Description

Technical Field

[0001] This invention relates to the field of cigarette packaging technology, and more particularly to a cardboard cutting, pre-folding, and transfer device and a cardboard cutting, pre-folding, and transfer method. Background Technology

[0002] Cardboard sheets are an important component of cigarette packaging. They are placed inside the cigarette packs and provide effective support for the cigarettes, preventing them from breaking under pressure during transportation or storage. They also stabilize the overall shape of the cigarette packs, preventing deformation and collapse due to compression, thus ensuring the integrity of the cigarette pack's appearance and the stability of the cigarette quality. The key processes in cardboard sheet formation are cardboard tape cutting, cardboard tape edge pre-folding, cardboard tape slitting into cardboard sheets, and cardboard sheet transfer and pressing into the mold box.

[0003] Currently, existing technologies use multiple sets of independent drive components to drive the execution components of each process. This not only results in a complex device structure, large assembly space, and high manufacturing costs, but also easily leads to process connection delays, affecting processing efficiency and accuracy stability. Furthermore, manual intervention is required in the material feeding and transfer process, resulting in a high proportion of labor costs. In addition, manual operation is subject to random deviations and low efficiency, making it difficult to ensure the consistency of cardboard sheet product quality.

[0004] Therefore, there is an urgent need for a paper cutting, pre-folding, and transfer device and a paper cutting, pre-folding, and transfer method to solve the above problems. Summary of the Invention

[0005] The first objective of this invention is to provide a cardboard cutting, pre-folding, and transfer device that reduces the overall structural complexity and assembly space occupation, lowers manufacturing and maintenance costs, ensures smooth and compact connections between processes, avoids manual feeding, saves labor costs, and achieves integrated operation of cardboard cutting, pre-folding, slitting, transfer, and pressing.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A paper cutting, pre-folding and transfer device includes a frame, a cutting and pre-folding mechanism, a slitting and transfer mechanism and a paper receiving and pressing mechanism, which are sequentially arranged on the frame along the paper conveying direction.

[0008] The cutting and pre-folding mechanism includes a first driving component, a cutting component, and a pre-folding component. The first driving component can drive the cutting component to cut a slit on the cardboard tape, and transport the cut cardboard tape to the pre-folding component. It can also drive the pre-folding component to pre-fold the edge of the cardboard tape, and transport the pre-folded cardboard tape to the slitting and transfer mechanism.

[0009] The slitting and transferring mechanism includes a second driving component, a slitting component, and a transferring component. The second driving component can drive the slitting component to slit the cardboard tape into cardboard pieces, and drive the transferring component to pick up the cardboard pieces and transfer them to the paper receiving and pressing mechanism.

[0010] The paper feeding and pressing mechanism includes a third drive assembly, a paper feeding assembly, and a paper pressing assembly. The paper feeding assembly includes a paper feeding plate, and the paper pressing assembly includes a paper pressing plate. The paper pressing plate is disposed above the paper feeding plate, and the two are arranged parallel to each other and spaced apart. The third drive assembly can drive the paper feeding plate and the paper pressing plate to reciprocate in the up and down direction synchronously or at a preset time interval. After the card is transferred between the paper pressing plate and the paper feeding plate, when the paper pressing plate and the paper feeding plate move downward at the same time, the card can be pressed into the mold box of the next station.

[0011] As an optional solution for a cardboard cutting and pre-folding transfer device, the cutting and pre-folding mechanism further includes a support assembly comprising an upper support and a lower support; the first drive assembly includes a first motor and a transmission gear, the output end of the first motor being connected to the transmission gear, and the first motor being capable of driving the transmission gear to rotate; the cutting assembly includes:

[0012] A first shaft, a first gear, and an auxiliary bushing are provided. The first shaft extends in the front-rear direction and is rotatably disposed on the left side of the upper support. The first gear is fixed to the end of the first shaft, and the auxiliary bushing is sleeved on the first shaft.

[0013] The second shaft, the second gear, and the cutting wheel extend along the front-rear direction and are rotatably disposed on the left side of the lower support. The second gear is fixed to the end of the second shaft, and the cutting wheel is sleeved on the second shaft and is correspondingly disposed with the auxiliary bushing.

[0014] The transmission gear meshes with the second gear, and the second gear meshes with the first gear. The rotation of the transmission gear drives the second gear and the first gear to rotate in opposite directions, which in turn drives the second shaft and the first shaft to rotate in opposite directions, thereby driving the cooperating cutting wheel and the auxiliary bushing to rotate in opposite directions, cutting the paper tape clamped between the cutting wheel and the auxiliary bushing.

[0015] As an alternative to a pre-folding transfer device for paperboard cutting, the pre-folding assembly includes:

[0016] The third shaft, the third gear, and the upper folding wheel are provided. The third shaft extends along the front-rear direction and is rotatably disposed on the right side of the upper support. The third gear is fixed to the end of the third shaft, and the upper folding wheel is sleeved on the third shaft.

[0017] The fourth shaft, the fourth gear, and the lower folding wheel are provided. The fourth shaft extends along the front-rear direction and is rotatably disposed on the right side of the lower support. The fourth gear is fixed to the end of the fourth shaft. The lower folding wheel is sleeved on the fourth shaft and is disposed corresponding to the upper folding wheel. The lower folding wheel is provided with a paper folding angle.

[0018] The transmission gear meshes with the fourth gear, and the fourth gear meshes with the third gear. The rotation of the transmission gear drives the fourth gear and the third gear to rotate in opposite directions, driving the fourth shaft and the third shaft to rotate in opposite directions, which in turn drives the cooperating lower folding wheel and the upper folding wheel to rotate in opposite directions, so that the edge of the cardboard tape passing between the folding angle and the upper folding wheel is pre-folded.

[0019] As an optional solution for a cardboard cutting and pre-folding transfer device, the second drive assembly includes a second motor, a rotating shaft, and a flange cam. The output end of the second motor is connected to one end of the rotating shaft for transmission, and the flange cam is sleeved on the rotating shaft and fixedly connected to the rotating shaft. The slitting assembly includes:

[0020] The transmission link, the first roller, and the second roller extend along the vertical direction. The first roller and the second roller are spaced apart on the upper and lower sides of the flange cam edge and are rotatably mounted on one end of the transmission link.

[0021] The carrier pad and the movable cutter are provided. The other end of the transmission linkage away from the first roller and the second roller is connected to the carrier pad. The movable cutter is fixed on the carrier pad.

[0022] The L-shaped fixing seat is fixedly connected to the frame and has a slot for the paper tape to pass through. The other end of the rotating shaft is rotatably connected to the L-shaped fixing seat.

[0023] A paper pressing block is fixed above the L-shaped fixing base and above the bearing pad, and is used to press the card strip that passes through the slot and is located on the bearing pad.

[0024] A fixed cutter is installed on the paper pressing block and aligned vertically with the blade of the movable cutter.

[0025] The second motor can drive the rotating shaft to rotate, causing the flange cam to rotate eccentrically. The first roller and the second roller move synchronously with the edge of the flange cam, causing the transmission linkage to reciprocate in the up-down direction, so that the movable cutter reciprocates in the up-down direction relative to the fixed cutter, so that the cardboard tape passing through the fixed cutter and the movable cutter is cut into cardboard pieces.

[0026] As an optional solution for a pre-folding and transfer device for cutting paper, the slitting assembly also includes a connecting plate and a paper pressing component. The connecting plate is fixed to the paper pressing block, and the paper pressing component is fixed to the connecting plate and located above the support pad. It can press the paper strip on the support pad during the slitting operation so that the cut of the paper strip after slitting is flat.

[0027] As an optional solution for a paper cutting and pre-folding transfer device, the slitting assembly also includes a paper feed guide plate, which is installed at the slot of the L-shaped fixing seat. The paper feed guide plate is provided with a curved guide surface, which is used to guide the paper tape into the slot.

[0028] As an optional solution for a cardboard cutting and pre-folding transfer device, the second drive assembly further includes a first cam, which is disposed below and spaced apart from the flange cam. The first cam is sleeved on the rotating shaft and fixedly connected to it. The first cam has a first eccentric annular groove. The transfer assembly includes:

[0029] The first follower wheel, the rotating shaft, the first transmission rod, and the connecting block are provided. The first follower wheel is slidably disposed in the first eccentric annular groove. The rotating shaft extends in the vertical direction. One end of the first transmission rod is rotatably connected to the first follower wheel, and the other end is rotatably connected to one end of the rotating shaft. The other end of the rotating shaft is connected to the connecting block.

[0030] The mounting shaft and the suction element are connected to the connecting block. The suction element is sleeved on the mounting shaft and is configured to suction the cut cardboard pieces on the lower support pad.

[0031] The second motor can drive the rotating shaft to rotate, causing the first cam to rotate eccentrically. The first follower wheel moves along the first eccentric annular groove, driving the first transmission rod, the rotating shaft, the connecting block, and the mounting shaft to rotate, so as to transfer the adsorption element and the cardboard piece adsorbed on it to the paper receiving and pressing mechanism.

[0032] As an optional solution for a cardboard cutting and pre-folding transfer device, the third drive assembly includes a third motor, a support plate, a drive shaft, and a second cam. The support plate is fixed to the frame, the drive shaft extends in the left-right direction, one end of the drive shaft is connected to the output end of the third motor, and the other end is rotatably connected to the support plate. The second cam is sleeved on the drive shaft and fixedly connected to the drive shaft. The second cam is provided with a second eccentric ring groove.

[0033] The paper pressing assembly also includes a second follower wheel, a U-shaped connecting rod, and a first linkage rod. The second follower wheel is slidably disposed in the second eccentric annular groove. The U-shaped connecting rod is rotatably connected to the support plate. The first linkage rod extends along the vertical direction. One arm of the U-shaped connecting rod is rotatably connected to the second follower wheel, and the other arm is connected to one end of the first linkage rod. The other end of the first linkage rod is connected to the pressing paper.

[0034] The third motor can drive the transmission shaft to rotate, causing the second cam to rotate eccentrically. The second follower wheel moves along the second eccentric annular groove, causing the U-shaped connecting rod to rotate relative to the support plate, causing the first linkage rod to reciprocate in the up-down direction, and causing the pressure plate to reciprocate synchronously in the up-down direction, so as to press the cardboard sheet downward into the mold box of the next station.

[0035] As an optional solution for a cardboard cutting and pre-folding transfer device, the third drive assembly further includes a third cam, which is located to the left of the second cam and spaced apart from the second cam. The third cam is sleeved on the drive shaft and fixedly connected to the drive shaft. The third cam is provided with a third eccentric annular groove.

[0036] The paper splicing assembly also includes a third follower wheel, a second transmission rod, a connector, and a second linkage rod. The third follower wheel is rotatably connected to the second transmission rod and is slidably disposed in the third eccentric annular groove. One end of the second transmission rod is rotatably connected to the support plate, and the other end is rotatably connected to one end of the connector. The second linkage rod extends along the vertical direction, and one end of the second linkage rod is rotatably connected to the other end of the connector. The other end of the second linkage rod is connected to the paper splicing plate.

[0037] The third motor can drive the transmission shaft to rotate, causing the third cam to rotate eccentrically. The third follower wheel moves along the third eccentric annular groove, causing the second transmission rod to rotate relative to the support plate. This causes the connector, the second linkage rod, and the receiving plate to reciprocate in the up-down direction to catch the transferred cardboard.

[0038] The second objective of this invention is to provide a cardboard cutting, pre-folding, and transfer method, which is applied to the aforementioned cardboard cutting, pre-folding, and transfer device. This method shortens the time required for connecting each process, avoids manual feeding and transfer operations, saves labor costs, and ensures the processing accuracy and quality consistency of the cardboard sheets, thereby improving the processing efficiency of the cardboard sheets supporting the cigarette pack.

[0039] To achieve this objective, the present invention adopts the following technical solution:

[0040] A paperboard cutting, pre-folding, and transfer method, applied to the aforementioned paperboard cutting, pre-folding, and transfer device, includes the following steps:

[0041] Step S100: The cardboard tape is fed into the cutting and pre-folding mechanism. The first driving component drives the cutting component to cut the cutting slit on the cardboard tape and feeds the cut cardboard tape to the pre-folding component. The first driving component drives the pre-folding component to pre-fold the edge of the cardboard tape and feeds the pre-folded cardboard tape to the slitting and transfer mechanism.

[0042] Step S200: The pre-folded cardboard tape is conveyed to the slitting and transfer mechanism. The second drive component drives the slitting component to slit the cardboard tape into cardboard pieces, and drives the transfer component to pick up the cardboard pieces and transfer them to the paper receiving and pressing mechanism.

[0043] Step S300: The cardboard is conveyed to the paper receiving and pressing mechanism. In the initial state, the pressing plate is stationary, and the receiving plate rises to a preset position. The cardboard is transferred to the lower side of the pressing plate and the upper side of the receiving plate, that is, between the pressing plate and the receiving plate. After the receiving plate receives the cardboard, the pressing plate and the receiving plate move downwards at the same time to press the cardboard into the mold box of the next station. Subsequently, the pressing plate rises and the receiving plate remains stationary, waiting for the next cardboard to be transferred to the position.

[0044] Step S400: Repeat steps S100 to S300.

[0045] The beneficial effects of this invention are:

[0046] This invention provides a cardboard cutting, pre-folding, and transfer device. The cardboard tape is conveyed in a left-right direction and passes through a cutting and pre-folding mechanism on the frame. A first drive component drives a cutting component to cut a slit on the cardboard tape. The cardboard tape is then conveyed to a pre-folding component to complete edge pre-folding and then sent to a slitting and transfer mechanism. A second drive component drives a slitting component to cut the cardboard tape into cardboard pieces. A transfer component picks up the cardboard pieces and transfers them between the receiving plate and the pressing plate of the receiving and pressing mechanism. A third drive component drives the receiving plate and the pressing plate to move up and down synchronously or at a preset time interval. After the receiving plate receives the cardboard piece, the pressing plate and the receiving plate move downwards simultaneously, finally pressing the cardboard piece into the next station mold box. In this cardboard cutting, pre-folding, and transfer device, the linkage design of the first drive component simultaneously driving the cutting component and the pre-folding component, the second drive component simultaneously driving the slitting component and the transfer component, and the third drive component simultaneously driving the paper receiving component and the paper pressing component significantly simplifies the number of drive components, reduces the overall structural complexity and assembly space occupation, and lowers manufacturing and maintenance costs. At the same time, it makes the connection between cutting, pre-folding, slitting, transfer, paper receiving, and paper pressing processes more compact and smooth, avoiding the action delay of multi-drive step-by-step operations, realizing the integrated operation of cardboard cutting, pre-folding, slitting, transfer, and pressing, eliminating manual feeding, saving labor costs from the root, improving the overall efficiency and precision stability of cardboard sheet processing, and increasing the automation level of the entire cigarette packaging process.

[0047] This invention also provides a method for cutting, pre-folding, and transferring cardboard. By sequentially and continuously operating a cutting component, a pre-folding component, a slitting component, a transfer component, a paper-receiving component, and a paper-pressing component, the entire process of cutting, pre-folding, slitting, transferring, and pressing the cardboard tape is automated. This significantly shortens the time spent connecting each process, avoids manual feeding and transfer operations, saves labor costs at the source, and ensures the processing accuracy and quality consistency of the cardboard sheets, thereby improving the processing efficiency of the cardboard sheets supporting the cigarette pack.

The cardboard cutting, pre-folding, and transfer device includes a frame 1, a cutting and pre-folding mechanism 2, a slitting and transfer mechanism 3, and a paper receiving and pressing mechanism 4, which are sequentially arranged on the frame 1 along the conveying direction of the cardboard tape 101. The cutting and pre-folding mechanism 2 includes a first driving component, a cutting component 22, and a pre-folding component 23. The first driving component can drive the cutting component 22 to cut a cutting opening 1020 on the cardboard tape 101, and convey the cut cardboard tape 101 to the pre-folding component 23. It also drives the pre-folding component 23 to pre-fold the edge of the cardboard tape 101 and convey the pre-folded cardboard tape 101 to the slitting and transfer mechanism 3. The slitting and transfer mechanism 3 includes a second driving component 31, a slitting component 32, and a transfer component 33. Component 31 can drive the slitting component 32 to cut the cardboard tape 101 into cardboard pieces 102, and drive the transfer component 33 to absorb the cardboard pieces 102 and transfer them to the paper receiving and pressing mechanism 4.

After the cardboard piece 102 is transferred between the paper pressing plate 431 and the paper receiving plate 421, when the paper pressing plate 431 and the paper receiving plate 421 move downward at the same time, the cardboard piece 102 can be pressed into the mold box of the next station.

[0081] like Figures 1-2As shown, the cardboard tape 101 is conveyed in the left-right direction. After passing through the cutting and pre-folding mechanism 2 on the frame 1, the first drive component drives the cutting component 22 to cut a cutting slit 1020 on the cardboard tape 101. Then, the cardboard tape 101 is conveyed to the pre-folding component 23 to complete the edge pre-folding, and then sent to the slitting and transfer mechanism 3.

The third drive component 41 drives the receiving plate 421 and the pressing plate 431 to move up and down synchronously or at a preset time interval. After the receiving plate 421 receives the cardboard piece 102 in place, the pressing plate 431 and the receiving plate 421 move downward at the same time, and finally press the cardboard piece 102 into the next station mold box. In this cardboard cutting, pre-folding, and transfer device, the linkage design of the first drive component simultaneously driving the cutting component 22 and the pre-folding component 23, the second drive component 31 simultaneously driving the slitting component 32 and the transfer component 33, and the third drive component 41 simultaneously driving the paper receiving component 42 and the paper pressing component 43 significantly simplifies the number of drive components, reduces the overall structural complexity and assembly space occupation, and lowers manufacturing and maintenance costs. At the same time, it makes the connection between the cutting, pre-folding, slitting, transfer, paper receiving, and paper pressing processes more compact and smooth, avoids the action delay of multi-drive step-by-step operations, realizes the integrated operation of cardboard cutting, pre-folding, slitting, transfer, and pressing, avoids manual feeding, saves labor costs from the root, improves the overall efficiency and precision stability of cardboard sheet 102 processing, and improves the automation level of the entire cigarette packaging process.

[0082] The paper cutting and pre-folding transfer method in this embodiment is applied to the aforementioned paper cutting and pre-folding transfer device. The paper cutting and pre-folding transfer method includes the following steps:

[0083] Step S100: The cardboard tape 101 is fed into the cutting and pre-folding mechanism 2. The first driving component drives the cutting component 22 to cut a cutting opening 1020 on the cardboard tape 101, and the cut cardboard tape 101 is fed into the pre-folding component 23. The first driving component drives the pre-folding component 23 to pre-fold the edge of the cardboard tape 101, and the pre-folded cardboard tape 101 is fed into the slitting and transfer mechanism 3.

[0084] Step S200: The pre-folded cardboard tape 101 is conveyed to the slitting and transfer mechanism 3. The second drive component 31 drives the slitting component 32 to slit the cardboard tape 101 into cardboard pieces 102, and drives the transfer component 33 to absorb the cardboard pieces 102 and transfer them to the paper receiving and pressing mechanism 4.

[0085] Step S300: The cardboard piece 102 is conveyed to the paper receiving and pressing mechanism 4. In the initial state, the pressing plate 431 is stationary, and the receiving plate 421 rises to the preset position. The cardboard piece 102 is transferred to the lower side of the pressing plate 431 and the upper side of the receiving plate 421, that is, between the pressing plate 431 and the receiving plate 421. After the receiving plate 421 receives the cardboard piece 102 in place, the pressing plate 431 and the receiving plate 421 move downwards at the same time to press the cardboard piece 102 into the mold box of the next station. Subsequently, the pressing plate 431 rises and the receiving plate 421 remains stationary, waiting for the next cardboard piece 102 to be transferred to the position.

[0086] Step S400: Repeat steps S100-S300.

[0087] This cardboard cutting, pre-folding, and transfer method utilizes the sequential operation of the cutting component 22, pre-folding component 23, slitting component 32, transfer component 33, paper receiving component 42, and paper pressing component 43 to achieve fully automated operation of the cardboard tape 101, including cutting, pre-folding, slitting, transfer, and pressing. This significantly reduces the time spent connecting each process, avoids manual feeding and transfer operations, saves labor costs at the source, and ensures the processing accuracy and quality consistency of the cardboard sheet 102, thereby improving the processing efficiency of the cardboard sheet 102.

The first gear 222 is fixed to the end of the first shaft 221, and the auxiliary bushing 223 is sleeved on the first shaft. 221; The second shaft 224 extends in the front-rear direction and is rotatably disposed on the left side of the lower support 242. The second gear 225 is fixed to the end of the second shaft 224. The cutting wheel 226 is sleeved on the second shaft 224 and is correspondingly disposed with the auxiliary bushing 223. The transmission gear 212 meshes with the second gear 225, and the second gear 225 meshes with the first gear 222. The rotation of the transmission gear 212 drives the second gear 225 and the first gear 222 to rotate in opposite directions, driving the second shaft 224 and the first shaft 221 to rotate in opposite directions, thereby driving the cooperating cutting wheel 226 and the auxiliary bushing 223 to rotate in opposite directions, cutting the paper tape 101 clamped between the cutting wheel 226 and the auxiliary bushing 223. The first motor 211 drives the cutting wheel 226 and the auxiliary bushing 223 to rotate in opposite directions through the meshing of the transmission gear 212, the second gear 225 and the first gear 222. This ensures that the paper tape 101 completes precise cutting in the conveying and clamping state, improves the regularity of the cutting edge 1020, simplifies the transmission link, reduces the probability of failure, and ensures the stable and efficient progress of the cutting process.

[0089] like Figure 5 As shown, in this embodiment, the cutting assembly 22 includes two cutting wheels 226 and two auxiliary rollers 223, with each cutting wheel 226 corresponding to one of the auxiliary rollers 223. This allows for simultaneous cutting of two target positions on the cardboard tape 101, forming two sets of cuts 1020 in a single operation, significantly improving the efficiency of the cutting process. Simultaneously, the two auxiliary rollers 223 provide balanced support for the cardboard tape 101, effectively preventing misalignment and wrinkling during cutting and ensuring the consistency of dimensional accuracy and regularity of the two cuts 1020. In other embodiments, the number of cutting wheels 226 and auxiliary rollers 223 can be three, four, five, etc., and no specific limitation is made here.

[0090] It is worth noting that the auxiliary roller 223 and the cutting roller 226 can cut the cuts 1020 on the three adjacent cardboard pieces 102 on the cardboard tape 101 with each rotation, which greatly increases the effective workload and significantly shortens the processing cycle of a single batch of cardboard pieces 102, thus meeting the high-efficiency operation requirements of mass production.

[0091] like Figure 3 , Figure 4 , Figures 6-8 As shown, the pre-folding assembly 23 includes a third shaft 231, a third gear 232, an upper folding wheel 233, a fourth shaft 234, a fourth gear 235, and a lower folding wheel 236. The third shaft 231 extends in the front-rear direction and is rotatably disposed on the right side of the upper support 241. The third gear 232 is fixed to the end of the third shaft 231, and the upper folding wheel 233 is sleeved on the third shaft 231. The fourth shaft 234 extends in the front-rear direction and is rotatably disposed on the right side of the lower support 242. The fourth gear 235 is fixed to the end of the fourth shaft 234, and the lower folding wheel 236 is sleeved on the fourth shaft 234. 34, corresponding to the upper folding wheel 233, and the lower folding wheel 236 is provided with a folding angle 2360; the transmission gear 212 meshes with the fourth gear 235, the fourth gear 235 meshes with the third gear 232, the rotation of the transmission gear 212 drives the fourth gear 235 and the third gear 232 to rotate in opposite directions, driving the fourth shaft 234 and the third shaft 231 to rotate in opposite directions, thereby driving the cooperating lower folding wheel 236 and upper folding wheel 233 to rotate in opposite directions, so that the edge of the cardboard tape 101 passing between the folding angle 2360 and the upper folding wheel 233 is pre-folded. The first motor 211 drives the upper folding wheel 233 and the lower folding wheel 236 to rotate in opposite directions through the meshing of the transmission gear 212, the fourth gear 235 and the third gear 232. With the folding angle 2360 on the lower folding wheel 236, it ensures that the edge of the cardboard tape 101 is accurately pre-folded, ensuring that the pre-folding angle is consistent and the shape is regular. At the same time, the pre-folding component 23 and the cutting component 22 share the first drive component, which simplifies the device structure, shortens the process connection time, and improves the overall efficiency and stability of cardboard processing.

[0092] like Figure 6 As shown, the pre-folding component 23 includes two upper folding wheels 233 and two lower folding wheels 236, which are matched one-to-one. This allows for simultaneous symmetrical and regular pre-folding of both sides of the paper tape 101, avoiding the problems of offset and inconsistent pre-folding shapes caused by single-sided step-by-step pre-folding. This ensures the dimensional accuracy and consistency of the pre-folded paper tape 101, while also improving pre-folding efficiency.

[0093] like Figure 3 and Figure 4 As shown, the cutting component 22 and the pre-folding component 23 are arranged symmetrically on the left and right sides. This ensures that the paper tape 101 is subjected to balanced force on the conveying path, avoiding problems such as offset and wrinkles caused by force applied by a single-sided mechanism. It also optimizes the structural layout, reduces the space occupied by the device, facilitates connection with the subsequent slitting and transfer mechanism 3, and improves the smoothness of the overall processing flow.

[0094] like Figure 9 and Figure 10As shown, the second drive assembly 31 includes a second motor, a rotating shaft 311, and a flange cam 312. The output end of the second motor is connected to one end of the rotating shaft 311 for transmission. The flange cam 312 is sleeved on the rotating shaft 311 and fixedly connected to the rotating shaft 311. The slitting assembly 32 includes a transmission link 321, a first roller 3221, a second roller 3222, a bearing pad 323, a movable cutter 324, an L-shaped fixed seat 325, a paper pressing block 326, and a fixed cutter 327. The transmission link 321 extends in the vertical direction. The first roller 3221 and the second roller 3222 are spaced apart on the upper and lower sides of the edge of the flange cam 312 and are rotatably mounted on one end of the transmission link 321. The other end of the transmission link 321 away from the first roller 3221 and the second roller 3222 is connected to the bearing pad 323. The movable cutter 324 is fixed on the bearing pad 323. The L-shaped fixed base 325 is fixedly connected to the frame 1, and a slot is reserved on it for the passage of the paper tape 101. The other end of the rotating shaft 311 is rotatably connected to the L-shaped fixed base 325. The paper pressing block 326 is fixed above the L-shaped fixed base 325 and located above the bearing pad 323, and is used to press the paper tape 101 that passes through the slot and is located on the bearing pad 323. The fixed cutter 327 is installed on the paper pressing block 326 and is vertically aligned with the cutting edge of the movable cutter 324. The second motor can drive the rotating shaft 311 to rotate, which drives the flange cam 312 to rotate eccentrically. The first roller 3221 and the second roller 3222 move synchronously with the edge of the flange cam 312, which drives the transmission link 321 to reciprocate in the vertical direction, so that the movable cutter 324 reciprocates in the vertical direction relative to the fixed cutter 327, so that the paper tape 101 passing through the fixed cutter 327 and the movable cutter 324 is cut into paper pieces 102. The flange cam 312 is configured with an eccentric transmission structure with the first roller 3221 and the second roller 3222. This structure drives the moving cutter 324 to reciprocate stably and accurately relative to the fixed cutter 327. This, together with the pressure block 326, presses and fixes the cardboard tape 101, preventing the cardboard tape 101 from shifting or curling during slitting. This ensures the cutting accuracy and edge regularity of the cardboard sheet 102, simplifies the transmission chain, and improves the response speed and stability of the slitting action.

[0095] In this embodiment, the cutting edge shapes of the movable cutter 324 and the fixed cutter 327 are consistent with the finished shape of the cardboard sheet 102. The cardboard sheet 102 conforming to specifications is formed in one step during the slitting process, eliminating subsequent shaping and trimming processes, shortening the processing flow, and improving the finished product qualification rate and quality stability of the cardboard sheet 102.

[0096] like Figure 9As shown, the slitting assembly 32 also includes a connecting plate 328 and a paper pressing component 329. The connecting plate 328 is fixed to the paper pressing block 326, and the paper pressing component 329 is fixed to the connecting plate 328 and located above the support pad 323. It can press against the cardboard strip 101 located on the support pad 323 during the slitting operation to make the cut of the cardboard strip 101 after slitting smooth. During the slitting operation, the paper pressing component 329 connected to the connecting plate 328, together with the paper pressing block 326, can form a double pressing and fixation on the cardboard strip 101 on the support pad 323, to prevent the cardboard strip 101 from bending, curling, and shifting during the cutting process of the moving cutter 324 and the fixed cutter 327, to ensure that the cut of the cardboard strip 101 after slitting is smooth and flat, improve the edge quality of the cardboard sheet 102, and ensure the consistency of the finished product.

[0097] like Figure 9 As shown, in this embodiment, the slitting assembly 32 includes two paper pressing components 329, which are spaced apart along the front-to-back direction and symmetrically arranged on both sides of the support pad 323. The two paper pressing components 329 provide balanced double-sided pressure and fixation to the cardboard strip 101, preventing unilateral deviation or curling of the cardboard strip 101 during slitting, ensuring that the cardboard strip 101 remains flat throughout the cutting process, and significantly improving the regularity and dimensional consistency of the cut of the cardboard sheet 102.

[0098] like Figure 9 As shown, the slitting assembly 32 also includes a paper feed guide plate 320, which is installed at the slot of the L-shaped fixing seat 325. The paper feed guide plate 320 has a curved guide surface 3201, which is used to guide the paper tape 101 into the slot. The curved guide surface 3201 of the paper feed guide plate 320 smoothly guides the paper tape 101, avoiding jamming, wrinkling or deviation when the paper tape 101 enters the slot. This ensures that the paper tape 101 enters the slot with a precise posture and fits against the support pad 323, providing a stable prerequisite for the subsequent precise slitting of the moving cutter 324 and the fixed cutter 327, and improving the smoothness and stability of the slitting process.

[0099] like Figure 10As shown, the second drive assembly 31 also includes a first cam 313, which is located below and spaced apart from the flange cam 312. The first cam 313 is sleeved on the rotating shaft 311 and fixedly connected to it. The first cam 313 has a first eccentric annular groove 3130. The transfer assembly 33 includes a first follower wheel 331, a rotating shaft 332, a first transmission rod 333, a connecting block 334, a mounting shaft 335, and an adsorption component 336. The first follower wheel 331 is slidably disposed in the first eccentric annular groove 3130. The rotating shaft 332 extends in the vertical direction. One end of the first transmission rod 333 is connected to the first follower wheel 331. The first motor is a moving connection, with its other end rotatably connected to one end of the rotating shaft 332, and the other end of the rotating shaft 332 connected to the connecting block 334; the mounting shaft 335 is connected to the connecting block 334, and the adsorption element 336 is sleeved on the mounting shaft 335 for adsorbing the cut cardboard pieces 102 on the lower bearing pad 323; the second motor can drive the rotating shaft 311 to rotate, thereby driving the first cam 313 to rotate eccentrically, and the first follower wheel 331 to move along the first eccentric ring groove 3130, thereby driving the first transmission rod 333, the rotating shaft 332, the connecting block 334 and the mounting shaft 335 to rotate, so as to transfer the adsorption element 336 and the cardboard pieces 102 adsorbed on it to the paper receiving and pressing mechanism 4. Through the eccentric transmission between the first cam 313 and the first eccentric ring groove 3130, the first follower wheel 331, the first transmission rod 333, the rotating shaft 332, and the connecting block 334 are driven to work together to drive the adsorption component 336 to accurately complete the adsorption and transfer action of the cardboard piece 102. After the cardboard piece 102 is transferred to the correct position, it can return to the initial position and repeat the action. At the same time, the transfer component 33 and the slitting component 32 share the second drive component 31, which greatly simplifies the number of drive components, reduces the structural space of the device, and achieves seamless connection between the slitting and transfer processes, thereby improving the automation level and work efficiency of cardboard processing.

[0100] like Figure 10 As shown, the transfer assembly 33 includes two adsorption elements 336, which are spaced apart along the front-to-back direction and symmetrically arranged on both sides of the support pad 323 to evenly adsorb both sides of the cardboard sheet 102. The two adsorption elements 336 form a balanced bilateral adsorption force on the cardboard sheet 102, preventing the cardboard sheet 102 from warping, shifting, or falling off on one side during the transfer process, ensuring that the cardboard sheet 102 is flat and stable, and accurately transferred to the paper receiving and pressing mechanism 4, thereby improving the reliability and accuracy of the transfer action.

[0101] like Figures 11-12As shown, the third drive assembly 41 includes a third motor, a support plate 411, a drive shaft 412, and a second cam 413. The support plate 411 is fixed to the frame 1. The drive shaft 412 extends in the left-right direction. One end of the drive shaft 412 is connected to the output end of the third motor, and the other end is rotatably connected to the support plate 411. The second cam 413 is sleeved on the drive shaft 412 and fixedly connected to the drive shaft 412. The second cam 413 is provided with a second eccentric ring groove 4130. The paper pressing assembly 43 also includes a second follower wheel 432, a U-shaped connecting rod 433, and a first linkage rod 434. The second follower wheel 432 is slidably disposed in the second eccentric ring groove 4130. The U-shaped connecting rod 433 is connected to the support plate 411. The first linkage rod 434 extends vertically, and one arm of the U-shaped connecting rod 433 is rotatably connected to the second follower wheel 432, while the other arm is connected to one end of the first linkage rod 434. The other end of the first linkage rod 434 is connected to the pressure plate 431. The third motor can drive the transmission shaft 412 to rotate, causing the second cam 413 to rotate eccentrically. The second follower wheel 432 moves along the second eccentric annular groove 4130, causing the U-shaped connecting rod 433 to rotate relative to the support plate 411. This causes the first linkage rod 434 to reciprocate vertically, and the pressure plate 431 to reciprocate vertically synchronously, pressing the cardboard sheet 102 downwards into the mold box of the next station. Through the eccentric transmission of the second cam 413 and the second eccentric ring groove 4130, the second follower wheel 432, the U-shaped connecting rod 433 and the first linkage rod 434 are driven to move together, thereby driving the pressing plate 431 to accurately complete the up and down reciprocating motion, so as to realize the stable pressing and feeding of the card sheet 102 to the mold box; at the same time, the pressing assembly 43 and the receiving assembly 42 share the third drive assembly 41, which simplifies the number of drive components, improves the accuracy and stability of the pressing and feeding action, and ensures smooth process connection.

[0102] like Figure 11 As shown, the paper pressing assembly 43 also includes a guide seat 435, a connecting seat 436, and an adapter block 437. The guide seat 435 is fixed to the frame 1. The first linkage rod 434 passes through the guide seat 435 and is connected to the connecting seat 436. The adapter block 437 is connected to the connecting seat 436 and the pressing plate 431. The guide seat 435 provides precise guidance for the reciprocating motion of the first linkage rod 434, preventing deviation and shaking during the movement. Combined with the stable connection between the connecting seat 436 and the adapter block 437, it ensures that the pressing plate 431 always maintains a stable movement posture, ensuring uniform pressure and accurate positioning on the cardboard sheet 102, effectively improving the stability and consistency of pressing the cardboard sheet 102 into the mold box.

[0103] like Figures 11-12As shown, the third drive assembly 41 also includes a third cam 414, which is located to the left of the second cam 413 and spaced apart from it. The third cam 414 is sleeved on the drive shaft 412 and fixedly connected to it. The third cam 414 is provided with a third eccentric annular groove 4140. The paper receiving assembly 42 also includes a third follower wheel 422, a second drive rod 423, a connector 424, and a second linkage rod 425. The third follower wheel 422 is rotatably connected to the second drive rod 423 and slidably disposed in the third eccentric annular groove 4140. One end of the second drive rod 423 is connected to the support plate 411. The first motor is connected to the second motor, and the second motor is rotatably connected to one end of the connector 424. The second linkage rod 425 extends in the vertical direction, and one end of the second linkage rod 425 is rotatably connected to the other end of the connector 424. The other end of the second linkage rod 425 is connected to the receiving plate 421. The third motor can drive the transmission shaft 412 to rotate, which drives the third cam 414 to rotate eccentrically. The third follower wheel 422 moves along the third eccentric ring groove 4140, which drives the second transmission rod 423 to rotate relative to the support plate 411. This drives the connector 424, the second linkage rod 425 and the receiving plate 421 to reciprocate in the vertical direction to catch the transferred cardboard piece 102. Through the eccentric transmission of the third cam 414 and the third eccentric ring groove 4140, the third follower wheel 422, the second transmission rod 423 and the second linkage rod 425 are driven to move in an orderly manner, driving the paper splicing plate 421 to accurately complete the up and down reciprocating motion, so as to achieve stable reception of the cardboard sheet 102; at the same time, the paper splicing assembly 42 and the paper pressing assembly 43 share the third drive assembly 41, simplifying the configuration of drive components, improving the accuracy and stability of the paper splicing action, and ensuring the seamless connection of the paper splicing and pressing process.

[0104] like Figure 11 As shown, in this embodiment, the second linkage rod 425 passes through the guide seat 435 and is connected to the receiving plate 421. The guide seat 435 provides precise guidance and limitation for the up-and-down reciprocating motion of the second linkage rod 425, preventing deviation and shaking during the movement, ensuring that the receiving plate 421 always maintains a stable movement posture, and ensuring that the receiving plate 421 can accurately receive the transferred cardboard piece 102, improving the accuracy and stability of the paper receiving action. At the same time, the single guide seat 435 guides the first linkage rod 434 and the second linkage rod 425, simplifying the component configuration and optimizing the device layout.

[0105] like Figure 10 and Figure 11As shown, the mold box includes a fixing block 51 and a fixing plate 52. The fixing block 51 is fixed to the frame 1 and has a first clearance opening 510. The end of the rotating shaft 332 facing away from the first cam 313 passes through the first clearance opening 510 and is connected to the connecting shaft block 334. The fixing plate 52 is fixedly installed on the fixing block 51 and has a second clearance opening 520. The pressing plate 431 and the receiving plate 421 are both adapted to be located in the second clearance opening 520. The first clearance opening 510 on the fixing block 51 provides a stable space for the rotating shaft 332 to pass through and rotate, avoiding interference between the rotating shaft 332 and the fixing block 51 when it moves. The second clearance opening 520 on the fixing plate 52 provides precise movement limits for the pressing plate 431 and the receiving plate 421, ensuring that they can smoothly complete the receiving and pressing action of the card sheet 102, while optimizing the compactness of the overall device and improving the stability and smoothness of operation.
