Description

Technical Field

[0001] This invention relates to the field of folding machine technology, specifically to a multifunctional small linen folding machine structure and its usage method. Background Technology

[0002] Small linen folding machines are devices used to automatically fold small linen items such as pillowcases and napkins. They are mainly suitable for laundry facilities in hotels, hospitals, and large laundry plants. Small linen folding machines are generally used in conjunction with ironing machines, effectively replacing manual folding operations, preventing burns, reducing labor costs, and decreasing labor intensity.

[0003] Currently, the industry's demand for folding methods for small linens is primarily for double horizontal folds and cross folds. However, few folding machines in the industry can simultaneously perform both double horizontal and cross folds. The common method for achieving cross folds is still manual labor, which is costly and inefficient. While some alternatives involve adding dedicated vertical folding and stacking equipment at the downstream stage, this method is expensive to purchase, requires a large area, and is costly to maintain. Furthermore, the output channels for the two folding methods cannot be aligned, making downstream linen collection difficult and failing to adequately address customer needs. Therefore, developing a small linen folding machine capable of simultaneously performing double horizontal and cross folds has become a pressing problem. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multifunctional small linen folding machine structure and its usage method. The structure is compact and easy to maintain. It realizes the integrated design of double horizontal folding and cross folding functions, and the two folding methods can share the same output channel, which greatly reduces the difficulty of manual collection and the difficulty of subsequent automation upgrades, and saves floor space and equipment costs.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The innovative feature of the multifunctional small-item linen folding machine structure of the present invention is that it includes a base, a shell, an upper conveying mechanism, a first air jet assembly, a middle conveying mechanism, a second air jet assembly, a lower conveying mechanism, a longitudinal folding conveying mechanism, and a stacking conveying mechanism; a shell with an open lower surface is integrally formed on the left side of the upper surface of the horizontally arranged base, and the upper conveying mechanism, the middle conveying mechanism, and the lower conveying mechanism are arranged sequentially from top to bottom inside the shell; the upper conveying mechanism and the middle conveying mechanism are both inclined towards the upper right, and a [missing information - likely a design feature] is provided on the right side between their right ends. There is a first jet assembly, which blows air to fold the linens that are being transported to the upper right direction by the upper conveyor mechanism into a horizontal fold, and then transports them to the lower left direction by the middle conveyor mechanism. The lower conveyor mechanism is horizontally arranged, and inside the housing, from left to right, there is a longitudinal folding conveyor mechanism and a stacking conveyor mechanism. A second jet assembly is located on the left side between the left ends of the middle conveyor mechanism and the lower conveyor mechanism. By selecting the blowing time of the second jet assembly and cooperating with the longitudinal folding conveyor mechanism, the double horizontal folding and cross folding functions can be switched. The stacking conveyor mechanism then flattens the folded linens.

[0006] Preferably, the upper conveying mechanism includes a first hinge seat, an adjusting rod, a first rotating shaft, a second hinge seat, a first cylinder, a second rotating shaft, a third rotating shaft, a fourth rotating shaft, a first adjusting roller, and an upper conveyor belt; a fixed plate is symmetrically arranged vertically and horizontally on the left side of the housing relative to the lower conveying mechanism, and a first hinge seat is symmetrically arranged vertically and horizontally on the left side of the housing relative to the position above the fixed plate, and a second hinge seat is symmetrically arranged vertically and horizontally on the left side of the housing relative to the position below the fixed plate; an adjusting rod is also horizontally arranged on the left side of each first hinge seat. Each of the adjusting rods has its right end extending obliquely to the upper right and is vertically and laterally rotatably connected to the corresponding first hinge seat. A first rotating shaft is also provided horizontally and longitudinally between the left ends of the two adjusting rods. A first cylinder is also provided vertically between each second hinge seat and the corresponding adjusting rod. The tail of each first cylinder is vertically and laterally rotatably connected to the corresponding second hinge seat, and its extension and retraction ends are all obliquely arranged to the upper left and vertically and laterally rotatably connected to the corresponding position on the lower surface of the adjusting rod. Thus, under the drive of the first cylinder, the first rotating shaft rotates vertically around the housing with the adjusting rod. Inside the housing, at the upper right position, a second and third rotating shaft are horizontally and longitudinally arranged, spaced apart on both sides. The lower end of the second rotating shaft is located above the upper end of the first rotating shaft. The lengths of the second and third rotating shafts are matched with the length of the first rotating shaft. The two ends of the second and third rotating shafts are respectively rotatably connected to the front and rear inner surfaces of the housing around their own axial direction. A fourth rotating shaft, matching the length of the first rotating shaft, is also horizontally and longitudinally arranged at the upper end between the two fixed plates. Several upper conveyor belts are arranged longitudinally and spaced apart, with each upper conveyor belt looping around the first rotating shaft in a ring. The upper conveyor belt, consisting of a first, second, third, and fourth rotating shaft, transports the linens fed from the feeder to the upper right direction via clockwise rotation. A first adjusting roller is horizontally and longitudinally positioned on the left side of the upper conveyor belt, located between the first and fourth rotating shafts. The length of the roller surface of the first adjusting roller matches the length of the first rotating shaft. After the first adjusting roller is positioned, its two ends are screwed to the left side of the front and rear inner surfaces of the housing, ensuring that the roller surface of the first adjusting roller can rotate around its own axial direction. This allows for tension adjustment of the upper conveyor belt and ensures that the housing does not interfere with the movement of the upper conveyor belt in transporting the linens.

[0007] Preferably, the intermediate conveying mechanism includes a fifth rotating shaft, a sixth rotating shaft, a seventh rotating shaft, a guide roller, a second adjusting roller, a third adjusting roller, and an intermediate conveyor belt; inside the housing, a fifth rotating shaft is horizontally and longitudinally rotatable relative to the fourth rotating shaft, and inside the fifth rotating shaft, a seventh rotating shaft of matching length is horizontally and longitudinally rotatable relative to the lower left of the third rotating shaft, the seventh rotating shaft being positioned close to the third rotating shaft, and its lower end being above the horizontal plane of the upper end of the fifth rotating shaft; several intermediate conveyor belts are arranged longitudinally at intervals, and each intermediate conveyor belt is annular. Connected to the fifth and seventh rotating shafts, the counter-clockwise rotation of the middle conveyor belt transports the linen, after a horizontal fold, to the lower left. The upper conveyor belt, located between the third and fourth rotating shafts, flattens the linen transported by the middle conveyor belt. On the lower surface of the lower half of the middle conveyor belt, near the seventh rotating shaft, a sixth rotating shaft and a third adjusting roller are horizontally spaced longitudinally. The sixth rotating shaft is positioned to the lower right of the line connecting the centers of the fifth and seventh rotating shafts, and the third adjusting roller is positioned to the upper right of the sixth rotating shaft. The length of the sixth rotating shaft is... The length of the fifth rotating shaft is matched, and its two ends are rotatably connected to the corresponding positions of the front and rear inner surfaces of the housing. The length of the third adjusting roller is matched with the length of the fifth rotating shaft. After the third adjusting roller is positioned, its two ends are screwed and fixed to the corresponding positions of the front and rear inner surfaces of the housing, ensuring that its roller surface can rotate around its own axis. The tension of the middle conveyor belt is then adjusted by the third adjusting roller, ensuring that the housing does not interfere with the movement of the middle conveyor belt in transporting linens. A second adjusting roller is also horizontally and longitudinally arranged on the upper surface of the middle conveyor belt located between the sixth rotating shaft and the third adjusting roller. The two ends of the second adjusting roller are rotatably connected to the corresponding positions of the front and rear inner surfaces of the housing, and the tension of the middle layer conveyor belt is adjusted by adjusting the position of the third adjusting roller and assisting the second adjusting roller; a guide roller is also horizontally and longitudinally provided on the upper surface of the middle layer conveyor belt located between the fifth and sixth rotating shafts near the fifth rotating shaft. The two ends of the guide roller are rotatably connected to the corresponding positions of the front and rear inner surfaces of the housing, and the lower end of the guide roller is located at the lower end of the fifth rotating shaft, and the guide roller guides the middle layer conveyor belt located between the fifth and sixth rotating shafts.

[0008] Preferably, the lower conveying mechanism includes an eighth rotating shaft, a ninth rotating shaft, and lower conveyor belts; inside the housing, an eighth rotating shaft is horizontally and longitudinally rotatable relative to the fifth rotating shaft, and the vertical longitudinal plane containing the left end of the eighth rotating shaft is located to the right of the vertical longitudinal plane containing the left end of the fifth rotating shaft; inside the housing, a ninth rotating shaft, matching the length of the eighth rotating shaft, is horizontally and longitudinally rotatable relative to the right of the eighth rotating shaft; the upper end faces of the eighth and ninth rotating shafts are horizontally coplanar, and several lower conveyor belts are spaced apart longitudinally. The equipment is set up and respectively looped around the eighth and ninth rotating shafts, and then the linens are horizontally transported to the right to the longitudinal folding conveyor mechanism by the clockwise rotation of the lower conveyor belt; the distance between the middle conveyor belt and the lower conveyor belt, located between the fifth rotating shaft and the guide roller, must ensure that the second air jet assembly can blow the first end of the linens after one transverse fold onto the lower conveyor belt for horizontal rightward transport, and at the same time, it must ensure that the second air jet assembly can fold the linens after one transverse fold a second time and blow them onto the lower conveyor belt for horizontal rightward transport.

[0009] Preferably, it further includes a first mounting base and a first guide plate; the upper conveyor belt located between the third and fourth rotating shafts and the middle conveyor belt located between the fifth and seventh rotating shafts are arranged parallel to each other vertically, and the distance between the upper and middle conveyor belts in this section must ensure that the linens conveyed by the middle conveyor belt can be flattened by the upper conveyor belt, and that the upper conveyor belt does not interfere with the conveying action of the middle conveyor belt; the first air jet assembly is located inside the housing on the right side relative to the third and seventh rotating shafts, and several air jet holes I are arranged longitudinally at intervals at its air jet end, ensuring that each air jet hole I is arranged facing left towards the area between the third and seventh rotating shafts; the spraying position of each air jet hole I is corresponding to the position of the first transverse fold crease of the linens located at the third rotating shaft. Correspondingly, the linen located at the third pivot is folded laterally once by the blowing action of the first jet assembly. At the same time, the linen after being folded laterally is transported to the lower left by the middle layer conveyor mechanism. During this process, the linen transported by the middle layer conveyor belt is flattened by the upper layer conveyor belt located between the third and fourth pivots. A first mounting seat is also provided on the inner top surface of the housing relative to the third pivot. The first guide plate is an arc-shaped structure and is coaxially spaced at the upper right position on the outer side of the third pivot. One end of the first guide plate is screwed to the lower end of the first mounting seat, and the other end is set downward. It does not interfere with the movement of the first jet assembly and the upper layer conveyor belt, and thus the linen transported by the upper layer conveyor belt is right-limited by the first guide plate.

[0010] Preferably, it also includes a second mounting base and a second guide plate; the second jet assembly is positioned between the two fixed plates at a position lower to the left of the fourth rotating shaft, and has several jet holes II spaced longitudinally at its jet end, ensuring that each jet hole II is positioned to the right towards the area between the fifth and eighth rotating shafts; the spraying position of each jet hole II corresponds to the position of the second transverse fold crease of the linen located at the fifth rotating shaft, and by selecting the spraying time node of the second jet assembly, the first end of the linen located at the fifth rotating shaft is sprayed onto the lower conveyor belt for horizontal rightward transmission, or the linen located at the fifth rotating shaft is subjected to a second transverse fold crease. After being folded horizontally, the air is sprayed onto the lower conveyor belt for horizontal rightward transport. Inside the housing, between the first adjusting roller and the fifth rotating shaft, there is a second mounting base. Between each pair of adjacent upper conveyor belts, there is an arc-shaped second guide plate. Each second guide plate is coaxially spaced at a position on the upper left side of the fifth rotating shaft. One end of each guide plate is screwed to the lower end of the second mounting base, and the other end of each guide plate is facing downward. The guide plate does not interfere with the movement of the second air jet assembly, the upper conveyor belt, and the middle conveyor belt. Thus, the second guide plate limits the left movement of the linens transported by the middle conveyor belt.

[0011] Preferably, the longitudinal folding conveyor mechanism includes side plates, support plates, mounting plates I, a tenth rotating shaft, a longitudinal folding conveyor belt, a second cylinder, a flip plate, a base plate, and an adsorption plate; on the upper surface of the base, opposite to the right side of the ninth rotating shaft and located inside the housing, there are also vertically and horizontally arranged side plates at intervals, and on the upper end surface of each side plate, there are also vertically and horizontally arranged mounting plates I, the two mounting plates I are symmetrically arranged front and back; between the two mounting plates I, there are also horizontally and longitudinally arranged tenth rotating shafts at intervals, the two tenth rotating shafts are respectively located at the left and right ends of the mounting plates I, and their ends are respectively connected to the inner surface of the corresponding mounting plates I around themselves. Axial rotational connection; several longitudinally folded conveyor belts are respectively arranged in a ring-like manner along the front and rear halves of the two tenth rotating shafts, and the upper surface of each longitudinally folded conveyor belt is horizontally coplanar with the upper surface of the lower conveyor belt, and the linens are horizontally transported to the right by the clockwise rotation of the longitudinally folded conveyor belts; the base plate is horizontally transversely arranged directly above the rear half between the two tenth rotating shafts, and its lower surface is fixedly connected to the upper end face of the rear mounting plate I near the rear, ensuring that the upper surface of the base plate is below the horizontal plane where the upper surface of the longitudinally folded conveyor belts is located. Each longitudinal fold conveyor belt has a vertically embedded and through-cut clearance groove II on its surface, and each clearance groove II is an elongated strip that matches the longitudinal fold conveyor belt. The clearance groove II ensures that the base plate does not interfere with the transmission movement of the longitudinal fold conveyor belt. In the rear half of each longitudinal fold conveyor belt located between the two tenth rotating shafts, several vertically embedded and through-cut suction holes I are evenly distributed in a matrix. A vacuum generator I is also located on the rear side between the two mounting plates I. The vacuum generator I does not interfere with the transmission movement of the longitudinal fold conveyor belt, and its suction end is positioned upwards, creating a negative pressure through the suction holes I on the rear half of the conveyor belt. The linens on the longitudinal folding conveyor belt are adsorbed and fixed; the front end of the base plate extends to the middle position relative to the tenth rotating shaft, and an adsorption plate is horizontally provided on its upper surface near its front edge. The adsorption plate is positioned at the longitudinal fold crease of the linens, and several adsorption holes II are vertically embedded and opened in a matrix evenly spaced pattern on the upper surface of the adsorption plate. A vacuum generator II is also provided between the two mounting plates I, relative to the adsorption plate position. The vacuum generator II does not interfere with the transmission action of the longitudinal folding conveyor belt, and its adsorption end is set upward, forming a negative pressure to adsorb and fix the linens at the longitudinal fold crease position through the adsorption holes II. The flip plate is horizontally positioned directly above the front half between the two tenth rotating shafts, and its rear end is vertically hinged to the front end of the base plate via a hinge, without interfering with the adsorption plate. The upper surface of the flip plate is located below the horizontal plane of the upper surface of the longitudinal folding conveyor belt, and a clearance groove I is vertically embedded and penetrated on its upper surface relative to the corresponding position of the longitudinal folding conveyor belt. The clearance groove I is a long strip that matches the longitudinal folding conveyor belt, and the clearance groove I ensures that the flip plate does not interfere with the transmission action of the longitudinal folding conveyor belt when it is in a horizontal state. A support plate is horizontally positioned in the middle between the two side plates, and a second cylinder is vertically positioned in the middle of the upper surface of the support plate. The tail of the second cylinder is vertically hinged to the upper surface of the support plate, and its telescopic end is inclined upward and vertically hinged to the lower surface of the flip plate, without interfering with the transmission action of the longitudinal folding conveyor belt. Then, driven by the second cylinder, the flip plate flips upward and backward, folding the linen longitudinally.

[0012] Preferably, the stacking conveyor mechanism includes a movable seat, vertical plates, mounting plate II, an eleventh rotating shaft, a stacking conveyor belt I, a twelfth rotating shaft, a stacking conveyor belt II, a third cylinder, a connector, a pressure plate, a handle, a slide, a pulley block I, a buffer assembly, a roller block, a pulley block II, and a fourth adjusting roller; a hollow rectangular movable seat is horizontally arranged on the upper surface of the base relative to the right side of the longitudinal folding conveyor mechanism and located inside the housing, and the upper and lower surfaces of the movable seat are open. Vertical plates are symmetrically arranged at intervals on the left side of the front and rear surfaces of the movable seat, with the upper ends of the two vertical plates extending vertically upwards beyond the upper surface of the movable seat and reaching the horizontal plane where the upper surface of the longitudinal folding conveyor belt is located; the mounting plate II is horizontally arranged, and its front and rear surfaces are rotatably connected to the two vertical plates respectively on the left side. The right end of the mounting plate II is inclined to the lower right direction, and in the... The front and rear surfaces of the movable seat are vertically equipped with third cylinders relative to the right end of the mounting plate II. The tail of each third cylinder is vertically and laterally hinged to the front and rear surfaces of the movable seat, and its telescopic end is inclined to the upper right. It is also hinged to the right end of the front and rear surfaces of the mounting plate II through connecting parts. Driven by the third cylinder, the mounting plate II rotates vertically and laterally around the two vertical plates. Eleventh rotating shafts are also horizontally and longitudinally mounted at the left and right ends of the mounting plate II. Each eleventh rotating shaft rotates synchronously with the mounting plate II and does not interfere with the rotation of the mounting plate II. Several stacking conveyor belts I are also arranged in a ring at intervals along the longitudinal direction on the two eleventh rotating shafts. The folded linens are transported to the right by the clockwise rotation of the stacking conveyor belts I, and the upper surface of the left end of the stacking conveyor belt I is horizontally and coplanarly arranged with the upper surface of the longitudinal folding conveyor belt. A pressure plate is horizontally provided between the mounting plate II and the movable seat. The pressure plate is spaced apart directly above the movable seat, and its front and rear surfaces, near the right end, are fixedly connected to the corresponding connecting parts, thus moving up and down with the rotation of the mounting plate II. Several horizontally arranged twelfth rotating shafts are sequentially aligned from left to right on the upper surface of the movable seat, and the two ends of each twelfth rotating shaft are rotatably connected to corresponding positions on the front and rear inner surfaces of the movable seat. Several stacking conveyor belts II are also sequentially and annularly sleeved along all the twelfth rotating shafts. The folded linens are stacked and transported to the left under the pressure plate by the counterclockwise rotation of the stacking conveyor belt II. Then, the stacked and flattened linens are transported to the right by the clockwise rotation of the stacking conveyor belt II. A fourth adjusting roller is also horizontally and longitudinally provided on the upper surface of the lower half of the stacking conveyor belt II located between two adjacent twelfth rotating shafts. After the position of the fourth adjusting roller is adjusted, its two ends are screwed and fixed to the corresponding positions of the front and rear inner surfaces of the moving seat, ensuring that its roller surface can rotate around its own axis. The tension of the stacking conveyor belt II is then adjusted by the fourth adjusting roller. A horizontal sliding groove is provided on the upper surface of the base relative to the front and rear edges of the lower surface of the movable seat. A pulley group I matching the sliding groove is also provided on the left side of the front and rear edges of the lower surface of the movable seat. Through the cooperation of pulley group I and the sliding groove, the movable seat and the base are horizontally slidably connected. A pulley group II is also provided on the upper surface of the base relative to the right end of each sliding groove. The sliding contact between pulley group II and the corresponding position on the lower surface of the movable seat ensures the stability of the horizontal sliding of the movable seat. The right end of the movable seat extends out of the vertical plane containing the right side of the base. Roller groups are also provided at intervals on the right side of its lower surface. The rolling end of each roller group contacts the ground downwards, and its rolling direction is consistent with the sliding direction of the movable seat. A handle is also provided on the right side of the movable seat, allowing the movable seat to move horizontally by pulling the handle.

[0013] Preferably, a locking frame is provided at the middle position of the right inner side of the movable seat, and a locking component matching the locking frame is provided on the upper surface of the base relative to the locking frame. The movable seat is locked and fixed by the cooperation of the locking component and the locking frame, ensuring that the stacking conveyor mechanism is set close to the longitudinal folding conveyor mechanism. The locking component includes a housing, hook locking plates, a first connecting shaft, a connecting plate, a pedal, a second connecting shaft, tension spring I, a limit shaft I, a tension spring II, and a limit shaft II. A housing is provided on the upper surface of the base relative to the locking frame, and the right side of the housing is open. Hook locking plates matching the locking frame are symmetrically arranged horizontally at intervals in the upper part of the housing. The middle section between the two hook locking plates is vertically and laterally rotatably connected to the housing by a first connecting shaft arranged horizontally in the longitudinal direction, and its locking end extends horizontally to the right out of the housing and is connected to the locking frame. The lower surface of the locking frame is snapped and locked; inside the housing, an L-shaped connecting plate is provided below each hook locking plate.

A pedal is provided horizontally and horizontally between the lower ends of the folded sections of the horizontal edges of the two connecting plates. The pedal extends horizontally to the right from the right side of the moving seat. By applying a downward force to the pedal, the connecting plate rotates clockwise around the second connecting shaft, thereby causing the hook locking plate to rotate clockwise around the first connecting shaft and disengage from the locking frame. Inside the housing, a horizontally longitudinally positioned limiting shaft II is located at the midpoint of the lower surface of the hook-lock plate. Both ends of the limiting shaft II are connected to corresponding positions on the front and rear inner surfaces of the housing, and the counter-clockwise rotation of the hook-lock plate is limited by the limiting shaft II. An inclined tension spring II is also provided between the limiting shaft II and the upper ends of the horizontal flanges of the two connecting plates, and the tension spring II returns the connecting plates to a horizontal position. Inside the housing, a horizontally longitudinally positioned limiting shaft I is located on the left side of the lower surface of the connecting plate, with both ends connected to corresponding positions on the front and rear inner surfaces of the housing. The limiting shaft I limits the counter-clockwise rotation of the connecting plates. A vertical tension spring I is also provided between the limiting shaft I and the left side of the lower surfaces of the two hook-lock plates, and the tension spring I returns the hook-lock plates to a horizontal position.

[0014] The innovative aspect of this invention, which describes a method for using a multifunctional small-item linen folding machine structure, lies in the inclusion of the following steps: (1) When double horizontal folds are required (1.1) Firstly, driven by the first cylinder, the first rotating shaft rotates vertically and horizontally around the first hinge seat with the adjusting rod to adapt to the feeding machine of different heights; (1.2) Then the feeder sends the linen to the upper conveyor belt and transmits it to the upper right direction via the upper conveyor belt. When the position of the first lateral fold of the linen is detected to reach the air jet hole I, the first air jet component sprays gas and blows the linen located at the third rotating shaft to fold it laterally once. At this time, the linen after the first lateral fold is transmitted to the lower left direction via the middle conveyor mechanism. During this process, the linen transmitted by the middle conveyor belt is flattened by the upper conveyor belt located between the third and fourth rotating shafts. (1.3) When the second horizontal fold crease of the linen after the first horizontal fold is detected to reach the air jet hole II, the second air jet assembly sprays gas and blows the linen located at the fifth pivot to perform a second horizontal fold. At this time, the linen after the second horizontal fold is horizontally transported to the right by the lower conveyor belt, thereby realizing the double horizontal folding operation. (1.4) Then the linen after being folded twice laterally is transferred to the longitudinal folding conveyor belt. At this time, the second cylinder does not work, and the folded linen is directly transferred to the right to the stacking conveyor belt I by the clockwise rotation of the longitudinal folding conveyor belt. (1.5) The folded linens are transported to the right by the clockwise rotation of the stacking conveyor belt I and stacked on the stacking conveyor belt II. Then, the stacked linens are transported horizontally to the left by the counterclockwise rotation of the stacking conveyor belt II to be flattened directly under the pressure plate. At this time, the telescopic end of the third cylinder retracts, driving the pressure plate to move downward and flatten the stacked linens. (1.6) Then, the stacked and flattened linens are transported to the right by the clockwise rotation of the stacking conveyor belt II; (2) When a cross fold is required (2.1) First, driven by the first cylinder, the first rotating shaft rotates vertically and horizontally around the first hinge seat with the adjusting rod to adapt to the feeding machine of different heights; (2.2) Then the feeder sends the linen to the upper conveyor belt and transmits it to the upper right direction via the upper conveyor belt. When the position of the first lateral fold of the linen is detected to reach the air jet hole I, the first air jet component sprays gas and blows the linen located at the third rotating shaft to fold it laterally once. At this time, the linen after the first lateral fold is transmitted to the lower left direction via the middle conveyor mechanism. During this process, the linen transmitted by the middle conveyor belt is flattened by the upper conveyor belt located between the third and fourth rotating shafts. (2.3) When the first end of the linen after a horizontal fold is detected to reach the jet hole II, the second jet assembly sprays gas and blows the first end of the linen located at the fifth pivot onto the lower conveyor belt for horizontal rightward transport. (2.4) After the linen is folded horizontally once, it is transferred to the longitudinal folding conveyor belt and placed in place. The longitudinal folding conveyor belt stops working. At this time, vacuum generator I works to form negative pressure and adsorbs and fixes the linen located on the rear half of the longitudinal folding conveyor belt through adsorption hole I. At the same time, vacuum generator II works to form negative pressure and adsorbs and fixes the longitudinal fold crease of the linen through adsorption hole II. (2.5) The telescopic end of the second cylinder extends, driving the flap to flip upward and backward, folding the linen longitudinally, thus achieving cross folding; after the longitudinal folding is completed, the telescopic end of the second cylinder retracts until the flap is in a horizontal state, and then the longitudinal folding conveyor belt starts again, and the folded linen is transferred to the right to the stacking conveyor belt I by the clockwise rotation of the longitudinal folding conveyor belt. (2.6) The folded linens are transported to the right by the clockwise rotation of the stacking conveyor belt I and stacked on the stacking conveyor belt II. Then, the stacked linens are transported horizontally to the left by the counterclockwise rotation of the stacking conveyor belt II to be flattened directly under the pressure plate. At this time, the telescopic end of the third cylinder retracts, driving the pressure plate to move downward and flatten the stacked linens. (2.7) Then, the stacked and flattened linens are transported to the right by the clockwise rotation of the stacking conveyor belt II; (3) When maintenance is required, the upper conveying mechanism, the first jet assembly, the middle conveying mechanism, the second jet assembly, the lower conveying mechanism, the longitudinal folding conveying mechanism, and the stacking conveying mechanism shall all stop working; Then, by applying a downward force to the pedal, the connecting plate rotates clockwise around the second connecting shaft, which in turn causes the hook lock plate to rotate clockwise around the first connecting shaft and disengage from the lock frame. At this point, through the cooperation of pulley block I, slide groove, pulley block II, and roller block, the stacking conveyor mechanism and the longitudinal folding conveyor mechanism can be separated, thereby providing maintenance space.

[0015] The beneficial effects of this invention are: (1) The present invention has a compact structure and is easy to maintain. It realizes the integrated design of double horizontal fold and cross fold functions, and the two folding methods can share the same output channel, which greatly reduces the difficulty of manual collection and the difficulty of subsequent automation upgrade, and saves the floor space and equipment cost. (2) The present invention only requires setting the blowing time node of the second jet component in the program, without making any adjustments to the structure and the conveying path of the linen, so as to realize the switching between double horizontal fold and cross fold functions. This process saves time and effort and improves work efficiency. (3) The present invention uses stacking conveyor belt I, stacking conveyor belt II, third cylinder and pressure plate to flatten each layer of linen stacking, so that the linen stacking is as compact as possible and avoids looseness, thereby ensuring the accuracy and neatness of the next layer of linen stacking. (4) By using the locking components, chute, pulley group I, buffer components, lock frame, roller group and pulley group II in combination, the present invention can quickly separate the stacking conveyor and the longitudinal folding conveyor, thereby exposing the key maintenance points of the equipment and providing maintenance space to facilitate personnel to carry out inspection and maintenance.

Detailed Implementation

[0026] The technical solution of the present invention will be clearly and completely described below through specific embodiments.

[0027] The present invention discloses a multifunctional small-item linen folding machine structure, comprising a base 1, a housing 2, an upper conveying mechanism 3, a first air jet assembly 4, a middle conveying mechanism 5, a second air jet assembly 6, a lower conveying mechanism 7, a longitudinal folding conveying mechanism 8, and a stacking conveying mechanism 9; wherein, the base 1 and the housing 2 serve as mounting carriers for each mechanism; the specific structure is as follows. Figures 1-8As shown, a shell 2 with an open lower surface is integrally formed on the left side of the upper surface of the horizontally arranged base 1. Inside the shell 2, an upper conveying mechanism 3, a middle conveying mechanism 5, and a lower conveying mechanism 7 are arranged sequentially from top to bottom. The upper conveying mechanism 3 and the middle conveying mechanism 5 are both inclined to the upper right. A first air jet assembly 4 is provided on the right side between their right ends. The first air jet assembly 4 blows air to fold the linen 15, which is being transported to the upper right by the upper conveying mechanism 3, in a horizontal direction, and then transports it to the lower left by the middle conveying mechanism 5. The lower conveying mechanism 7 is horizontally arranged. Inside the shell 2, a longitudinal folding conveying mechanism 8 and a stacking conveying mechanism 9 are arranged sequentially from left to right relative to the right side of the lower conveying mechanism 7. A second air jet assembly 6 is provided on the left side between the left ends of the middle conveying mechanism 5 and the lower conveying mechanism 7. By selecting the blowing time node of the second air jet assembly 6 and cooperating with the longitudinal folding conveying mechanism 8, the double horizontal folding and cross folding functions can be switched. The stacking conveying mechanism 9 then stacks and flattens the folded linen 15.

[0028] The upper conveying mechanism 3 of the present invention includes a first hinge seat 301, an adjusting rod 302, a first rotating shaft 303, a second hinge seat 304, a first cylinder 305, a second rotating shaft 306, a third rotating shaft 307, a fourth rotating shaft 308, a first adjusting roller 309, and an upper conveyor belt 310; as shown Figure 1 , Figure 2 As shown, on the left side of the housing 2, symmetrically spaced at intervals relative to the lower conveying mechanism 7, there are vertically and horizontally arranged fixing plates 10. On the left side of the housing 2, symmetrically spaced at intervals above the fixing plates 10, there are also vertically and horizontally arranged first hinge seats 301. On the left side of the housing 2, symmetrically spaced at intervals below the fixing plates 10, there are also vertically and horizontally arranged second hinge seats 304. On the left side of each first hinge seat 301, there is a horizontally arranged adjusting rod 302. The right end of each adjusting rod 302 extends obliquely upwards and to the right, and is vertically and horizontally rotatably connected to the corresponding first hinge seat 301. A first rotating shaft 303 is horizontally and longitudinally rotatably provided between the left ends of the two adjusting rods 302, and a first cylinder 305 is vertically provided between each second hinge seat 304 and the corresponding adjusting rod 302. The tail of each first cylinder 305 is vertically and laterally rotatably connected to the corresponding second hinge seat 304, and its extension end is inclined to the upper left direction and vertically and laterally rotatably connected to the corresponding position on the lower surface of the corresponding adjusting rod 302. Thus, under the drive of the first cylinder 305, the first rotating shaft 303 rotates vertically around the housing 2 with the adjusting rod 302 so as to adapt to the different heights of the feeder in the front row by adjusting the angle. like Figure 1 , Figure 2As shown, inside the housing 2, at the upper right position, a second rotating shaft 306 and a third rotating shaft 307 are arranged horizontally and longitudinally, spaced apart on the same plane. The lower end of the second rotating shaft 306 is located above the upper end of the first rotating shaft 303. The lengths of the second rotating shaft 306 and the third rotating shaft 307 are matched with the length of the first rotating shaft 303. The two ends of the second rotating shaft 306 and the third rotating shaft 307 are respectively rotatably connected to the front and rear inner surfaces of the housing 2 around their own axial direction. Between the two fixed plates 10, at the upper position, a fourth rotating shaft 308 is also arranged horizontally and longitudinally, matching the length of the first rotating shaft 303. Several upper conveyor belts 310 are arranged longitudinally and spaced apart, and each upper conveyor belt 310 is respectively ring-fitted to the first rotating shaft 303 and the second rotating shaft 307. The upper conveyor belt 310, located on shaft 306, third shaft 307, and fourth shaft 308, transports the linens 15 fed out by the feeder to the upper right direction via clockwise rotation. A first adjusting roller 309 is also horizontally and longitudinally arranged on the left side of the upper conveyor belt 310 located between the first shaft 303 and the fourth shaft 308, and the length of the roller surface of the first adjusting roller 309 matches the length of the first shaft 303. After the position of the first adjusting roller 309 is adjusted, its two ends are screwed to the left side of the front and rear inner surfaces of the housing 2, respectively, ensuring that the roller surface of the first adjusting roller 309 can rotate around its own axis. Thus, the tension of the upper conveyor belt 310 is adjusted by the first adjusting roller 309, and the housing 2 does not interfere with the movement of the upper conveyor belt 310 in transporting the linens 15. The power source for driving the upper conveyor belt 310 to rotate clockwise in this invention can be an electric motor, which is existing technology. Therefore, the principle of how to drive the upper conveyor belt 310 to rotate clockwise will not be described in detail here.

[0029] The intermediate conveying mechanism 5 of this invention includes a fifth rotating shaft 51, a sixth rotating shaft 52, a seventh rotating shaft 53, a guide roller 54, a second adjusting roller 55, a third adjusting roller 56, and an intermediate conveyor belt 57; as shown... Figure 1 , Figure 2As shown, inside the housing 2, a fifth rotating shaft 51 is horizontally and longitudinally rotatable relative to the fourth rotating shaft 308. Inside the housing 2, a seventh rotating shaft 53, matching the length of the fifth rotating shaft 51, is horizontally and longitudinally rotatable relative to the lower left of the third rotating shaft 307. The seventh rotating shaft 53 is positioned near the third rotating shaft 307, and its lower end is located above the upper end of the fifth rotating shaft 51. Several intermediate conveyor belts 57 are arranged longitudinally at intervals, and each intermediate conveyor belt 57 is looped around the fifth rotating shaft 51 and the seventh rotating shaft 53. The counter-clockwise rotation of the intermediate conveyor belts 57 transports the linen 15, after a horizontal fold, towards the lower left. The upper conveyor belt 310, located between the third rotating shaft 307 and the fourth rotating shaft 308, flattens the linen 15 transported by the intermediate conveyor belts 57. The lower half of the lower surface of section 7 is provided with a sixth rotating shaft 52 and a third adjusting roller 56 arranged horizontally and longitudinally at intervals on the left and right near the position of the seventh rotating shaft 53. The sixth rotating shaft 52 is located at the lower right of the line connecting the center of the fifth rotating shaft 51 and the center of the seventh rotating shaft 53, and the third adjusting roller 56 is located at the upper right of the sixth rotating shaft 52. The length of the sixth rotating shaft 52 matches the length of the fifth rotating shaft 51, and its two ends are rotatably connected to the corresponding positions of the front and rear inner surfaces of the housing 2. The length of the roller surface of the third adjusting roller 56 matches the length of the fifth rotating shaft 51. After the position of the third adjusting roller 56 is adjusted, its two ends are screwed and fixed to the corresponding positions of the front and rear inner surfaces of the housing 2, and its roller surface can rotate around its own axis. Thus, the tension of the middle conveyor belt 57 is adjusted by the third adjusting roller 56, and the housing 2 does not interfere with the movement of the middle conveyor belt 57 to transport the linen 15. like Figure 1 , Figure 2As shown, a second adjusting roller 55 is horizontally and longitudinally arranged on the upper surface of the middle conveyor belt 57 located between the sixth rotating shaft 52 and the third adjusting roller 56. The two ends of the second adjusting roller 55 are rotatably connected to the corresponding positions of the front and rear inner surfaces of the housing 2. The tension of the middle conveyor belt 57 is adjusted by adjusting the position of the third adjusting roller 56 and by assisting the second adjusting roller 55. A guide roller 54 is horizontally and longitudinally arranged on the upper surface of the middle conveyor belt 57 located between the fifth rotating shaft 51 and the sixth rotating shaft 52 near the position of the fifth rotating shaft 51. The two ends of the guide roller 54 are rotatably connected to the corresponding positions of the front and rear inner surfaces of the housing 2. The lower end of the guide roller 54 is located at the position of the lower end of the fifth rotating shaft 51. The guide roller 54 guides the middle conveyor belt 57 located between the fifth rotating shaft 51 and the sixth rotating shaft 52. In this way, the guide roller 54 ensures that other structures installed inside the housing 2 do not interfere with the transmission action of the middle conveyor belt 57. The power source for driving the middle conveyor belt 57 to rotate counterclockwise in this invention can be an electric motor, which is existing technology. Therefore, the principle of how to drive the middle conveyor belt 57 to rotate counterclockwise will not be described in detail here.

[0030] The lower conveying mechanism 7 of the present invention includes an eighth rotating shaft 71, a ninth rotating shaft 72, and a lower conveyor belt 73; as shown Figure 1 , Figure 2 As shown, inside the housing 2, a horizontally rotatable eighth shaft 71 is provided relative to the fifth shaft 51 directly below it. The vertical longitudinal plane containing the left end of the eighth shaft 71 is located to the right of the vertical longitudinal plane containing the left end of the fifth shaft 51. Inside the housing 2, a horizontally rotatable ninth shaft 72, matching the length of the eighth shaft 71, is also provided relative to the right of the eighth shaft 71. The upper end faces of the eighth shaft 71 and the ninth shaft 72 are horizontally coplanar. Several lower conveyor belts 73 are arranged longitudinally at intervals and are respectively ring-fitted around the eighth shaft 71 and the ninth shaft 72. On the ninth rotating shaft 72, the linen 15 is then horizontally transported to the right to the longitudinal folding conveyor mechanism 8 via the clockwise rotation of the lower conveyor belt 73. The distance between the middle conveyor belt 57, located between the fifth rotating shaft 51 and the guide roller 54, and the lower conveyor belt 73 must ensure that the second air jet assembly 6 can blow the first end of the linen 15 after one transverse fold onto the lower conveyor belt 73 for horizontal rightward transport. Simultaneously, it must ensure that the second air jet assembly 6 can perform a second transverse fold on the linen 15 after one transverse fold and blow it onto the lower conveyor belt 73 for horizontal rightward transport. The power source driving the clockwise rotation of the lower conveyor belt 73 in this invention can be an electric motor, which is existing technology; therefore, the principle of how to drive the clockwise rotation of the lower conveyor belt 73 will not be described in detail here.

[0031] In this invention, the upper conveyor belt 310 located between the third rotating shaft 307 and the fourth rotating shaft 308, and the middle conveyor belt 57 located between the fifth rotating shaft 51 and the seventh rotating shaft 53 are arranged parallel to each other vertically. The distance between the upper conveyor belt 310 and the middle conveyor belt 57 must ensure that the linens 15 transported by the middle conveyor belt 57 can be flattened by the upper conveyor belt 310, and that the upper conveyor belt 310 does not interfere with the transport action of the middle conveyor belt 57. Figure 1 , Figure 2 As shown, the first jet assembly 4 is located inside the housing 2 on the right side relative to the third rotating shaft 307 and the seventh rotating shaft 53, and has several jet holes I spaced longitudinally at its jet end, ensuring that each jet hole I is positioned to the left towards the area between the third rotating shaft 307 and the seventh rotating shaft 53; the spraying position of each jet hole I corresponds to the position of the first lateral fold crease of the linen 15 located at the third rotating shaft 307, and the spraying action of the first jet assembly 4 folds the linen 15 located at the third rotating shaft 307 into a lateral fold. Simultaneously, the linen 15 after the lateral fold is conveyed to the lower left direction by the middle conveyor mechanism 5, and during this process... The upper conveyor belt 310, located between the third rotating shaft 307 and the fourth rotating shaft 308, flattens the linens 15 conveyed by the middle conveyor belt 57. A first mounting base 11 is also provided on the inner top surface of the housing 2 relative to the third rotating shaft 307. A first guide plate 12 has an arc-shaped structure and is coaxially spaced at a position slightly to the upper right of the outer side of the third rotating shaft 307. One end of the first guide plate 12 is screwed to the lower end of the first mounting base 11, and the other end faces downwards. It does not interfere with the movement of the first air jet assembly 4 and the upper conveyor belt 310, thus limiting the movement of the linens 15 conveyed by the upper conveyor belt 310 to the right. The first air jet assembly 4 of this invention is a conventional air jet device, so its structure will not be described in detail here.

[0032] The second jet assembly 6 of the present invention is positioned between the two fixed plates 10 at a position lower to the left of the fourth rotating shaft 308, and has several jet holes II spaced longitudinally at its jet end, ensuring that each jet hole II is positioned to the right in the area between the fifth rotating shaft 51 and the eighth rotating shaft 71; Figure 1 , Figure 2As shown, the blowing position of each jet nozzle II corresponds to the position of the second transverse fold crease of the linen 15 located at the fifth rotating shaft 51. By selecting the blowing time node of the second jet assembly 6, the linen 15 located at the fifth rotating shaft 51 is either blown onto the lower conveyor belt 73 for horizontal rightward transport, or the linen 15 located at the fifth rotating shaft 51 is folded into a second transverse shape before being blown onto the lower conveyor belt 73 for horizontal rightward transport. Inside the housing 2, between the first adjusting roller 309 and the fifth rotating shaft 51, there is also a... A second mounting base 13 is provided, and an arc-shaped second guide plate 14 is provided between each two adjacent upper conveyor belts 310. Each second guide plate 14 is coaxially spaced at a position on the upper left side of the fifth rotating shaft 51, and one end of each guide plate 14 is screwed to the lower end of the second mounting base 13. The other ends of each guide plate 14 are downwardly positioned, and they do not interfere with the movement of the second air jet assembly 6, the upper conveyor belts 310, and the middle conveyor belt 57. Thus, the second guide plate 14 limits the left movement of the linen 15 conveyed by the middle conveyor belt 57. The second air jet assembly 6 of this invention is a conventional air jet device, so its structure will not be described in detail here.

[0033] The longitudinal folding conveyor mechanism 8 of the present invention includes a side plate 801, a support plate 802, a mounting plate I 803, a tenth rotating shaft 804, a longitudinal folding conveyor belt 805, a second cylinder 806, a flip plate 807, a bottom plate 808, and an adsorption plate 811; as shown Figures 1-8 As shown, on the upper surface of the base 1, opposite to the right of the ninth rotating shaft 72 and located inside the housing 2, there are vertically and horizontally arranged side plates 801 symmetrically spaced back and forth. On the upper surface of each side plate 801, there is also a vertically and horizontally arranged mounting plate I 803, with the two mounting plates I 803 symmetrically arranged back and forth. Between the two mounting plates I 803, there are horizontally and vertically arranged tenth rotating shafts 804 symmetrically spaced left and right. The two tenth rotating shafts 804 are respectively located at the left and right ends near the mounting plates I 803, and their ends are respectively connected to the inner surface of the corresponding mounting plate I 803 around their own axial direction. Rotary connection; several longitudinally folded conveyor belts 805 are respectively arranged in a ring at intervals along the longitudinal direction on the front and rear halves of the two tenth rotating shafts 804, and the upper surface of each longitudinally folded conveyor belt 805 is horizontally coplanar with the upper surface of the lower conveyor belt 73, and the linen 15 is horizontally transported to the right by the clockwise rotation of the longitudinally folded conveyor belts 805; the power source for driving the clockwise rotation of the longitudinally folded conveyor belts 805 in this invention can be an electric motor, which is the prior art, so the principle of how to drive the clockwise rotation of the longitudinally folded conveyor belts 805 will not be described in detail here; like Figures 1-8As shown, the base plate 808 is horizontally positioned directly above the rear half between the two tenth rotating shafts 804, and its lower surface near the rear end is fixedly connected to the upper end face of the rear mounting plate I 803, ensuring that the upper surface of the base plate 808 is below the horizontal plane containing the upper surface of the longitudinal folding conveyor belt 805. A clearance groove II is vertically embedded and penetrated on the upper surface of the base plate 808 relative to each longitudinal folding conveyor belt 805, and each clearance groove II is matched to the longitudinal folding conveyor belt 805. The conveyor belt is elongated and its clearance groove II ensures that the base plate 808 does not interfere with the transmission action of the longitudinal folded conveyor belt 805. Several adsorption holes I 810 are vertically embedded and intersected in a matrix on the surface of each longitudinal folded conveyor belt 805 located in the rear half between the two tenth rotating shafts 804. A vacuum generator I is also located on the rear side between the two mounting plates I 803. The vacuum generator I does not interfere with the transmission action of the longitudinal folded conveyor belt 805, and its adsorption end is positioned upwards to create negative pressure. The linen 15 located on the longitudinal folding conveyor belt 805 in the rear half is adsorbed and fixed through the adsorption holes I 810. The front end of the base plate 808 extends to the middle position relative to the tenth rotating shaft 804, and an adsorption plate 811 is horizontally arranged on its upper surface near its front edge. The position of the adsorption plate 811 is aligned with the longitudinal fold crease of the linen 15. Several adsorption holes II 812 are vertically embedded and opened in a matrix evenly spaced pattern on the upper surface of the adsorption plate 811. A vacuum generator II is also arranged between the two mounting plates I 803 relative to the position of the adsorption plate 811. The vacuum generator II does not interfere with the transmission action of the longitudinal folding conveyor belt 805, and its adsorption end is set upward, forming a negative pressure to adsorb and fix the linen 15 at the longitudinal fold crease position through the adsorption holes II 812. The vacuum generator I and vacuum generator II of this invention are conventional equipment, which only need to generate suction to form a negative pressure. This is prior art, so the structure of vacuum generator I and vacuum generator II will not be described in detail here. like Figures 1-8As shown, the flap 807 is horizontally positioned directly above the front half between the two tenth rotating shafts 804, and its rear end is vertically hinged to the front end of the base plate 808 via a hinge, and is configured to not interfere with the adsorption plate 811. The upper surface of the flap 807 is located below the horizontal plane of the upper surface of the longitudinal folding conveyor belt 805, and a clearance groove I 809 is vertically embedded and penetrated on its upper surface relative to the corresponding position of the longitudinal folding conveyor belt 805. The clearance groove I 809 is a long strip that matches the longitudinal folding conveyor belt 805, and the clearance groove I 809 ensures that the flap 807 is in a horizontal state. The transmission action of the longitudinal folding conveyor belt 805 is not interfered with. A horizontal longitudinal support plate 802 is provided in the middle position between the two side plates 801, and a second cylinder 806 is provided vertically in the middle position of the upper surface of the support plate 802. The tail of the second cylinder 806 is vertically hinged to the upper surface of the support plate 802, and its telescopic end is inclined upward and vertically hinged to the lower surface of the flip plate 807. It does not interfere with the transmission action of the longitudinal folding conveyor belt 805. Then, driven by the second cylinder 806, the flip plate 807 flips upward and backward to fold the linen 15 longitudinally.

[0034] The stacking and conveying mechanism 9 of the present invention includes a movable seat 901, a vertical plate 902, a mounting plate II 903, an eleventh rotating shaft 904, a stacking conveyor belt I 905, a twelfth rotating shaft 906, a stacking conveyor belt II 907, a third cylinder 908, a connecting piece 909, a pressure plate 910, a handle 911, a slide 912, a pulley block I 913, a buffer assembly 914, a roller block 926, a pulley block II 927, and a fourth adjusting roller 928; as shown Figures 1-8As shown, a hollow rectangular movable seat 901 is horizontally arranged on the upper surface of the base 1, relative to the right side of the longitudinal conveyor mechanism 8 and located inside the housing 2. The upper and lower surfaces of the movable seat 901 are open. On the left side of the front and rear surfaces of the movable seat 901, vertical plates 902 are symmetrically arranged at intervals. The upper ends of the two vertical plates 902 extend vertically upward from the upper surface of the movable seat 901 and extend to the horizontal plane where the upper surface of the longitudinal conveyor belt 805 is located. The mounting plate II 903 is horizontally arranged, and its front and rear surfaces are rotatably connected to the two vertical plates 902 respectively. The right end of the mounting plate II 903 is inclined to the lower right. On the front and rear surfaces of the movable seat 901, relative to the right end of the mounting plate II 903, a third cylinder 908 is vertically arranged. The tail of each third cylinder 908 is vertically hinged to the front and rear surfaces of the movable seat 901, and its extension end is inclined to the upper right. It is connected to the mounting plate II 903 by the connecting piece 9. 09 is hinged to the right end of the front and rear surfaces of mounting plate II 903, and then, driven by the third cylinder 908, mounting plate II 903 rotates vertically and horizontally around the two vertical plates 902; eleventh rotating shafts 904 are also provided horizontally and longitudinally at the left and right ends of mounting plate II 903, and each eleventh rotating shaft 904 rotates synchronously with mounting plate II 903, and does not interfere with the rotation of mounting plate II 903; along the longitudinal direction on the two eleventh rotating shafts 904, there are also... Several stacking conveyor belts I905 are arranged in a ring at intervals. The folded linen 15 is transported to the right by the clockwise rotation of the stacking conveyor belts I905, and the upper surface of the left end of the stacking conveyor belts I905 is arranged horizontally and coplanarly with the upper surface of the longitudinal folding conveyor belt 805. The power source for driving the clockwise rotation of the stacking conveyor belts I905 can be an electric motor, which is the prior art. Therefore, the principle of how to drive the stacking conveyor belts I905 to rotate clockwise will not be described in detail here. like Figures 1-8As shown, a pressure plate 910 is horizontally provided between the mounting plate II 903 and the movable seat 901. The pressure plate 910 is spaced out above the movable seat 901, and its front and rear surfaces are fixedly connected to the corresponding connecting parts 909 at their right ends, so that it moves up and down with the rotation of the mounting plate II 903. Several horizontally arranged twelfth rotating shafts 906 are arranged in a series of intervals from left to right on the upper surface of the movable seat 901, and the two ends of each twelfth rotating shaft 906 are rotatably connected to the corresponding positions on the front and rear inner surfaces of the movable seat 901. Several stacking conveyor belts II 907 are also arranged in a ring-like arrangement along the longitudinal direction on all the twelfth rotating shafts 906, and the counterclockwise rotation of the stacking conveyor belts II 907 stacks the folded linens 15 and conveys them to the left. The linens 15 are flattened directly below the pressure plate 910, and then transported to the right by the clockwise rotation of the stacking conveyor belt II 907. A fourth adjusting roller 928 is horizontally and longitudinally mounted on the upper surface of the lower half of the stacking conveyor belt II 907, located between two adjacent twelfth rotating shafts 906. After position adjustment, the two ends of the fourth adjusting roller 928 are screwed and fixed to the corresponding positions of the front and rear inner surfaces of the moving seat 901, ensuring that its roller surface can rotate around its own axis. The tension of the stacking conveyor belt II 907 is then adjusted by the fourth adjusting roller 928. The power source driving the rotation of the stacking conveyor belt II 907 in this invention can be an electric motor, which is existing technology; therefore, the principle of how to drive the rotation of the stacking conveyor belt II 907 will not be elaborated here. like Figures 1-8 As shown, a horizontal sliding groove 912 is provided on the upper surface of the base 1 relative to the front and rear edges of the lower surface of the movable seat 901. A pulley assembly I 913 matching the sliding groove 912 is also provided on the left side of the front and rear edges of the lower surface of the movable seat 901. Through the cooperation of the pulley assembly I 913 and the sliding groove 912, the movable seat 901 and the base 1 are horizontally slidably connected. A pulley assembly II 927 is also provided on the upper surface of the base 1 relative to the right end of each sliding groove 912, and the movable seat 901 is connected to the sliding seat 901 through the pulley assembly II 927. The sliding contact at the corresponding position on the lower surface ensures the stability of the horizontal sliding of the movable seat 901; the right end of the movable seat 901 extends out of the vertical plane where the right side of the base 1 is located, and at the right end of its lower surface, there are roller groups 926 spaced back and forth. The rolling end of each roller group 926 is in contact with the ground downward, and its rolling direction is consistent with the sliding direction of the movable seat 901. A handle 911 is also provided on the right side of the movable seat 901, so that the movable seat 901 can be pulled horizontally by the handle 911.

[0035] The present invention further includes a locking frame 925 located at the middle of the right inner side of the movable seat 901, and a locking component matching the locking frame 925 is provided on the upper surface of the base 1 relative to the locking frame 925. The movable seat 901 is locked and fixed by the cooperation of the locking component and the locking frame 925, ensuring that the stacking conveyor 9 is positioned close to the longitudinal folding conveyor 8. The locking component includes a housing 915, a hook locking plate 916, a first connecting shaft 917, a connecting plate 918, a pedal 919, a second connecting shaft 920, a tension spring I 921, a limiting shaft I 922, a tension spring II 923, and a limiting shaft II 924. Figures 1-8 As shown, a housing 915 is provided on the upper surface of the base 1 relative to the locking frame 925, and the right side of the housing 915 is open; inside the housing 915, at a slightly upper position, there are also symmetrically spaced horizontal hook locking plates 916 that match the locking frame 925.

[0036] A method of using the multifunctional small linen folding machine structure of the present invention, such as... Figures 1-8 As shown, it includes the following steps: (1) When double horizontal folds are required (1.1) Firstly, driven by the first cylinder 305, the first rotating shaft 303 rotates vertically and horizontally around the first hinge seat 301 with the adjusting rod 302 to adapt to the feeding machine of different heights; (1.2) Then the feeder sends the linen 15 to the upper conveyor belt 310 and transmits it to the upper right direction via the upper conveyor belt 310. When the position of the first lateral fold of the linen 15 reaches the air jet hole I, the first air jet assembly 4 sprays gas and blows the linen 15 located at the third rotating shaft 307 to fold it laterally once. At this time, the linen 15 after the first lateral fold is transmitted to the lower left direction via the middle conveyor mechanism 5. During this process, the linen 15 transmitted via the middle conveyor belt 57 is flattened by the upper conveyor belt 310 located between the third rotating shaft 307 and the fourth rotating shaft 308. (1.3) When the second horizontal fold crease of the linen 15 after the first horizontal fold is detected to reach the air jet hole II, the second air jet assembly 6 sprays gas and blows the linen 15 located at the fifth rotating shaft 51 to perform a second horizontal fold. At this time, the linen 15 after the second horizontal fold is horizontally transported to the right by the lower conveyor belt 73, thereby realizing the double horizontal folding operation. (1.4) Then the linen 15 after being folded twice laterally is transferred to the longitudinal folding conveyor belt 805. At this time, the second cylinder 806 does not work, and the folded linen 15 is directly transferred to the right to the stacking conveyor belt I 905 by the clockwise rotation of the longitudinal folding conveyor belt 805. (1.5) The folded linen 15 is transported to the right by the clockwise rotation of the stacking conveyor belt I 905 and stacked on the stacking conveyor belt II 907. Then, the stacked linen 15 is transported horizontally to the left by the counterclockwise rotation of the stacking conveyor belt II 907 to be flattened directly under the pressure plate 910. At this time, the telescopic end of the third cylinder 908 retracts, driving the pressure plate 910 to move downward and flatten the stacked linen 15. (1.6) Then, the stacked linens 15 are transported to the right by the clockwise rotation of the stacking conveyor belt II907.

[0037] (2) When a cross fold is required (2.1) First, driven by the first cylinder 305, the first rotating shaft 303 rotates vertically and horizontally around the first hinge seat 301 with the adjusting rod 302 to adapt to the feeding machine of different heights. (2.2) Then the feeder sends the linen 15 to the upper conveyor belt 310 and transmits it to the upper right direction via the upper conveyor belt 310. When the position of the first lateral fold of the linen 15 reaches the air jet hole I, the first air jet assembly 4 sprays gas and blows the linen 15 located at the third rotating shaft 307 to fold it laterally once. At this time, the linen 15 after the first lateral fold is transmitted to the lower left direction via the middle conveyor mechanism 5. During this process, the linen 15 transmitted via the middle conveyor belt 57 is flattened by the upper conveyor belt 310 located between the third rotating shaft 307 and the fourth rotating shaft 308. (2.3) When the first end of the linen 15 after being folded horizontally once is detected to reach the jet hole II, the second jet assembly 6 sprays gas and blows the first end of the linen 15 located at the fifth rotating shaft 51 onto the lower conveyor belt 73 for horizontal rightward transmission. (2.4) After the linen 15 is folded horizontally once, it is transferred to the longitudinal folding conveyor belt 805 and is in place. The longitudinal folding conveyor belt 805 stops working. At this time, the vacuum generator I works to form a negative pressure and adsorbs and fixes the linen 15 located on the rear half of the longitudinal folding conveyor belt 805 through the adsorption hole I 810. At the same time, the vacuum generator II works to form a negative pressure and adsorbs and fixes the longitudinal fold crease of the linen 15 through the adsorption hole II 812. (2.5) The telescopic end of the second cylinder 806 extends, driving the flip plate 807 to flip upward and backward, folding the linen 15 longitudinally, thus achieving the cross folding operation; after the longitudinal folding is completed, the telescopic end of the second cylinder 806 retracts until the flip plate 807 is in a horizontal state, and then the longitudinal folding conveyor belt 805 starts again, and the folded linen 15 is transferred to the right to the stacking conveyor belt I 905 by the clockwise rotation of the longitudinal folding conveyor belt 805; (2.6) The folded linen 15 is transported to the right by the clockwise rotation of the stacking conveyor belt I 905 and stacked on the stacking conveyor belt II 907. Then, the stacked linen 15 is transported horizontally to the left by the counterclockwise rotation of the stacking conveyor belt II 907 to be flattened directly under the pressure plate 910. At this time, the telescopic end of the third cylinder 908 retracts, driving the pressure plate 910 to move downward and flatten the stacked linen 15. (2.7) Then, the stacked linens 15 are transported to the right by the clockwise rotation of the stacking conveyor belt II907.

[0038] (3) When maintenance is required, the upper conveying mechanism 3, the first jet assembly 4, the middle conveying mechanism 5, the second jet assembly 6, the lower conveying mechanism 7, the longitudinal folding conveying mechanism 8, and the stacking conveying mechanism 9 shall all stop working; Then, by applying a downward force to the pedal 919, the connecting plate 918 rotates clockwise around the second connecting shaft 920, thereby causing the hook locking plate 916 to rotate clockwise around the first connecting shaft 917 and disengage from the locking frame 925; at this time, through the cooperation of pulley block I 913, slide 912, pulley block II 927 and roller block 926, the stacking conveyor 9 can be separated from the longitudinal folding conveyor 8, thereby providing maintenance space.

[0039] The beneficial effects of this invention are: (1) The present invention has a compact structure and is easy to maintain. It realizes the integrated design of double horizontal fold and cross fold functions, and the two folding methods can share the same output channel, which greatly reduces the difficulty of manual collection and the difficulty of subsequent automation upgrade, and saves the floor space and equipment cost. (2) The present invention only requires setting the blowing time node of the second jet component 6 in the program, without making any adjustments to the structure and the conveying path of the linen 15, so as to realize the switching between double horizontal fold and cross fold functions. This process saves time and effort and improves work efficiency. (3) By using the stacking conveyor belt I 905, the stacking conveyor belt II 907, the third cylinder 908 and the pressure plate 910 together, the present invention can flatten each layer of linen 15 stacks, making the linen 15 stacks as compact as possible and avoiding looseness, thereby ensuring the accuracy and neatness of the next layer of linen 15 stacks. (4) By using the locking component, slide 912, pulley group I 913, buffer component 914, lock frame 925, roller group 926 and pulley group II 927 together, the present invention can quickly separate the stacking conveyor 9 from the longitudinal folding conveyor 8, thereby exposing the key maintenance points of the equipment and providing maintenance space to facilitate personnel to carry out inspection and maintenance.

A vertical tension spring I is also provided between the limiting shaft I and the left side of the lower surfaces of the two hook-lock plates, and the tension spring I returns the hook-lock plates to a horizontal position.

10. The method of using the multifunctional small-item linen folding machine structure according to claim 9, characterized in that... Includes the following steps: (1) When double horizontal folds are required (1.1) Firstly, driven by the first cylinder, the first rotating shaft rotates vertically and horizontally around the first hinge seat with the adjusting rod to adapt to the feeding machine of different heights; (1.2) Then the feeder sends the linen to the upper conveyor belt and transmits it to the upper right direction via the upper conveyor belt. When the position of the first lateral fold of the linen is detected to reach the air jet hole I, the first air jet component sprays gas and blows the linen located at the third rotating shaft to fold it laterally once. At this time, the linen after the first lateral fold is transmitted to the lower left direction via the middle conveyor mechanism. During this process, the linen transmitted by the middle conveyor belt is flattened by the upper conveyor belt located between the third and fourth rotating shafts. (1.3) When the second horizontal fold crease of the linen after the first horizontal fold is detected to reach the air jet hole II, the second air jet assembly sprays gas and blows the linen located at the fifth pivot to perform a second horizontal fold. At this time, the linen after the second horizontal fold is horizontally transported to the right by the lower conveyor belt, thereby realizing the double horizontal folding operation. (1.4) Then the linen after being folded twice laterally is transferred to the longitudinal folding conveyor belt. At this time, the second cylinder does not work, and the folded linen is directly transferred to the right to the stacking conveyor belt I by the clockwise rotation of the longitudinal folding conveyor belt. (1.5) The folded linens are transported to the right by the clockwise rotation of the stacking conveyor belt I and stacked on the stacking conveyor belt II. Then, the stacked linens are transported horizontally to the left by the counterclockwise rotation of the stacking conveyor belt II to be flattened directly under the pressure plate. At this time, the telescopic end of the third cylinder retracts, driving the pressure plate to move downward and flatten the stacked linens. (1.6) Then, the stacked and flattened linens are transported to the right by the clockwise rotation of the stacking conveyor belt II; (2) When a cross fold is required (2.1) First, driven by the first cylinder, the first rotating shaft rotates vertically and horizontally around the first hinge seat with the adjusting rod to adapt to the feeding machine of different heights; (2.2) Then the feeder sends the linen to the upper conveyor belt and transmits it to the upper right direction via the upper conveyor belt. When the position of the first lateral fold of the linen is detected to reach the air jet hole I, the first air jet component sprays gas and blows the linen located at the third rotating shaft to fold it laterally once. At this time, the linen after the first lateral fold is transmitted to the lower left direction via the middle conveyor mechanism. During this process, the linen transmitted by the middle conveyor belt is flattened by the upper conveyor belt located between the third and fourth rotating shafts. (2.3) When the first end of the linen after a horizontal fold is detected to reach the jet hole II, the second jet assembly sprays gas and blows the first end of the linen located at the fifth pivot onto the lower conveyor belt for horizontal rightward transport. (2.4) After the linen is folded horizontally once, it is transferred to the longitudinal folding conveyor belt and placed in place. The longitudinal folding conveyor belt stops working. At this time, vacuum generator I works to form negative pressure and adsorbs and fixes the linen located on the rear half of the longitudinal folding conveyor belt through adsorption hole I. At the same time, vacuum generator II works to form negative pressure and adsorbs and fixes the longitudinal fold crease of the linen through adsorption hole II. (2.5) The telescopic end of the second cylinder extends, driving the flap to flip upward and backward, folding the linen longitudinally, thus achieving cross folding; after the longitudinal folding is completed, the telescopic end of the second cylinder retracts until the flap is in a horizontal state, and then the longitudinal folding conveyor belt starts again, and the folded linen is transferred to the right to the stacking conveyor belt I by the clockwise rotation of the longitudinal folding conveyor belt. (2.6) The folded linens are transported to the right by the clockwise rotation of the stacking conveyor belt I and stacked on the stacking conveyor belt II. Then, the stacked linens are transported horizontally to the left by the counterclockwise rotation of the stacking conveyor belt II to be flattened directly under the pressure plate. At this time, the telescopic end of the third cylinder retracts, driving the pressure plate to move downward and flatten the stacked linens. (2.7) Then, the stacked and flattened linens are transported to the right by the clockwise rotation of the stacking conveyor belt II; (3) When maintenance is required, the upper conveying mechanism, the first jet assembly, the middle conveying mechanism, the second jet assembly, the lower conveying mechanism, the longitudinal folding conveying mechanism, and the stacking conveying mechanism shall all stop working; Then, by applying a downward force to the pedal, the connecting plate rotates clockwise around the second connecting shaft, which in turn causes the hook lock plate to rotate clockwise around the first connecting shaft and disengage from the lock frame. At this point, through the cooperation of pulley block I, slide groove, pulley block II, and roller block, the stacking conveyor mechanism and the longitudinal folding conveyor mechanism can be separated, thereby providing maintenance space.
