Description

Technical Field

[0001] The present application relates to the field of cotton towel manufacturing, and in particular to a conveying and sorting device of a cotton towel folding device. Background Art

[0002] Cotton soft towel is a non-woven fabric sanitary cleaning product. In the manufacturing process of cotton soft towel, the cloth roll made by non-woven processes such as spunlace needs to be released, and then cut into long cloth strips with a width of about 200mm, and then the long cloth strips are folded in width into a U shape, and two adjacent long cloth strips are cross-overlapped, that is, one side of the U-shaped long cloth strip is inserted into the U-shaped interior of the adjacent long cloth strip, so that several folded long cloth strips are stacked, and then the long cloth strips are transmitted to the subsequent cutting equipment via a conveyor belt for cutting in the length direction. Reference can be made to a paper cutting device with stable cutting size with announcement number CN221936882U.

[0003] Regarding the above-mentioned related technologies, after a predetermined number of long cloth strips are stacked, the top long cloth strip is in a relatively fluffy state due to its limited weight, especially the top long cloth strip is prone to uneven areas on the upper surface. Please refer to the attached manual for details. Figure 5 , which makes the unfolded pattern of the cotton towel product obtained when the overlapped long cloth strips are subsequently cut easily to present an irregular pattern, and the unfolded size of the cotton towel product is prone to deviation, and the quality of the cotton towel product is prone to be unqualified. Summary of the invention

[0004] In order to reduce the possibility of unqualified cotton towel products, the present application provides a conveying and sorting device for a cotton towel folding device.

[0005] The conveying and sorting device of a cotton towel folding device provided in the present application adopts the following technical solution.

[0006] A conveying and sorting device for a cotton towel folding device includes a conveyor for transporting long cloth strips that have been folded from a folding body, the frame of the conveyor is detachably connected to a downward pressure cylinder, and the power rod of the downward pressure cylinder is detachably connected to a downward pressure piece that can be tightly pressed on the upper part of the folded long cloth strips.

[0007] By adopting the above technical solution, after several long cloth strips are overlapped, they are moved via a conveyor to directly below the lower pressing piece, and then the lower pressing piece moves downward to press the upper part of the overlapped long cloth strips, so that the upper part of the originally fluffy overlapped long cloth strips is tightened, and the surface of the topmost long cloth strip is made as flat as possible, so as to reduce the possibility of certain differences in the unfolded shape of the cotton towel product after cutting, which helps to improve the quality of the cotton towel product.

[0008] Optionally, when the pressing member is pressed tightly against the overlapping long cloth strips, the projection of the pressing member on the conveyor belt partially overlaps with the overlapping long cloth strips, and there is a gap between the projection of the pressing member on the conveyor belt and the U-shaped bend of the topmost long cloth strip.

[0009] By adopting the above technical solution, when the top long cloth strip is overlapped, one side of its U-shaped bend will be offset toward the side of its own U-shaped opening, and the offset amount at each location is different. For this reason, the pressing piece is designed so that the side will not be tightly pressed against the U-shaped bend side of the top long cloth strip, so that the U-shaped bend side of the top long cloth strip can be aligned with the U-shaped bend side of other long cloth strips in the same vertical direction during the process of the pressing piece contacting the overlapped long cloth strips, which helps to improve the quality of cotton soft towel products.

[0010] Optionally, the pressing member can press the surface of the stacked long cloth strips to be in an arc shape, and the center height of the arc surface of the pressing member is higher than the arc surface height of the pressing member.

[0011] By adopting the above technical solution, the lower pressing piece is first pressed on the middle position in the width direction of the long cloth strip, so that the U-shaped bent side of the top long cloth strip can be effectively aligned with the U-shaped bent side of other long cloth strips in the same vertical direction during the process of the lower pressing piece contacting the overlapping long cloth strips.

[0012] Optionally, the frame of the conveyor is detachably connected with a shift cylinder, and the shift cylinder power rod is detachably connected with a shift piece, which is closer to the transmission end of the conveyor than the pressing piece, and can be close to the U-shaped bend side of the top long cloth strip.

[0013] By adopting the above technical solution, it is not easy for the stop position of the overlapped long cloth strips to have a large deviation each time, so that the pressing member can abut against the predetermined position on the upper surface of the overlapped long cloth strips.

[0014] Optionally, the frame of the conveyor is detachably connected with a photoelectric sensor that can face the long folded cloth strips being transported, and the photoelectric sensor and the gear cylinder are electrically connected to an external controller.

[0015] By adopting the above technical solution, after the folded long cloth strip passes the predetermined position, the stopper can move downward, so that the stopper can timely and effectively stop the moving folded long cloth strip at the predetermined position.

[0016] Optionally, the conveyor includes a transverse conveyor and a longitudinal conveyor. The longitudinal conveyor is located at the conveying end of the transverse conveyor to convey the folded long cloth strips to the next workstation. The frame of the transverse conveyor is detachably connected to an end cylinder, the end cylinder power rod is detachably connected to a mounting rod, the mounting rod is detachably connected to a pushing cylinder, and the pushing cylinder power rod is detachably connected to a pushing piece on the conveying belt of the longitudinal conveyor to push the folded long cloth strips from the conveying end of the transverse conveyor to the conveying belt of the longitudinal conveyor.

[0017] By adopting the above technical solution, the overlapping long cloth strips can be effectively transferred from the horizontal conveyor to the longitudinal conveyor.

[0018] Optionally, a surface of the pressing member facing the conveyor belt of the conveyor is formed with a plurality of gas outlet holes for delivering gas.

[0019] By adopting the above technical solution, when the lower pressing piece moves upward at a relatively fast speed, the air outlet sends out airflow, so that it is not easy to generate a low-pressure area between the lower pressing piece and the overlapping long cloth strips, and it is not easy for the uppermost long cloth strip to be driven to float up slightly after being tightly pressed.

[0020] Optionally, the air outlet holes include a middle hole whose air outlet direction is perpendicular to the conveyor belt of the conveyor, and a left hole and a right hole whose air outlet directions are inclined. The middle hole is located between the left hole and the right hole, and the straight lines where the air outlet directions of the left hole and the right hole are located are located in the same plane, and the air outlet directions of the left hole and the right hole are both away from the air outlet direction of the middle hole.

[0021] By adopting the above technical solution, the upper surface of the uppermost long cloth strip can be as flat as possible.

[0022] Optionally, two ends of the pressing member are provided with end holes connected to each other for the flow of heat transfer fluid.

[0023] By adopting the above technical solution, the lower pressing piece is heated to a certain temperature, so that the uppermost long cloth strip after being pressed becomes more pliable and is not easy to return to a fluffy state.

[0024] Optionally, the end hole is further away from the conveying end of the conveyor than the air outlet hole.

[0025] By adopting the above technical solution, the U-shaped bent side of the top long cloth strip can be further aligned with the U-shaped bent side of other long cloth strips in the same vertical direction when the pressing member contacts the overlapping long cloth strips.

[0026] In summary, the present application includes at least the following beneficial effects.

[0027] After several long cloth strips are overlapped, they are moved by a conveyor to the bottom of the pressing piece, and then the pressing piece moves downward to press the upper part of the overlapped long cloth strips, so that the upper part of the originally fluffy overlapped long cloth strips is compacted, and the surface of the top long cloth strip is as flat as possible, so as to reduce the possibility of certain differences in the unfolded shape of the cotton towel products after cutting, which helps to improve the quality of the cotton towel products.

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings.

[0035] The present application embodiment discloses a conveying and arranging device for a cotton towel folding device, referring to Figure 1 , including a conveyor 1 for horizontally conveying overlapping long cloth strips, the conveyor 1 includes a transverse conveyor 43 and a longitudinal conveyor 44, the longitudinal conveyor 44 transmits along the width direction of the long cloth strips, the longitudinal conveyor 44 is located at the transmission end of the transverse conveyor 43, the transmission direction of the longitudinal conveyor 44 is perpendicular to the transmission direction of the transverse conveyor 43, the overlapping long cloth strips move on the longitudinal conveyor 44 along their own length direction, so that the overlapping long cloth strips can enter the subsequent cutting station and be cut into several sections.

[0036] Reference Figure 1 and Figure 2The two side frames of the horizontal conveyor 43 are detachably connected with the shift cylinder 4 with a vertical power rod, and the power rods of the two shift cylinders 4 are detachably connected with the same vertical shift member 41, which can be close to the conveying belt surface of the horizontal conveyor 43 so that the overlapping long cloth strips are blocked by the shift member 41. And the U-shaped bending side of the uppermost long cloth strip is close to the shift member 41. The height of the shift member 41 is higher than the height of the overlapping long cloth strips, so that when the overlapping long cloth strips abut against the shift member 41 during movement, the upper long cloth strips are not easy to fall over.

[0037] Reference Figure 1 A photoelectric sensor 42 is detachably connected to one side frame of the transverse conveyor 43. The photoelectric sensor 42 and the shift cylinder 4 are electrically connected to an external controller. The transmitting end of the photoelectric sensor 42 can be directly opposite to the end face of the overlapping long cloth strips in the length direction, and the photoelectric sensor 42 is farther away from the transmission end of the transverse conveyor 43 than the shift member 41, so that when the overlapping long cloth strips pass through the photoelectric sensor 42 first, the external controller receives the signal sent by the photoelectric sensor 42 and sends a signal to the shift cylinder 4, so that the shift member 41 can move down in time to block the overlapping long cloth strips and stay at the predetermined position.

[0038] Reference Figure 1 and Figure 3 The two side frames of the horizontal conveyor 43 can be detachably connected with a downward pressing cylinder 2 with a vertical power rod. The two downward pressing cylinders 2 power rods can be detachably connected with the same horizontal downward pressing member 3. After the stopper 41 moves down to a predetermined position for a certain period of time, the downward pressing cylinder 2 forces the downward pressing member 3 to move down, so that the bottom surface of the downward pressing member 3 can be pressed tightly against the upper part of the overlapping long cloth strips, so that the originally fluffy upper long cloth strips can become tight. The bottom surface of the downward pressing member 3 is set in an arc surface, and the arc surface of the downward pressing member 3 is convex downward, so that when the downward pressing member 3 is attached to the upper long cloth strip, the lowest point at the center of the bottom surface of the downward pressing member 3 first contacts the middle of the long cloth strip, so that the U-shaped bending side of the original uppermost long cloth strip can move toward the side of the stopper 41, so that the U-shaped bending side of the uppermost long cloth strip can tend to align with the U-shaped bending side of the long cloth strip in the same vertical direction.

[0039] Reference Figure 3 When the pressing member 3 is pressed tightly against the overlapping long cloth strips, the projection of the pressing member 3 on the conveying belt of the transverse conveyor 43 partially overlaps with the overlapping long cloth strips, and there is a distance between the projection of the pressing member 3 on the conveying belt of the transverse conveyor 43 and the U-shaped bend of the top long cloth strip, so that when the pressing member 3 moves down and presses tightly against the overlapping long cloth strips, the pressing member 3 will not contact the U-shaped bend side of the top long cloth strip, so that the U-shaped bend side of the top long cloth strip can smoothly tend to align with the U-shaped bend side of the long cloth strip in the same vertical direction.

[0040] Reference Figure 4 The bottom surface of the lower pressing member 3 is provided with several air outlet holes 49 arranged along the length direction of the long cloth strip. The air outlet holes 49 are connected to the external air compressor so as to send air toward the upper surface of the uppermost long cloth strip. The air outlet holes 49 include a row of left holes 34, a row of right holes 35 and a middle hole 33. The middle hole 33 is located between the left hole 34 and the right hole 35. The middle hole 33 sends air vertically downward. The air flow direction of the left hole 34 and the right hole 35 is inclined, and the straight line where the air outlet direction of the left hole 34 and the right hole 35 is located is located in the same plane. The air outlet directions of the left hole 34 and the right hole 35 are both far away from the air outlet direction of the middle hole 33, so that the uppermost long cloth strip can be flattened along its own length direction. The air outlet holes 49 are located on the bottom surface of the lower pressing member 3 near the stopper 41, so that the U-shaped bending side of the uppermost long cloth strip can smoothly tend to align with the U-shaped bending side of the long cloth strip in the same vertical direction.

[0041] Reference Figure 3 The vertical end surfaces at both ends of the length direction of the lower pressing member 3 are provided with end holes 31 correspondingly, and the end holes 31 are located at the side of the lower pressing member 3 away from the stopper 41 to avoid the air outlet 49. The two end holes 31 are connected and connected to the external electric water heater and the circulation pump, so that the lower pressing member 3 maintains a suitable temperature, so that after the lower pressing member 3 completes a certain period of compression and moves upward, the uppermost long cloth strip is not easy to return to a fluffy state.

[0042] Reference Figure 1 The frames on both sides of the end of the transverse conveyor 43 are detachably connected with end cylinders 45 with vertical power rods, and the upper ends of the power rods of the two end cylinders 45 are detachably connected with horizontal mounting rods 46. The mounting rods 46 are detachably connected with at least two pushing cylinders 47. The length direction of the power rods of the pushing cylinders 47 is consistent with the conveying direction of the transverse conveyor 43. The power rods of all pushing cylinders 47 are detachably connected with the same pushing piece 48 at one end away from the shifting piece 41. The pushing piece 48 is vertical, and the highest height of the longitudinal conveyor 44 is slightly lower than the height of the conveying belt of the transverse conveyor 43. When the overlapping long cloth strips move to the end of the transverse conveyor 43, the pushing piece 48 first moves down close to the conveying belt surface of the transverse conveyor 43, and then moves toward the overlapping long cloth strips to push the overlapping long cloth strips onto the conveying belt of the longitudinal conveyor 44, so that the overlapping long cloth strips can be smoothly transferred from the transverse conveyor 43 to the conveying belt of the longitudinal conveyor 44.

[0043] The conveying and sorting device of a cotton soft towel folding device of the embodiment of the present application is implemented as follows: a stack of long cloth strips after folding is sent out from the folding body to the transverse conveyor 43, and then the folded long cloth strips pass through the photoelectric sensor 42, so that the power rod of the shift cylinder 4 is extended, and then the shift member 41 is moved down and close to the conveying belt of the transverse conveyor 43, so that the folded long cloth strips are blocked by the shift member 41, and then the power rod of the pressing cylinder 2 is extended so that the pressing member 3 is pressed tightly against the upper part of the folded long cloth strips. During the process of pressing down and rising of the pressing member 3, the air outlet 49 will send out airflow to assist in leveling the top long cloth strips.

[0044] After a given time, the downward pressure cylinder 2 and the shift cylinder 4 are reset, so that the overlapping long cloth strips are smoothly conveyed to the end of the horizontal conveyor 43, and then, the power rod of the end cylinder 45 is shortened first to make the pusher 48 move downward, and then the power rod of the pusher cylinder 47 is extended so that the pusher 48 pushes the overlapping long cloth strips to the conveyor belt of the longitudinal conveyor 44, so that the overlapping long cloth strips can move along their own length direction and enter the cutting equipment of the next station for slitting.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
