[0035] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0036] Example:

[0037] like Figure 1 , 2 As shown, the utility model provides a non-woven fabric roll feeding device, which is used to be installed on a seedling container forming machine to feed non-woven fabrics, including a frame 101, on which at least two groups of rotatable non-woven fabric rolls 201 are arranged, and on which at least two groups of mounting shafts 102 are arranged, and the non-woven fabric rolls 201 are rotatably sleeved on the mounting shafts 102, and a limiting assembly is also arranged on the mounting shafts 102. The limiting assembly includes a limiting ring 104, which is slidably sleeved on the mounting shaft 102, and the mounting shaft 102 has multiple groups of fixing holes 103 evenly distributed along its axis, and the limiting ring 104 is provided with a screwed limiting pin 105, and the limiting pin 105 is inserted through one of the groups of fixing holes 103.

[0038] When the device is in use, the rolled non-woven fabric roll 201 is sleeved on the installation shaft 102, and the position of the limit ring 104 is fixed by inserting the limit pin 105 into one of the fixed holes 103, so that the non-woven fabric roll 201 can be limited to prevent the non-woven fabric roll 201 from sliding on the installation shaft 102, and by setting multiple groups of fixed holes 103 at different positions, the non-woven fabric rolls 201 of different widths can be limited, thereby improving the application range of the device. It is known that a winding drum is set at the center of the non-woven fabric roll 201, and the friction between the winding drum of the non-woven fabric roll 201 and the installation shaft 102 makes the non-woven fabric roll 201 encounter a certain resistance when rotating, so that the non-woven fabric roll 201 can be easily tensioned.

[0039] like Figure 3 , 4 As shown, in this embodiment, a tensioning mechanism is provided on the frame 101, wherein a group of non-woven fabric rolls 201 are tensioned by the tensioning mechanism and connected to the processing end of the seedling container forming machine, the tensioning mechanism includes a mounting frame 205 arranged on the frame 101, a slider 203 is provided in a sliding card inside the mounting frame 205, a tensioning shaft 202 is rotatably provided on the slider 203, wherein a group of non-woven fabric rolls 201 are wound around the tensioning shaft 202, one end of the tension spring 207 is connected to the slider 203, and the other end is connected to the frame 101.

[0040] After the installation of the non-woven fabric roll 201 is completed, one end of the non-woven fabric roll 201 can be passed around the tensioning shaft 202 and connected to the processing end of the seedling container forming machine. Through the processing of the seedling container forming machine, one end of the non-woven fabric roll 201 is pulled, so that under the action of the friction between the non-woven fabric roll 201 and the installation shaft 102 and its own gravity, the tensioning shaft 202 slides along the installation frame 205 and the tension spring 207 is stretched. When a single roll of the non-woven fabric roll 201 is to be used up, the non-woven fabric roll 201 relaxes to contact the tension applied to the tensioning shaft 202, so that the tension spring 207 is reset and drives the slider 203 to reset.

[0041] like Figure 3 As shown, in this embodiment, a support plate 302 is provided on the frame 101, a group of tensioned non-woven fabric rolls 201 are placed on the support plate 302, and the ends of another group of non-woven fabric rolls 201 are also placed on the support plate 302. Four groups of support rollers 301 are also provided on the frame 101, and every two groups of support rollers 301 form a group of gaps for accommodating the non-woven fabric rolls 201, and the non-woven fabric rolls 201 are arranged in the gaps. After the non-woven fabric rolls 201 are installed, the support plate 302 is used to support the middle section of one group of non-woven fabric rolls 201, and the ends of the other group of non-woven fabric rolls 201 are supported, so that the two groups of non-woven fabric rolls 201 are in an overlapping state, and the group of non-woven fabric rolls 201 in the processing state moves on the support plate 302, and the ends of the other group of non-woven fabric rolls 201 are in a stationary state. Furthermore, the two groups of non-woven fabric rolls 201 are limited by four groups of supporting rollers 301 to prevent the non-woven fabric rolls 201 from being separated from the supporting plate 302 .

[0042] like Figure 3 , 4 As shown, in this embodiment, a hot melt mechanism is provided on the frame 101, and the two groups of non-woven fabric rolls 201 on the support plate 302 are heated and bonded by the hot melt mechanism when the tensioning mechanism is relaxed. The hot melt mechanism includes a telescopic rod 303, one end of which is fixedly arranged on the frame 101, and a heating block 304 is arranged at the end of the telescopic rod 303, and the heating block 304 is located on the opposite side of the support plate 302. A control switch 206 is provided on the mounting frame 205, and the control switch 206 controls the extension of the telescopic rod 303 and controls the heating block 304 to heat when triggered, and a contact block 204 is provided on the slider 203 on the opposite side of the control switch 206.

[0043] When a group of non-woven fabric rolls 201 in processing are used up and the tension shaft 202 loses external force and resets under the action of the tension spring 207, the slider 203 moves downward and triggers the control switch 206 through the contact block 204, thereby controlling the extension of the telescopic rod 303 and controlling the heating block 304 to heat. After the heating block 304 moves to the support plate 302, it heats the overlapping position of the two groups of non-woven fabric rolls 201. Since the non-woven fabric rolls 201 are thermoplastic, they will melt after being heated to a certain degree and will quickly solidify after cooling, and then bond together. After the heating block 304 presses the two groups of non-woven fabric rolls 201 to heat them, the end of the used group of non-woven fabric rolls 201 is fixed by the heating block 304, so that the non-woven fabric rolls 201 can be tensioned again, so that the contact block 204 is separated from the control switch 206, and the telescopic rod 303 can be controlled to retract and stop the heating block 304 from heating, and the unused group of non-woven fabric rolls 201 can be pulled by the previous group of non-woven fabric rolls 201 and put into use, so that the non-woven fabric rolls 201 do not need to be manually replaced after stopping. The telescopic control of the telescopic rod 303 and the heating control of the heating block 304 are common technical means, which will not be repeated here.

[0044] like Figure 1 , 3 As shown, a protection frame 305 is provided on the frame 101, and the heating block 304 is provided in the protection frame 305. The heating block 304 is shielded by the protection frame 305 to avoid injury to the staff when the heating block 304 moves downward, thereby improving the safety of the device when in use.

[0045] Specific usage and beneficial effects of the utility model:

[0046] When the device is in use, at least two groups of non-woven fabric rolls 201 are rotatably mounted on the frame 101, and the end of one group of non-woven fabric rolls 201 is pulled out and placed on the support plate 302, then passed through the tensioning shaft 202 and connected to the processing end of the seedling container forming machine, and the non-woven fabric rolls 201 are pulled through the processing end of the seedling container forming machine for processing, and the group of non-woven fabric rolls 201 are tensioned by the tensioning shaft 202 and the tension spring 207 in cooperation with the gravity of the non-woven fabric rolls 201 themselves and the friction of the installation position, and the end of the other group of non-woven fabric rolls 201 is placed on the support plate On 302, when a group of non-woven fabric rolls 201 being processed is used up, the group of non-woven fabric rolls 201 relaxes to make the tension spring 207 contract, driving the slider 203 to slide and triggering the control switch 206 through the contact block 204, so that the two groups of non-woven fabric rolls 201 on the support plate 302 can be heated and bonded by controlling the extension rod 303 and heating the heating block 304, so as to quickly complete the replacement of the non-woven fabric rolls 201, without the need to stop and manually replace the non-woven fabric rolls 201, which effectively reduces the labor intensity of the staff and improves the work efficiency.
