Description

Technical Field

[0001] The utility model relates to a towel folding device, specifically a towel horizontal folding device, and belongs to the technical field of textile product packaging. Background Art

[0002] With the gradual development of technology, many manufacturing industries have gradually replaced manual work with automated production lines, which can not only reduce the labor cost of enterprises, improve production safety, but also achieve efficient and error-free work, bringing huge economic benefits to enterprises.

[0003] As one of the essential daily necessities for people, towels have a large application volume, high demand, wide application scenarios, and the market supply and demand are also increasing continuously. At the same time, a large number of devices related to towel production and manufacturing have emerged. As people's daily necessities, towels not only need to improve production efficiency during the production and manufacturing process, but also pay attention to the sanitary environment during towel production, packaging, and transportation to ensure the cleanliness of towels, so as to ensure the health and safety of users. At the same time, it can also give users a good visual experience when choosing to buy, and enhance the purchasing desire of buyers.

[0004] At present, a large number of towel packaging devices have emerged, including various towel folding devices. For example, Chinese Patent Application CN 116161480 A, a textile finished product folding device, and CN 116135716 A, a towel folding machine. The former pays more attention to cost control considering production cost issues. The folding effect of the towel in this solution is achieved by the misaligned cooperation of the second support component and the first support component. However, manual feeding and product removal are required before and after folding. Especially when removing the product, there is no good holding of the product, and it does not disclose how to ensure the regularity of the product. The latter proposes a structure for automatic feeding and receiving, but the device has a complex structure. The first folding insert plate of the first folding mechanism punches downward to fold the towel for the first time along the length direction. Its folding method is similar to the solution provided by the former, which is to punch from above to the middle of the towel to achieve towel folding. It is necessary to maintain the state of the towel to avoid uneven folding caused by its collapse under gravity. Therefore, an additional structure for stabilizing the vertically placed towel needs to be set, increasing the design and production cost. Summary of the Invention

The conveying assembly includes a high-position conveying device and a low-position conveying device arranged in a vertically offset manner. The high-position conveying device and the low-position conveying device share the same power source. By means of two conveying devices with different heights, namely the high-position conveying device and the low-position conveying device, a height difference between the two structures is utilized, and an L-shaped limiting plate is arranged in the interval where the two are vertically offset. Then, by arranging a cylinder and a push rod, when the towel passes through the high-position conveying device and the low-position conveying device, it is pushed outwards, and the horizontal folding of the towel is realized by using the limiting plate. Whether the towel is placed horizontally or vertically, the automatic folding of the towel can be efficiently realized.

[0006] Technical Solution: A towel horizontal folding device includes a mounting frame and a conveying assembly arranged on the mounting frame. The conveying assembly includes a high-position conveying device and a low-position conveying device arranged in a vertically offset manner. The high-position conveying device and the low-position conveying device share the same power source;

[0007] Both the high-position conveying device and the low-position conveying device include a transmission roller assembly and a conveyor belt. The transmission roller assembly is rotatably installed on the mounting frame and is in transmission connection with the output end of the power source. The conveyor belt is sleeved outside the transmission roller assembly;

[0008] A vertical frame spanning the high-position conveying device and the low-position conveying device is arranged above the mounting frame. An L-shaped limiting plate is arranged on the vertical frame. The limiting plate is arranged above the low-position conveying device, and its horizontal part is located between the high-position conveying device and the low-position conveying device;

[0009] A push rod assembly is fixedly arranged on the mounting frame. The push rod assembly includes a cylinder fixed on the mounting frame. The output end of the cylinder is connected to a horizontal push rod. The horizontal push rod is arranged between the high-position conveying device and the horizontal part of the limiting plate.

[0010] In the utility model, by means of two conveying devices with different heights, namely the high-position conveying device and the low-position conveying device, a height difference between the two structures is utilized, and an L-shaped limiting plate is arranged in the interval where the two are vertically offset. Then, by arranging a cylinder and a push rod, when the towel passes through the high-position conveying device and the low-position conveying device, it is pushed outwards, and the horizontal folding of the towel is realized by using the limiting plate. Whether the towel is placed horizontally or vertically, the automatic folding of the towel can be efficiently realized. To ensure the sanitary environment during the production process and improve the production quality of the towel, the power source for driving the push rod is selected as a cylinder, which can realize rapid reciprocating motion, can quickly follow the work even when the towel conveying speed is relatively fast, and is free of pollution.

[0011] Preferably, the high-position conveying device is installed on the mounting frame through a high-position mounting component, and the low-position conveying device is installed on the mounting frame through a low-position mounting component;

[0012] The low-position mounting assembly includes a low-position cross frame arranged on the upper side of the middle part of the mounting frame and at least two low-position vertical plates arranged on the side of the mounting frame away from the high-position conveying device. At least two transverse guide grooves corresponding to the positions of the low-position vertical plates are formed on the side surface of the low-position cross frame, and longitudinal guide grooves corresponding to the positions of the transverse guide grooves are formed on the low-position vertical plates.

[0013] The high-position mounting assembly includes a high-position cross frame fixedly connected to the upper side of the low-position cross frame and at least two high-position vertical plates arranged on the side of the mounting frame away from the low-position conveying device. At least two transverse guide grooves corresponding to the positions of the high-position vertical plates are formed on the side surface of the high-position cross frame, and longitudinal guide grooves corresponding to the positions of the transverse guide grooves are formed on the high-position vertical plates.

[0014] By correspondingly setting different low-position mounting assemblies and high-position mounting assemblies, the difference in height is realized, so that the towels are in a state of uneven upper and lower heights when being conveyed to the folding section, and the towels located on the low-position conveying device can be located below the limiting plate, so as to effectively fold when the push rod is pushed out, and the folding effect is good. The transverse guide grooves arranged on the low-position cross frame and the high-position cross frame play a role in guiding installation and upper and lower limiting. The transverse guide grooves provide an installation basis and a convenient installation environment for the transmission roller assembly, and can be finely adjusted to adapt to different situations; the longitudinal guide grooves of the low-position vertical plates and the high-position vertical plates play a role in lateral limiting of the transmission roller assembly, and cooperate with the transverse guide grooves to realize multi-directional limiting, ensuring the installation stability of the transmission roller assembly, thereby ensuring production safety and production efficiency.

[0015] Preferably, the low-position vertical plates and the high-position vertical plates have the same structure, and the length of the longitudinal guide grooves of the low-position vertical plates and the high-position vertical plates is the sum of the heights of the high-position cross frame and the low-position cross frame.

[0016] In order to reduce production costs, the structures of the high-position vertical plates and the low-position vertical plates are set to the same structure, and the longitudinal guide grooves for limiting are raised to the sum of the heights of the two cross frames, so that the limiting effect can be realized at each installation position, further improving the installation convenience, and at the same time, a good installation basis can be provided for the vertical frame.

[0019] By setting up the tensioning rollers, the tension of the conveyor belt can be well adjusted. Moreover, two feeding cross frames are used to provide an installation basis for the conveyor roller assembly, improving the installation convenience. The high-position conveyor device and the low-position conveyor device share the same driving roller, tensioning roller, and one driven roller on the side close to the driving roller, enabling their actions to be unified, capable of synchronous operation and stop, and ensuring the quality and smoothness of the folding work.

[0020] Preferably, the low-position cross frame, high-position cross frame, and feeding cross frame have the same structure.

[0021] Setting the structures of the three cross frames to be the same can reduce production costs and can provide a stable installation basis for the corresponding components.

[0022] Preferably, the high-position cross frame further includes at least one limiting hole, and the output end of the cylinder passes through the limiting hole and is connected to the transverse push rod.

[0023] The structure of the limiting hole is the same as that of the transverse guide groove, which is more convenient in production. It is only necessary to fix the cylinder end firmly. Through the setting of the limiting hole, the up-and-down deviation of the output end of the cylinder can be avoided, and the collision between the transverse push rod and the limiting plate can be avoided, preventing equipment damage and affecting the towel folding quality.

[0024] Preferably, a guide seat corresponding to the position of the limiting hole is provided on the high-position cross frame near the cylinder side.

[0026] Preferably, it further includes a control host, an article detector installed at the lower end of the vertical frame, and a time relay installed between the control host and the cylinder. The control host is respectively connected to the time relay and the article detector through signal transmission lines, and the time relay is connected to the cylinder through a signal transmission line.

[0027] In order to further achieve automated production, the article detector can detect whether there is a towel conveyed to the folding area on the conveyor belt. The folding area is the working area of the limiting plate and the transverse push rod. Through the feedback of the article detector, the control host sends a signal to control the cylinder to push, driving the transverse push rod to extend. Among them, the time relay adjusts different set times according to the running speed of the conveyor belt to ensure that the push rod is pushed out after the towel completely enters the working area to achieve towel folding, ensuring the folding efficiency and folding quality.

[0028] Beneficial effects: The utility model includes a high-position conveying device and a low-position conveying device with different heights. By utilizing the height difference between the two structures and arranging an L-shaped limiting plate in the interval where the heights are staggered, and then setting a cylinder and a push rod, when the towel passes through the high-position conveying device and the low-position conveying device, it is pushed outwards, and the towel is laterally folded by using the limiting plate. Whether the towel is placed horizontally or vertically, the automatic folding of the towel can be efficiently realized.

[0029] In order to further realize automatic production, an article detector can detect whether there is a towel conveyed to the folding area on the conveyor belt. The folding area is the working area of the limiting plate and the lateral push rod. Through the feedback of the article detector, the control host sends a signal to control the cylinder to push, driving the lateral push rod to extend. Among them, the time relay adjusts different set times according to the running speed of the conveyor belt to ensure that the push rod is pushed out after the towel completely enters the working area to realize towel folding, and to ensure the folding efficiency and folding quality.

[0039] As Figure 1 and 5 shown, a towel horizontal folding device includes a mounting frame 1 and a conveying assembly provided on the mounting frame 1. The conveying assembly includes a high-position conveying device 2 and a low-position conveying device 3 arranged in a vertically offset manner, and the high-position conveying device 2 and the low-position conveying device 3 share the same power source 4;

[0040] Both the high-position conveying device 2 and the low-position conveying device 3 include a transmission roller assembly 5 and a conveyor belt 6. The transmission roller assembly 5 is rotatably installed on the mounting frame 1 and is in transmission connection with the output end of the power source 4, and the conveyor belt 6 is sleeved outside the transmission roller assembly 5;

[0041] A vertical frame 8 spanning the high-position conveying device 2 and the low-position conveying device 3 is provided above the mounting frame 1. An L-shaped limiting plate 61 is provided on the vertical frame 8. The limiting plate 61 is arranged above the low-position conveying device 3 and its horizontal part is located between the high-position conveying device 2 and the low-position conveying device 3;

[0042] A push rod assembly 7 is fixedly provided on the mounting frame 1. The push rod assembly 7 includes a cylinder 71 fixed on the mounting frame 1, and the output end of the cylinder 71 is connected to a horizontal push rod 72. The horizontal push rod 72 is arranged between the high-position conveying device 2 and the horizontal part of the limiting plate 61.

[0043] The utility model includes two conveying devices with different heights, namely a high-position conveying device 2 and a low-position conveying device 3. By utilizing the height difference between the two structures and arranging an L-shaped limiting plate 61 in the interval where their heights are staggered, and then setting a cylinder 71 and a push rod, when the towel passes through the high-position conveying device 2 and the low-position conveying device 3, it is pushed outwards, and the towel is transversely folded by using the limiting plate 61. Whether the towel is placed horizontally or vertically, the automatic folding of the towel can be efficiently realized. In order to ensure the hygienic environment during the production process and improve the production quality of the towel, the power source for driving the push rod is selected as the cylinder 71, which can achieve rapid reciprocating motion, quickly follow the work even when the towel conveying speed is relatively fast, and there is no pollution.

[0044] As Figure 2 shown, the high-position conveying device 2 is installed on the mounting rack 1 through a high-position mounting component, and the low-position conveying device 3 is installed on the mounting rack 1 through a low-position mounting component;

[0045] The low-position mounting component includes a low-position cross frame 11 arranged on the upper side of the middle part of the mounting rack 1 and at least two low-position vertical plates 12 arranged on the side of the mounting rack 1 away from the high-position conveying device 2. At least two transverse guide grooves corresponding to the positions of the low-position vertical plates 12 are formed on the side surface of the low-position cross frame 11, and longitudinal guide grooves corresponding to the positions of the transverse guide grooves are formed on the low-position vertical plates 12;

[0046] The high-position mounting component includes a high-position cross frame 13 arranged on the upper side of the low-position cross frame 11 and fixedly connected to the low-position cross frame 11, and at least two high-position vertical plates 14 arranged on the side of the mounting rack 1 away from the low-position conveying device 3. At least two transverse guide grooves corresponding to the positions of the high-position vertical plates 14 are formed on the side surface of the high-position cross frame 13, and longitudinal guide grooves corresponding to the positions of the transverse guide grooves are formed on the high-position vertical plates 14.

[0047] By correspondingly setting different low-position mounting components and high-position mounting components, the difference in height is realized, so that when the towel is conveyed to the folding interval, it is in a state where the upper and lower heights are uneven, and the towel located on the low-position conveying device 3 can be located below the limiting plate 61, so as to effectively fold when the push rod is pushed out, and the folding effect is good. The transverse guide grooves arranged on the low-position cross frame 11 and the high-position cross frame 13 play a role in guiding installation and upper and lower limiting. The transverse guide grooves provide an installation basis and a convenient installation environment for the transmission roller assembly 5, and can be finely adjusted to adapt to different situations; the longitudinal guide grooves of the low-position vertical plates 12 and the high-position vertical plates 14 play a role in laterally limiting the transmission roller assembly 5, and cooperate with the transverse guide grooves to realize multi-directional limiting, ensuring the installation stability of the transmission roller assembly 5, thereby ensuring production safety and production efficiency.

[0048] The low vertical plate 12 and the high vertical plate 14 have the same structure, and the longitudinal guide grooves of the low vertical plate 12 and the high vertical plate 14 have a length equal to the sum of the heights of the high horizontal frame 13 and the low horizontal frame 11.

[0049] To reduce production costs, the structures of the high vertical plate 14 and the low vertical plate 12 are set to be the same, and the longitudinal guide grooves for limiting are raised to the sum of the heights of the two horizontal frames, enabling the limiting effect to be achieved at each installation position, further improving the installation convenience, and also providing a good installation foundation for the vertical frame 8.

[0050] As Figure 3 shown, the drive roller assembly 5 includes a driving roller 51 connected to the power output end of the power source 4, driven rollers 52 located at both ends of the mounting frame 1, and a tensioning roller 53 for adjusting the tension of the conveyor belt 6;

[0051] On both sides of one end of the mounting frame 1 close to the power source 4, there are feeding horizontal frames 15. At least two transverse guide grooves are provided on the feeding horizontal frames 15. Both ends of the driving roller 51 are rotatably connected to the bottoms of the feeding horizontal frames 15 on both sides, and the driven rollers 52 and the tensioning roller 53 are respectively rotatably installed in the two transverse guide grooves of the feeding horizontal frames 15.

[0052] By setting the tensioning roller 53, the tension of the conveyor belt can be well adjusted, and the two feeding horizontal frames 15 are used to provide an installation foundation for the drive roller assembly 5, improving the installation convenience. Moreover, the high - level conveyor device 2 and the low - level conveyor device 3 share the same driving roller 51, tensioning roller 53, and one driven roller 52 on the side close to the driving roller 51, making their actions unified, enabling synchronous operation and stop, and ensuring the quality and smoothness of the folding work.

[0053] The low horizontal frame 11, the high horizontal frame 13, and the feeding horizontal frame 15 have the same structure.

[0054] Setting the structures of the three horizontal frames to be the same can reduce production costs and can provide a stable installation foundation for the corresponding components.

[0055] As Figure 4 shown, the high horizontal frame 13 further includes at least one limiting hole, and the output end of the cylinder 71 passes through the limiting hole and is connected to the transverse push rod 72.

[0056] The structure of the limiting hole is the same as that of the transverse guide groove, which is more convenient during production. It is only necessary to firmly fix the cylinder 71 end. Through the setting of the limiting hole, the up - and - down direction deviation of the output end of the cylinder 71 can be avoided, and the collision between the transverse push rod 72 and the limiting plate 61 can be avoided, preventing equipment damage and affecting the towel folding quality.

[0057] As Figure 4As shown in the figure, a guide seat 73 corresponding to the position of the limit hole is arranged on one side of the high-position horizontal frame 13 close to the cylinder 71. The guide seat 73 is fixedly installed on the side surface of the high-position horizontal frame 13. The output end of the cylinder 71 penetrates through the guide seat 73 and is slidably connected to the guide seat 73.

[0058] By installing the guide seat 73, the linear pushing and retraction of the output end of the cylinder 71 can be well realized, avoiding the up, down, left and right offset of the output end of the cylinder 71, and ensuring the quality of towel folding.

[0059] As Figure 1 shown in the figure, it further includes a control host, an article detector 62 installed at the lower end of the vertical frame 8, and a time relay installed between the control host and the cylinder 71. The control host is respectively connected to the time relay and the article detector 62 through signal transmission lines. The time relay is connected to the cylinder 71 through a signal transmission line.

[0060] In order to further realize automated production, the article detector 62 can detect whether there are towels conveyed to the folding area on the conveyor belt 6. The folding area is the working area of the limit plate 61 and the horizontal push rod 72. Through the feedback of the article detector 62, the control host sends a signal to control the cylinder 71 to push, driving the horizontal push rod 72 to extend. Among them, the time relay adjusts different set times according to the running speed of the conveyor belt 6 to ensure that the push rod is pushed out after the towel completely enters the working area to realize towel folding, ensuring the folding efficiency and folding quality.

[0061] In this specification, each embodiment is described in a progressive manner. The key points of each embodiment are the differences from other embodiments. The same and similar parts among the embodiments can be referred to each other.
