Description

Technical Field

[0001] This application relates to the field of folding machine technology, specifically to a three-in-one folding machine with two horizontal pressure rollers. Background Technology

[0002] Most linen folding machines on the market today use a frame as the core support structure, equipped with a horizontal feeding assembly, a horizontal feeding assembly, and a fabric output assembly. Some machines also include a longitudinal folding assembly to complete the entire folding process. The feeding assembly often uses a transmission method that combines pressure rollers and a conveyor belt. The conveyor belt material is often cotton (because cotton has a certain degree of flexibility, which can be adapted to the needs of linen conveying).

[0003] During operation, the linens are first initially fed into the equipment via the first horizontal feeding component, then fed into the second horizontal feeding component to complete the second horizontal fold, and finally output by the output component. Some equipment will connect the vertical folding process after the second horizontal fold to achieve multi-dimensional folding of the linens.

[0004] However, existing folding machines still have the following problems that need to be solved:

[0005] 1. Insufficient control over the flatness of linens after horizontal folding. In existing equipment, there is a lack of a dedicated flattening structure between the horizontal folding assembly and the vertical folding process (or the output assembly). After the linens are folded horizontally, they directly enter the next stage. Furthermore, there are easy gaps or angular deviations in the connection between the horizontal folding assembly, the horizontal folding assembly, and the output assembly, which causes wrinkles to form in the linens during the transition process. This makes it impossible to guarantee the flatness before the vertical folding, thus affecting the appearance and quality of the final folded product.

[0006] 2. Inadequate conveyor belt tensioning function. Since conveyor belts are mostly made of cotton, they are prone to stretching and deformation after prolonged use. However, the pressure rollers of the existing horizontal feeding assembly are mostly fixed, lacking an adaptive tensioning structure. This fails to compensate for the stretching of the conveyor belt in a timely manner, leading to decreased transmission stability after the belt loosens. This not only causes linen conveying deviation but also reduces the positional accuracy of the horizontal folding. The folding effect deteriorates significantly with increased equipment usage time, requiring frequent manual stops for adjustment, thus impacting production efficiency. Utility Model Content

[0007] The purpose of this utility model is to provide a three-in-one folding machine with two horizontal pressure rollers to solve the problems mentioned in the background art.

[0008] The technical solution adopted by this application to solve its technical problem is:

[0009] The three-in-one folding machine with two horizontal pressure rollers includes a folding frame, a horizontal first feeding assembly installed on one side of the folding frame, a horizontal second feeding assembly installed inside the folding frame, the horizontal second feeding assembly being attached to one side of the horizontal first feeding assembly, and a fabric output assembly installed at the bottom of the folding frame, the top surface of the end of the fabric output assembly being attached to the bottom of the horizontal second feeding assembly.

[0010] The horizontal fabric feeding assembly includes a third pressure roller, a fourth pressure roller, a fifth pressure roller, and a second conveyor belt. The third and fourth pressure rollers are fixedly installed on the folding frame, and the fifth pressure roller is movably installed on the folding frame. The third, fourth, and fifth pressure rollers are all connected by the second conveyor belt.

[0011] Preferably, the horizontal fabric feeding assembly includes a support frame, a first pressure roller, a first conveyor belt, and a second pressure roller. The support frame is installed on the side wall of the folding frame, and the end of the support frame is rotatably mounted to the first pressure roller. The second pressure roller is rotatably mounted on the top of the folding frame, and the first pressure roller is connected to the second pressure roller via the first conveyor belt.

[0012] Preferably, the first conveyor belt is inclined to the folding frame.

[0013] Preferably, the fabric output assembly includes a sixth pressure roller, a seventh pressure roller, and a third conveyor belt. The sixth and seventh pressure rollers are rotatably mounted on the bottom of the folding frame, and the sixth pressure roller is connected to the seventh pressure roller via the third conveyor belt.

[0014] Preferably, the sixth and seventh pressure rollers are horizontally mounted on the folding frame.

[0015] Preferably, both ends of the fourth and sixth pressure rollers are mounted on the folding frame via the first bearing seat, and the fourth and sixth pressure rollers are arranged vertically on the folding frame;

[0016] Preferably, the side wall of the folding frame is provided with a sliding groove, and the two ends of the fifth pressure roller are fixedly installed with second bearing seats, and the two ends of the second bearing seats are slidably installed in the sliding groove by bolts.

[0017] The beneficial effects of this application are:

[0018] 1. This technical solution eliminates gaps and potential deviations during linen conveying by ensuring that the side walls of the first horizontal feeding assembly and the second horizontal feeding assembly are in contact, and that the bottom of the second horizontal feeding assembly is in contact with the top surface of the end of the output assembly. This ensures continuous linen conveying. In the second horizontal feeding assembly, the third, fourth, and fifth pressure rollers, in conjunction with the second conveyor belt, form a dedicated flattening area. After the linen is folded horizontally, it is continuously subjected to the coordinated compression of the pressure rollers and the conveyor belt as it is conveyed to the output assembly by the second conveyor belt. This effectively smooths out the wrinkles caused by the folding, ensuring that the linen has sufficient flatness before entering the longitudinal folding process, thus significantly improving the quality of the final folded product.

[0019] 2. This technical solution designs the fifth pressure roller of the horizontal second fabric feeding assembly as a movable structure. By opening a sliding groove on the side wall of the folding frame, and cooperating with the second bearing seats and sliding bolts at both ends of the fifth pressure roller, the fifth pressure roller can move freely up and down along the sliding groove. When the second conveyor belt stretches due to long-term use, the fifth pressure roller automatically slides down along the sliding groove under its own gravity. By increasing the length of the conveyor belt around the roller to compensate for the stretching, the automatic tensioning of the conveyor belt is achieved without the need for manual stopping for adjustment. This solves the problem of the imperfect tensioning function of the existing equipment, reduces equipment maintenance costs, and ensures the stability of the folding effect during long-term continuous operation.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0037] Please see Figure 1-4 The embodiments provided by this utility model are as follows:

[0038] The three-in-one folding machine with two horizontal pressure rollers includes a folding frame 1, a horizontal feeding assembly 2 installed on one side of the folding frame 1, a horizontal feeding assembly 3 installed inside the folding frame 1, the horizontal feeding assembly 3 being attached to one side of the horizontal feeding assembly 2, and a fabric output assembly 4 installed at the bottom of the folding frame 1, the top surface of the end of the fabric output assembly 4 being attached to the bottom of the horizontal feeding assembly 3.

[0039] On one side of the folding frame 1, a horizontal feeding assembly 2 is installed to initially transport the linens into the device. Inside the folding frame 1, a horizontal feeding assembly 3 is installed to realize the horizontal folding of the linens and subsequent flatness optimization. It is also closely fitted with the horizontal feeding assembly 2 to ensure the continuity of the linen transport process. The output assembly 4 at the bottom of the folding frame 1 is responsible for outputting the linens that have been folded and flattened. Its top end is fitted with the bottom of the horizontal feeding assembly 3 to ensure that the linens can smoothly transition from the horizontal feeding assembly 3 to the output assembly 4.

[0040] The horizontal fabric feeding assembly 2 includes a support frame 21, a first pressure roller 22, a first conveyor belt 23, and a second pressure roller 24. The support frame 21 is installed on the side wall of the folding frame 1, and the end of the support frame 21 is rotatably installed with the first pressure roller 22. The second pressure roller 24 is rotatably installed on the top of the folding frame 1. The first pressure roller 22 is connected to the second pressure roller 24 through the first conveyor belt 23, and the first conveyor belt 23 is inclined to the folding frame 1.

[0041] During equipment operation, a power source (such as a motor) drives the first pressure roller 22 to rotate via a transmission mechanism. Since the first conveyor belt 23 connects the first pressure roller 22 and the second pressure roller 24, the first conveyor belt 23 starts to operate under the drive of the first pressure roller 22, which in turn drives the second pressure roller 24 to rotate synchronously. Linen is placed on the first conveyor belt 23, and as the conveyor belt rotates, the linen is tilted upwards and conveyed to the horizontal second-level fabric feeding assembly 3.

[0042] The fabric output assembly 4 includes a sixth pressure roller 41, a seventh pressure roller 42, and a third conveyor belt 43. The sixth pressure roller 41 and the seventh pressure roller 42 are rotatably mounted on the bottom of the folding frame 1. The sixth pressure roller 41 is connected to the seventh pressure roller 42 via the third conveyor belt 43. The sixth pressure roller 41 and the seventh pressure roller 42 are horizontally mounted on the folding frame 1. After the linen completes the folding and flattening process in the horizontal second fabric feeding assembly 3, it enters the fabric output assembly 4. The power source drives the sixth pressure roller 41 to rotate, which in turn drives the third conveyor belt 43 to rotate. The third conveyor belt 43 then drives the seventh pressure roller 42 to rotate synchronously. Under the action of the conveyor belt, the linen is horizontally transported to the outside of the device, completing the entire folding process.

[0043] The horizontal fabric feeding assembly 3 includes a third pressure roller 31, a fourth pressure roller 32, a fifth pressure roller 33, and a second conveyor belt 34. The third pressure roller 31 and the fourth pressure roller 32 are fixedly installed on the folding frame 1, and the fifth pressure roller 33 is movably installed on the folding frame 1. The third pressure roller 31, the fourth pressure roller 32, and the fifth pressure roller 33 are all connected by the second conveyor belt 34.

[0044] The power source drives the third pressure roller 31 to rotate, and the third pressure roller 31 drives the second conveyor belt 34 to rotate, which in turn causes the fourth pressure roller 32 and the fifth pressure roller 33 to rotate synchronously with the operation of the conveyor belt. When the linen is conveyed from the first horizontal feeding assembly 2 to the second horizontal feeding assembly 3, the linen is folded horizontally under the drive of the second conveyor belt 34.

[0045] Both ends of the fourth pressure roller 32 and the sixth pressure roller 41 are mounted on the folding frame 1 through the first bearing seat 5. The fourth pressure roller 32 and the sixth pressure roller 41 are arranged vertically on the folding frame 1. During the folding process, the fourth pressure roller 32 and the sixth pressure roller 41 are arranged vertically to guide and limit the linen, so that when the linen slides onto the fabric output component 4, it can be flattened and the flatness of the linen can be improved.

[0046] The folding frame 1 has a sliding groove 11 on its side wall. The two ends of the fifth pressure roller 33 are fixedly installed with second bearing seats 6. The two ends of the second bearing seats 6 are slidably installed in the sliding groove 11 by bolts 7. As the machine is used for a long time, if the second conveyor belt 34 stretches, the fifth pressure roller 33 will move downward along the sliding groove 11 under the action of gravity because the fifth pressure roller 33 is movably installed on the folding frame 1 and the second bearing seats 6 at both ends slide in the sliding groove 11 by bolts 7. This will tension the second conveyor belt 34 and ensure the normal transmission of the conveyor belt and the folding effect of the linens.

[0047] Meanwhile, after the linen is folded horizontally twice, the second conveyor belt 34 continues to operate, conveying the linen to the fabric output assembly 4. During this process, the linen will pass through a flattening area formed by the third pressure roller 31, the fourth pressure roller 32 and the fifth pressure roller 33 to flatten the linen and improve its flatness.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
