40812 contact the surface of the paper tape 200. Under the action of the frictional force between the convex gear 40812 and the surface of the paper tape 200, the convex gear 40812 rolls on the surface of the paper tape 200 to press out a dotted line-shaped trace, and the paper tape 200 is automatically indented.

[0057] In order to control the movement of the movable arm 40810 on the support base 4081, a pressing cylinder 40813 for pressing the movable arm 40810 to make the convex gear 40812 contact the surface of the paper tape 200 is installed on the support base 4081. An installation member 40814 is provided at one end of the movable arm 40810 away from the support shaft 40811. A second spring 40815 is provided between the installation member 40814 and the support base 4081 for applying a force to the movable arm 40810 to separate the convex gear 40812 from the surface of the paper tape 200. After the pressing cylinder 40813 operates, the telescopic rod of the pressing cylinder 40813 extends to press the movable arm 40810, making the convex gear 40812 contact the surface of the paper tape 200. At this time, the second spring 40815 is compressed; after the telescopic rod of the pressing cylinder 40813 contracts, under the action of the thrust applied by the second spring 40815 to the movable arm 40810, the movable arm 40810 is pushed to reset, separating the convex gear 40812 from the surface of the paper tape 200, thereby stopping the indentation process.

[0058] In this embodiment, the threaded sleeve 4082 is rotatably arranged on the support base 4081. A sliding chamber 4083 is formed inside the support base 4081. An electromagnet 4084 that can move in a direction close to or away from the threaded sleeve 4082 is arranged in the sliding chamber 4083. After being energized, the electromagnet 4084 moves in a direction close to the threaded sleeve 4082 to attract it, and after being powered off, the electromagnet 4084 moves in a direction away from the threaded sleeve 4082 to separate from it. When the electromagnet 4084 separates from the threaded sleeve 4082, the fourth threaded rod 407 is controlled to rotate, driving the threaded sleeve 4082 to rotate together, making the threaded sleeve 4082 idle on the support base 4081, so that the support base 4081 cannot be controlled to move along the axis of the fourth threaded rod 407 (that is, the position of the indentation part 408 cannot be adjusted); since there are multiple indentation parts 408 on the fourth threaded rod 407, when only the position of one indentation part 408 needs to be adjusted, the electromagnet 4084 in this indentation part 408 is energized (the electromagnets 4084 in other indentation parts 408 are not energized), making the electromagnet 4084 attract the threaded sleeve 4082. After the fourth threaded rod 407 rotates, the threaded sleeve 4082 on this indentation part 408 will not idle (the threaded sleeves 4082 on other indentation parts 408 will idle), and the position of this indentation part 408 can be controlled to move along the axis of the fourth threaded rod 407 to achieve position adjustment. In addition, the positions of multiple indentation parts 408 can also be adjusted simultaneously. When the position of which indentation part 408 needs to be adjusted, the electromagnet 4084 is energized.

[0059] After the electromagnet 4084 is powered off, in order to separate the electromagnet 4084 from the threaded sleeve 4082, a third fixing member 4085 is provided at the top of the support base 4081. A guide rod 4086 is slidably arranged on the third fixing member 4085, and the bottom end of the guide rod 4086 is fixedly arranged with the electromagnet 4084. Under the action of the guide rod 4086, the electromagnet 4084 can slide up and down on the third fixing member 4085 (that is, move in the direction close to or away from the threaded sleeve 4082). A limit block 4087 is arranged at the top end of the guide rod 4086, and a first spring 4088 for applying an upward thrust to the limit block 4087 to drive the electromagnet 4084 to reset is arranged between the limit block 4087 and the third fixing member 4085. When the electromagnet 4084 is powered on, the electromagnet 4084 moves in the direction close to the threaded sleeve 4082, so as to attract the threaded sleeve 4082. At this time, the first spring 4088 is compressed; when the electromagnet 4084 is powered off, under the action of the compressed first spring 4088, an upward thrust is applied to the limit block 4087, so as to drive the electromagnet 4084 to reset in the direction away from the threaded sleeve 4082, realizing the separation of the electromagnet 4084 from the threaded sleeve 4082.

[0060] In summary, it can be seen that the present invention has the excellent characteristics described above, so that it can enhance the efficiency never before achieved in the prior art and has practicality in use, becoming a product with extremely high practical value.

[0061] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
