[0002] Folding is an important step in the production of disposable towels and other products. Folding can be achieved by inserting a corresponding insert plate into a folding insertion channel, inserting the material to achieve folding (such as folding in half); after which the insert plate will retract and wait for the next operation; it has been found that materials folded in this way have folding quality problems when further folded to make products, such as skewed folding positions and inconsistencies in products made from the same batch of materials. Utility Model Content
[0003] In view of the technical problems existing in the background art, the present invention aims to provide a folding machine that makes the folding position of towels and other items stable and uniform and avoids positional deviation.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a folding machine, including a material folding mechanism, the material folding mechanism including a folding insert plate and a folding insertion channel, the folding insert plate being driven by a push-pull direct-movement drive device, the folding insert plate and the folding insertion channel being correspondingly matched, characterized in that: the folding insertion channel is also equipped with an anti-reverse lateral clamping component, the anti-reverse lateral clamping component being driven by a clamping drive device, the folding insert plate having a clamping avoidance opening groove, the clamping avoidance opening groove being located at the head edge of the folding insert plate, the clamping avoidance opening groove being correspondingly matched with the anti-reverse lateral clamping component.
[0005] The following optimizations or supplementary explanations can be made to the above technical solutions.
[0006] For example, at least two sets of anti-reverse side clamping components are provided, and the anti-reverse side clamping components are arranged side by side with each other. At least two sets of clamping avoidance opening slots are provided at the head edge of the folding insert plate, and the clamping avoidance opening slots are arranged side by side with each other.
[0007] For example, the folding insertion channel has channel sidewalls facing each other on both sides, with the front of the folding insert corresponding to one side of the channel sidewall and the back of the folding insert corresponding to the other side of the channel sidewall.
[0008] The anti-retraction lateral clamping component has a clamping path that moves from one side of the channel sidewall toward the other side of the channel sidewall; the clamping path is a straight path.
[0009] In addition, the folding insert is equipped with insert positioning guide rollers, which are paired and located on the front and back of the folding insert. The paired insert positioning guide rollers are provided with a positioning guide gap between each other to allow the folding insert to be matched and inserted. The insert positioning guide rollers are located on the insertion side of the folding insertion channel.
[0010] One type of folding machine includes a feeding conveyor table, a left-right folding mechanism, a right-right folding mechanism, and a front-back folding mechanism. The feeding conveyor table includes a forward feeding conveyor belt, which includes a left conveyor belt and a right conveyor belt. At least one of the left-right folding mechanism and the right-right folding mechanism employs the aforementioned material folding mechanism. The folding insertion channel of the left-right folding mechanism is a first channel arranged vertically, with its upper entrance positioned between the left and right conveyor belts. The folding insert plate of the left-right folding mechanism is a first insert plate with a vertical insertion and withdrawal action, with its front and back facing left and right respectively. The first channel is configured to cooperate with the second channel. The folding insertion channel of the up-and-down folding mechanism is a second channel with a left-right orientation, and the second channel is connected to the first channel. The folding plate of the up-and-down folding mechanism is a second plate with a left-right insertion and removal action. The front and back of the second plate face up and down respectively. The second plate is configured to cooperate with the second channel. The folding insertion channel of the front-and-back folding mechanism is a third channel with a up-and-down orientation, and the third channel is connected to the second channel. The folding plate of the front-and-back folding mechanism is a third plate with a up-and-down insertion and removal action. The front and back of the third plate face forward and backward respectively. The third plate is configured to cooperate with the third channel.
[0011] For example, the first channel is located between the left and right side plates, the second channel is located between the upper and lower side plates, and the third channel is located between the front and rear conveyor belts. The front and rear conveyor belts work together to form the material clamping and lowering conveying device of the third channel. The second channel is connected to the right side of the first channel, and the left side of the first channel has a left opening for the second insert plate to operate.
[0012] The third channel is connected to the lower side of the second channel, and the upper side of the second channel is provided with an upper opening for the third insert plate to operate.
[0013] For example, the feeding conveyor has a towel laying station, a spraying station, a towel water control station and a folding and coordinating station arranged in sequence, with the upper entrance of the first channel located at the folding and coordinating station.
[0014] For example, the towel laying station is equipped with a first conveyor belt, the spraying station and the towel water control station are equipped with a second conveyor belt, the spraying station is equipped with a spraying component, the spraying component is positioned above the second conveyor belt, the towel water control station is equipped with a water control component, the towel water control station is positioned above the second conveyor belt, the first conveyor belt is connected to the second conveyor belt, and the second conveyor belt is connected to the forward feeding conveyor belt.
[0015] For example, the water control component includes a water control roller, which is positioned above the second conveyor belt. A bottom roller is also provided on the inner side of the second conveyor belt, and the bottom roller is positioned vertically corresponding to the water control roller. An auxiliary conveyor roller is also provided on the output side of the water control roller. A conveyor rope is driven and connected between the water control roller and the auxiliary conveyor roller, and the conveyor ropes are arranged side by side.
[0016] The beneficial effect of this utility model is that it can be used to solve the problem of preventing material displacement after folding when folding products such as towels. It was found that the main reason for this problem is that when the folding insert is pulled out and retracted from the folding insertion channel, it is very easy to cause the material to move (after folding), resulting in problems such as the material being pulled back, deviating from its position, tilting, and inconsistent position. This folding machine is equipped with an anti-retraction lateral clamping component and a clamping and avoiding opening groove is opened on the folding insert to solve this problem.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0036] Referring to the accompanying drawings, an embodiment of this invention provides a folding machine that can be used for folding materials such as cotton towels and non-woven towels. The folding machine includes a material folding mechanism 4, which includes a folding insert plate 40 and a folding insertion channel 41. The folding insert plate 40 is connected to an insertion and removal linear drive device 42. The folding insert plate 40 and the folding insertion channel 41 are correspondingly matched. The folding insert plate 40 is used to insert materials into the folding insertion channel 41 to achieve folding of materials (such as towels). The folding insert plate 40 is driven by the insertion and removal linear drive device 42 (such as a motor or cylinder) to move linearly back and forth to insert into and withdraw from the folding insertion channel 41. This is a mature technology.
[0037] The problem was found that the material position was skewed after folding, and the position of the same batch of materials was inconsistent after folding. In order to solve this problem, in this embodiment, the folding insertion channel 41 is also equipped with an anti-retraction lateral clamping component 43. The anti-retraction lateral clamping component 43 is connected to the clamping drive device 44 (such as a cylinder or motor). The clamping drive device 44 drives the anti-retraction lateral clamping component 43 to move, so that the anti-retraction lateral clamping component 43 performs lateral clamping and returns to its original position (i.e., returns to wait for the next action). The folding insert plate 40 is provided with a clamping avoidance opening slot 45. The clamping avoidance opening slot 45 is located at the head edge of the folding insert plate 40 and is correspondingly provided with the anti-retraction lateral clamping component 43 (i.e., the clamping avoidance opening slot 45 can be used to avoid the movement of the anti-retraction lateral clamping component 43). Its working principle is as follows: When the folding insert plate 40 inserts the material into the folded position, the anti-retraction lateral clamping component 43 can enter the folding insertion channel 41 (laterally) and can clamp the material laterally according to the position of the clamping clearance opening slot 45, which can cooperate to clamp the material (inserted and folded by the folding insert plate 40); the existence of the clamping clearance opening slot 45 can avoid the position, and when the anti-retraction lateral clamping component 43 moves to clamp the material, the folding insert plate 40 does not need to retract first. After the material is clamped and fixed by the anti-retraction lateral clamping component 43, it does not affect the retraction of the folding insert plate 40. When the folding insert plate 40 retracts from the folding insertion channel 41 (pulled out), it will not move (complete the folding) the clamped material, avoiding the folded material from being misaligned. The position of the folded material is more stable, and the position of the same batch of materials is relatively uniform when folded, and it is less likely to have deviation or large deviation problems, making it more practical.
[0038] This folding machine can be used to solve the problem of preventing material displacement after folding products such as towels. It was found that the main reason for this problem is that when the folding insert 40 is pulled out and retracted from the folding insertion channel 41, it is very easy to cause material displacement (after folding), resulting in problems such as material being pulled back, deviating from its position, tilting, and inconsistent position. The folding machine is equipped with an anti-retraction lateral clamping component 43 and a clamping and avoiding opening slot 45 is opened on the folding insert 40 to solve this problem.
[0039] Based on the above embodiments, the following optimizations or further explanations can be made.
[0040] The anti-retraction lateral clamping components 43 are provided in at least two sets, arranged side by side. At least two sets of clamping and avoiding opening slots 45 are correspondingly provided at the head edge of the folding insert plate 40, arranged side by side, meaning the clamping and avoiding opening slots 45 correspond to the anti-retraction lateral clamping components 43. The structural layout is relatively reasonable, and the side-by-side structure provides more balanced force. The head edge of the folding insert plate 40 refers to the part that is first inserted into the folding insertion channel 41. Typically, the head edge of the folding insert plate 40 can be set as a straight edge or a straight edge with concave teeth.
[0041] The folding insertion channel 41 has channel sidewalls facing each other on both sides. The front of the folding insert plate 40 corresponds to one channel sidewall, and the back of the folding insert plate 40 corresponds to the other channel sidewall. Typically, the folding insert plate 40 adopts a flat, thin plate structure.
[0042] The anti-retraction lateral clamping component 43 has a clamping path that moves from one side of the channel wall to the other side of the channel wall. The clamping path is usually a straight path, that is, the anti-retraction lateral clamping component 43 moves back and forth along a straight path to clamp and retract the material; the structure is relatively simpler and more reasonable.
[0043] In addition, the folding insert 40 is equipped with insert positioning guide rollers 46. These rollers are paired and positioned on the front and back sides of the folding insert 40. The two rollers on the front and back sides of the folding insert 40 are paired together, with a positioning guide gap between them for the folding insert 40 to be inserted and removed. The folding insert 40 can pass through the positioning guide gap between the paired rollers. The paired rollers work together on both the front and back sides to support and guide the folding insert 40, making it more stable during insertion, removal, and return. This prevents the folding insert 40 from shaking or vibrating during operation and avoids problems such as material deviation, skewing, or inconsistent positioning during the folding process. The insert positioning guide rollers 46 can be located on the insertion side of the folding insertion channel 41, resulting in a relatively reasonable structure that facilitates assembly.
[0044] One type of folding machine includes a feeding conveyor 5, a left and right folding mechanism 1, a right and left folding mechanism 2, and a front and back folding mechanism 3. The feeding conveyor 5 includes a forward feeding conveyor belt 50, which is used to advance the material. The forward feeding conveyor belt 50 includes a left conveyor belt 51 and a right conveyor belt 52 (located on the left and right sides respectively), and the left conveyor belt 51 and the right conveyor belt 52 can advance the material synchronously. At least one of the left and right folding mechanisms 1 and the right and left folding mechanisms 2 adopts the material folding mechanism 4 (which has a material anti-backflow function), that is, the left and right folding mechanism 1 adopts the material folding mechanism 4, or the right and left folding mechanism 2 adopts the material folding mechanism 4, or both of them adopt the material folding mechanism 4.
[0045] The folding insertion channel 41 of the left and right folding mechanism 1 is a first channel 10 arranged vertically. The upper entrance 16 of the first channel 10 is located between the left conveyor belt 51 and the right conveyor belt 52. The folding insert plate 40 of the left and right folding mechanism 1 is a first insert plate 11 that performs vertical insertion and removal. The upper entrance 16 of the first channel 10 is used for the insertion and removal of the first insert plate 11. The front and back of the first insert plate 11 face left and right respectively. The first insert plate 11 is correspondingly matched with the first channel 10. The corresponding insertion and removal linear drive device 42 (such as a cylinder or motor linear module 12) will drive the first insert plate 11 to perform vertical insertion and removal. The first insert plate 11 descends and inserts into the first channel 10. The first insert plate 11 rises and is removed from the first channel 10. The left and right folding mechanism 1 inserts the material from the left conveyor belt 51 and the right conveyor belt 52 (downward) into the first channel 10 to complete the left and right folding of the material, thus completing the first fold.
[0046] In this design, the folding insertion channel 41 of the vertical folding mechanism 2 is a second channel 20 arranged in a left-right direction, which is connected to the first channel 10. The folding insert 40 of the vertical folding mechanism 2 is a second insert 21 with left-right insertion and removal action. The front and back of the second insert 21 face up and down respectively. The second insert 21 is correspondingly matched with the second channel 20. The corresponding insertion and removal linear movement drive device 42 (such as a cylinder or motor linear module 22) will drive the second insert 21 to perform left-right insertion and removal actions. For example, in the figure, the second insert 21 moves to the left to insert into the second channel 20, and the second insert 21 moves to the right to pull out of the second channel 20. The first channel 10 is connected to the second channel 20. The material that has been folded left and right in the first channel 10 (the material is in a vertical direction) can be inserted from the first channel 10 into the second channel 20 by the second insert 21 (of the vertical folding mechanism 2) to complete the material's vertical folding and complete the second fold.
[0047] Among them, the folding insertion channel 41 of the front and rear folding mechanism 3 is a third channel 30 arranged vertically, which is connected to the second channel 20. The folding plate of the front and rear folding mechanism 3 is a third plate 31 with vertical insertion and removal action. The front and back of the third plate 31 face forward and backward respectively. The third plate 31 is arranged in correspondence with the third channel 30. The corresponding insertion and removal direct movement drive device 42 (such as a cylinder 32 or a motor) will drive the third plate 31 to perform vertical insertion and removal action. The second channel 20 is connected to the third channel 30. The material that has been folded vertically in the second channel 20 (the material is in a left-right orientation) can be inserted from the second channel 20 into the third channel 30 by the third plate 31 (of the front and rear folding mechanism 3) to complete the front and rear folding of the material, thus completing the third fold.
[0048] The first channel 10 can be located between the left side panel 13 and the right side panel 14, meaning the space between the left and right side panels 13 and 14 can be used to form the first channel 10. The distance between the left side panel 13 and the right side panel 14 can be adjusted as needed, such as by adjusting the distance on the guide rod. The second channel 20 is located between the upper side panel 23 and the lower side panel 24, meaning the space between the upper side panel 23 and the lower side panel 24 can be used to form the second channel 20. The distance between the upper side panel 23 and the lower side panel 24 can be adjusted as needed, such as by adjusting the distance on the guide rod. The third channel 30 is located between the front conveyor belt 33 and the rear conveyor belt 34. That is, the space between the front conveyor belt 33 and the rear conveyor belt 34 can be used to form the third channel 30. The front conveyor belt 33 and the rear conveyor belt 34 each have a belt body part that conveys from top to bottom. The third channel 30 is formed by the front and rear opposite belt body parts. The front conveyor belt 33 and the rear conveyor belt 34 cooperate to form the clamping and downward conveying device of the third channel 30. The front conveyor belt 33 and the rear conveyor belt 34 can also clamp the material inserted into the third channel 30 and convey it downward. The direct output is more efficient than the direct downward output using the third insert plate 31. For subsequent processing (such as packaging into bags), a lower receiving conveyor belt 35 can be configured at the lower exit of the third channel 30. The lower receiving conveyor belt 35 and the lower exit can be connected by a (such as an arc-shaped) guide plate 36, which guides the folded material to turn. A conveying auxiliary pressing component 331 can be set above the lower receiving conveyor belt 35. The front feeding part of the front conveyor belt 33 can be directly used as the conveying auxiliary pressing component 331 to cooperate with the lower receiving conveyor belt 35 to output the material to the subsequent packaging machine.
[0049] For example, the second channel 20 connects to the right side of the first channel 10, and the left side of the first channel 10 has a left opening 15 for the second insert 21 (insert) to operate, such as a left opening 15 on the left side plate 13; the third channel 30 connects to the lower side of the second channel 20, and the upper side of the second channel 20 has an upper opening 25 for the third insert 31 (insert) to operate, such as an upper opening 25 on the upper side plate 23. The upper side plate 23 and the lower side plate 24 can be made of transparent material (such as plexiglass) to facilitate observation of the internal folding. The second channel 20 connects to the right side of the first channel 10, such as a right opening on the right side plate 14 of the first channel 10 for connection; the third channel 30 connects to the lower side of the second channel 20, such as a lower opening on the lower side plate 24 of the second channel 20 for connection.
[0050] In addition, the feeding conveyor 5 has a towel laying station 6, a spraying station 7, a towel water control station 8, and a folding station 9 arranged in sequence. The upper entrance 16 of the first channel 10 is located at the folding station 9. The station layout is reasonable and can complete the folding of wet towels. The towel laying station 6 is used to lay out the towels one by one. The spraying station 7 is used to spray the towels to make them wet towels. The towel water control station 8 is used to control the water content of the towels after spraying so that the moisture content of the towels reaches the set range. The folding station 9 is used to fold the towels. The towel laying station 6 is equipped with a first conveyor belt 60, and the spraying station 7 and the towel water control station 8 are equipped with a second conveyor belt 78. The spraying station 7 is equipped with a spraying component 70 (such as a spray pipe with spray holes at the bottom). The spraying component 70 is positioned above the second conveyor belt 78. The towel water control station 8 is equipped with a water control component 80. The towel water control station 8 is positioned above the second conveyor belt 78. The first conveyor belt 60 is connected to the second conveyor belt 78, and the second conveyor belt 78 is connected to the forward feeding conveyor belt 50 to realize the continuous conveying of towel materials. The water control component 80 includes a water control roller 81, which is positioned above the second conveyor belt 78. During the process of conveying a towel, the water control roller 81 applies pressure to the towel from above to control water and squeeze out excess water. A bottom roller 82 is also provided on the inner side of the second conveyor belt 78. The bottom roller 82 is positioned vertically corresponding to the water control roller 81. The bottom roller 82 can support the towel below and work with the water control roller 81 to apply pressure to control water, resulting in more stable water control pressure. In addition, the output side of the water control roller 81 is equipped with an auxiliary conveying roller 83. A conveying rope 84 is driven and connected between the water control roller 81 and the auxiliary conveying roller 83. The conveying ropes 84 are arranged side by side. The auxiliary conveying roller 83 is driven and connected to the water control roller 81 by the conveying ropes 84 and operates together. The conveying ropes 84 can also limit the sprayed towels from above to facilitate forward output, preventing the wet towels from shifting or getting tangled on the water control roller 81. The water control roller 81 can apply downward pressure using its own weight or with a spring. The pressure can even be adjusted by adjusting the spring force to regulate the water control pressure. Annular grooves can be provided on the water control roller 81 and the auxiliary conveying roller 83 for the conveying ropes 84 to embed and connect between the rollers. Multiple water control rollers 81 can be set in the figure, and the water control rollers 81 are also connected to each other by conveying ropes 84. Water collection boxes 87 can be installed below the spraying station 7, the towel water control station 8, etc. The problem of material movement of wet towels needs to be solved.
