Description

Technical Field

[0001] This utility model relates to the field of tissue stacking technology, specifically to a tissue double-row stacking device. Background Technology

[0002] In current wet wipe processing, which involves stacking and transporting paper towels, it is necessary to solve the problems of efficient stacking and group conveying to improve production efficiency. Currently, most methods involve intermittent stops of the conveyor belt, during which paper towels are stacked. The stacking time ends when the stop is complete, and then the fabric and paper materials are conveyed. This results in equipment downtime and high waste rates. Existing patent "A Novel Double-Row Fabric Feeding Assembly (Authorization Announcement No. CN218707892U)" discloses a novel double-row fabric feeding assembly, including a feeding board with multiple conveyor belts for transporting stacked materials. The feeding board forms guide grooves, and the gaps between the guide grooves and the conveyor belts correspond. A lifting and lowering receiving plate assembly is arranged in the guide grooves. A pre-connecting plate assembly is arranged on one side of the feeding board, and the pre-connecting plate assembly delivers the stacked materials to the upper end of the receiving plate assembly. The receiving plate assembly includes multiple receiving forks, which are fitted with guide grooves with a clearance, allowing them to move up and down along the guide grooves. The upper surfaces of the multiple receiving forks are coplanar and move up and down synchronously, forming a receiving surface. A guide groove B is formed in the receiving plate assembly, through which the pre-attached fork can pass. While this solution solves the problem of intermittent belt stops during tissue stacking, it achieves a double-cross structure using pre-attached and receiving forks. This allows pre-attached fabric to be placed on the completed receiving fork, and a certain number of fabrics to be delivered onto the conveyor belt through the intersection of the receiving forks and the conveyor belt. While the receiving forks deliver the fabric to the conveyor belt, the pre-attached forks pre-attach the fabric, improving the efficiency of fabric receiving and feeding to some extent through this alternating process. However, this solution is complex, costly to manufacture, requires multiple conveyor belts, and cannot promptly remove waste during production. Therefore, a new tissue stacking device needs to be designed to address these issues. Summary of the Invention

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects in the prior art, thereby providing a tissue stacking device.

[0004] A tissue stacking device includes: a circulating fabric receiving horizontal mechanism, a circulating fabric receiving vertical mechanism, a discharging fabric receiving horizontal mechanism, and a discharging fabric receiving vertical mechanism; the circulating fabric receiving horizontal mechanism is mounted on the circulating fabric receiving vertical mechanism; the discharging fabric receiving horizontal mechanism is mounted on the discharging fabric receiving vertical mechanism; the circulating fabric receiving horizontal mechanism includes a toothed plate for receiving tissues cut by an upper cutting roller; the circulating fabric receiving vertical mechanism controls the lifting and lowering of the circulating fabric receiving horizontal mechanism; the discharging fabric receiving horizontal mechanism includes a receiving conveyor belt and a baffle, the baffle including baffle posts located directly below the toothed plate, the baffle posts corresponding to the tooth gaps of the toothed plate; the receiving conveyor belt transports the tissues conveyed from the toothed plate to the next process in the production line.

[0005] Furthermore, the teeth on the toothed plate are divided into two groups, and the corresponding baffles are also divided into two groups. The gaps on each group of toothed plates correspond to the baffles in each group, and each group of teeth corresponds to a row of paper towels, enabling double-row stacking. Each group of teeth has 4 teeth with 4 gaps between them, and each group of baffles has 4 baffles.

[0006] Furthermore, the stacking device also includes a stacking and unloading conveyor, which is located on the right side of the fabric conveyor belt and is used to convey the paper towels conveyed by the conveyor belt.

[0007] Furthermore, a stacking and shaping mechanism is provided above the stacking and unloading conveyor for pressing the paper towels neatly. Furthermore, the stacking and unloading conveyor includes two telescopic belts. Furthermore, a shaping induction photoelectric sensor is also provided on the stacking and unloading conveyor, and the shaping induction photoelectric sensor is positioned at a corresponding location on the stacking and shaping mechanism.

[0008] Furthermore, the material blocking fence includes a horizontal plate base, which is disposed on the side wall of the discharge receiving transverse mechanism and located above the discharge belt, and the material blocking column is fixed on the horizontal plate base.

[0009] Furthermore, the stacking and shaping mechanism includes a shaping plate for shaping stacked tissues.

[0010] Furthermore, the stacking and discharging conveyor also includes a telescopic cylinder and a differential wheel set. The differential wheel set achieves the speed difference between the two conveyor belts at the discharge point through the speed ratio difference of the transmission wheels. When the paper towels are conveyed to the outlet, the two sets of paper towels are staggered by a distance and discharged sequentially.

[0011] The working principle of this tissue stacking device is as follows:

[0012] S1: The cutter roller cuts and folds the paper towels, and the first paper towel is picked up by the toothed receiving plate of the circulating receiving mechanism. At the same time, the circulating receiving vertical mechanism drives the circulating receiving horizontal mechanism to move downward. The downward movement distance is equal to the thickness of the paper towel, so as to continuously pick up the folded and cut paper towels and stack them at the same time. The downward movement of the circulating receiving horizontal mechanism is synchronized with the cutter roller cutting and folding the paper towels. After each paper towel is folded, the horizontal mechanism moves downward by the corresponding thickness of the paper towel.

[0013] S2: The vertical discharging and receiving mechanism drives the horizontal discharging and receiving mechanism to move upward. When it reaches the toothed receiving plate of the horizontal recirculation receiving mechanism, the required number of tissues is stacked. The material blocking post of the material blocking fence is inserted into the gap between the teeth of the toothed receiving plate, and the material blocking fence is located on the left side of the stacked tissues. The toothed receiving plate of the horizontal recirculation receiving mechanism retracts outward. The vertical discharging and receiving mechanism moves downward synchronously with the vertical recirculation receiving mechanism. The material blocking fence of the horizontal discharging and receiving mechanism leaves the stacked tissues on the conveyor belt of the horizontal discharging and receiving mechanism.

[0014] S3: The vertical mechanism of the circulating cloth receiving device drives the horizontal mechanism of the circulating cloth receiving device to move upward to the waiting position to start stacking. Repeat the actions of steps S1 and S2. Repeating the cycle will achieve the stacking purpose. At the same time, the stacked paper towels are driven downward by the vertical mechanism of the discharge cloth receiving device to move the horizontal mechanism of the discharge cloth receiving device. When the movement reaches the water level position of the belt of the stacking and discharging conveyor, the conveyor on the horizontal mechanism of the discharge cloth receiving device starts, transferring the stacked paper towels to the belt of the stacking and discharging conveyor. After being shaped by the stacking and shaping mechanism, they are conveyed to the packaging machine by differential speed.

[0015] Furthermore, in step S3, a sensor is also installed on the tissue stacking device. After the conveyor starts, when waste material is detected on the belt of the discharge receiving transverse mechanism, the telescopic cylinder of the telescopic belt is activated when the waste material is about to reach the stacking discharge conveying device, so that the telescopic belt is shortened and a gap appears between the discharge receiving transverse mechanism and the telescopic belt. The waste material falls through the gap, preventing the waste material from entering the stacking discharge conveying device, thereby realizing automatic discharge.

[0016] Furthermore, when the shaping photoelectric sensor detects material, the material discharge stops, the shaping cylinder descends to flatten the paper towels, and then the shaping cylinder drives the shaping plate to reset. At the same time, the conveyor belt continues to start; until the next stack of paper towels arrives, the above steps are repeated.

[0017] The technical solution of this utility model has the following advantages:

[0018] 1. The paper towel stacking device of this utility model achieves high-speed stacking of paper towels without stopping by coordinating and circulating the horizontal and vertical mechanisms of the circulating cloth receiving mechanism, the horizontal and vertical mechanisms of the discharge cloth receiving mechanism, and the horizontal and vertical mechanisms of the discharge cloth receiving mechanism, thereby improving work efficiency.

[0019] 2. The paper towel stacking device of this utility model, through the cooperation of the material feeding and receiving transverse mechanism and the stacking and discharging conveyor, realizes the paper towel feeding, automatic waste discharge, and automatic differential merging function.

[0020] 3. The paper towel stacking device of this utility model has a simple structure, low manufacturing cost, energy saving and emission reduction, and the equipment is modular, making maintenance and replacement convenient. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] Example 1

[0032] like Figure 1-4A tissue stacking device includes: a circulating cloth receiving horizontal mechanism 1, a circulating cloth receiving vertical mechanism 2, a discharging cloth receiving horizontal mechanism 3, and a discharging cloth receiving vertical mechanism 4; the circulating cloth receiving horizontal mechanism 1 is mounted on the circulating cloth receiving vertical mechanism 2; the discharging cloth receiving horizontal mechanism 3 is mounted on the discharging cloth receiving vertical mechanism 4; the circulating cloth receiving horizontal mechanism includes a toothed cloth receiving plate 11, which is used to receive the tissues cut by the upper cutting roller 5. The specific structure of the cutting roller 5 and how it cuts and folds the tissues are mature existing technologies and will not be described in detail here. The circulating cloth receiving vertical mechanism 2 controls the lifting and lowering of the circulating cloth receiving horizontal mechanism 1, facilitating the stacking of paper towels. The discharging cloth receiving vertical mechanism 4 controls the lifting and lowering of the discharging cloth receiving horizontal mechanism 3, facilitating the discharging cloth receiving horizontal mechanism 3 to receive paper towels from the toothed cloth receiving plate 11. The discharging cloth receiving horizontal mechanism 3 includes a cloth receiving conveyor belt 31 and a baffle 32. The baffle 32 includes a baffle post 321, which is located directly below the toothed cloth receiving plate 11 and close to the left side of the toothed cloth receiving plate. The baffle post 321 corresponds to the tooth gap of the toothed cloth receiving plate. The cloth receiving conveyor belt 31 is used to transport the paper towels stacked from the toothed cloth receiving plate to the next device on the production line, namely the stacking and discharging conveyor device 8. The discharging cloth receiving vertical mechanism 4 includes a discharging servo screw module 41, which controls the lifting and lowering of the discharging cloth receiving horizontal mechanism 3. The transverse feeding and receiving mechanism 3 includes a sliding frame 34, with the feeding conveyor belt 31 and side wall 33 fixedly connected to the sliding frame 34. The sliding frame 34 is sleeved and fixed on the feeding servo screw module 41. The feeding servo screw module 41 drives the sliding frame 34 to move up and down, thereby driving the feeding conveyor belt 31, side wall 33, and baffle 32 to move up and down together. A conveyor motor 35 is also fixed on the sliding frame 34. The conveyor motor 35 is connected to the drive shaft of the feeding conveyor belt 31 and is used to drive the rotation of the feeding conveyor belt 31.

[0033] Furthermore, the teeth on the toothed receiving plate 11 are divided into two groups, and the corresponding baffle posts 321 are also divided into two groups. The gaps on each group of toothed receiving plates correspond to the corresponding baffle posts 321. Each group of teeth corresponds to a row of paper towels, which can achieve double-row stacking and improve work efficiency. Furthermore, each group of teeth on the toothed receiving plate 11 has 4 teeth and 4 gaps between them, and each group of baffle posts also has 4 baffle posts 321, with the 4 baffle posts 321 corresponding to the 4 gaps between the teeth.

[0034] Furthermore, the circulating fabric splicing transverse mechanism 1 also includes a transverse screw module 12, on which the toothed fabric splicing plate 11 is fixed. The transverse screw module 12 can control the transverse power of the toothed fabric splicing plate 11. The circulating fabric splicing vertical mechanism 2 includes a vertical screw module 21, used to control the up-and-down movement of the circulating fabric splicing transverse mechanism 1. Furthermore, a waterproof cover 13 is also provided on the outside of the circulating fabric splicing transverse mechanism 1 and the circulating fabric splicing vertical mechanism 2. The waterproof cover 13 can be made of transparent plastic material to facilitate observation of the internal equipment operation.

[0035] Furthermore, the stacking and unloading conveyor 8 is located on the right side of the fabric receiving conveyor belt 31 and is used to receive the paper towels conveyed by the fabric receiving conveyor belt 31.

[0036] Furthermore, a stacking and shaping mechanism 6 is provided above the stacking and discharging conveyor 8 to press the paper towels neatly.

[0037] Furthermore, the stacking and unloading conveying device 8 includes two conveyor belts for conveying double rows of paper towels.

[0038] Furthermore, the stacking and discharging conveying device 8 is also equipped with a shaping induction photoelectric sensor 7, which is located at a corresponding position on the stacking and shaping mechanism 6. Specifically, the shaping induction photoelectric sensor 7 is installed on the discharging conveying side wall 82 of the stacking and discharging conveying device 8. Furthermore, the material blocking fence includes a horizontal plate base 322, which is located on the side wall 33 of the discharge receiving transverse mechanism 3 and above the receiving conveyor belt 31. The material blocking post 321 is fixed on the horizontal plate base 322, and the horizontal plate base 322 is detachably installed above the side wall 33.

[0039] Example 2

[0040] like Figure 1-2 5. Based on Embodiment 1, a further improvement is made: the two conveyor belts 81 of the stacking and discharging conveyor device 8 are telescopic belts. The two conveyor belts 81 extend and retract synchronously, with the telescopic end close to the side of the discharge receiving transverse mechanism 3. The telescopic belts in this embodiment can utilize mature existing technology. The stacking and discharging conveyor device 8 also includes a telescopic cylinder 83 and a differential wheel set 84. The telescopic cylinder 83 can control the extension and retraction of the conveyor belts. When waste or debris needs to be discharged, the controller controls the conveyor belt 81 to shorten. After the waste falls, the conveyor belt 81 returns to its original position, thus preventing waste from being removed from the production line in a timely manner and improving production efficiency. The specific system control and foreign object recognition are mature existing technology algorithms and will not be specifically commented on. The differential wheel set 84 achieves a speed difference between the two conveyor belts 81 at the discharge point through the transmission wheel speed ratio difference. When the paper towels are conveyed to the outlet, the two sets of paper towels are staggered by a distance, discharging sequentially.

[0041] Furthermore, the stacking and shaping mechanism 6 includes a shaping plate 61 and a shaping cylinder 62. The shaping plate 61 is used to shape the stacked tissues. When the shaping induction photoelectric sensor 7 detects material, the material discharge stops, the shaping cylinder 62 descends to flatten the tissues, and then the shaping cylinder 62 drives the shaping plate 61 to reset. At the same time, the conveyor belt 81 continues to start; until the next stacked tissues arrive, the above steps are repeated.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
