Description

Technical Field

[0001] This utility model relates to the field of paper tube processing technology, and in particular to an automatic paper tube cutting machine. Background Technology

[0002] Paper tubes, also known as paper cylinders or cardboard tubes, are tubular objects made from paper or cardboard. They are widely used in many industries, including chemical fibers, films, printing, papermaking, metallurgy, food, transportation and postal services, automobile manufacturing, textiles, packaging, health products, and art supplies. During the paper tube processing, a paper tube cutter is used to cut long paper tubes into shorter segments to meet specific usage requirements.

[0003] Paper tube cutters use rotating blades to cut long paper tubes. However, since the blade position is fixed, the entire blade holder structure needs to be replaced when the length of the cut short paper tubes needs to be adjusted, which is time-consuming and labor-intensive, resulting in poor flexibility of the paper tube cutter. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing paper tube cutters require replacing the entire blade holder structure when the length of the cut short paper tubes needs to be adjusted, which is time-consuming and labor-intensive, resulting in poor flexibility. Therefore, an automatic paper tube cutter is proposed.

[0005] To achieve the above objectives, the present invention employs the following technology: an automatic paper tube cutting machine, comprising a frame, a sleeve for tube fitting is provided on the frame via a support plate, a transmission gear is provided at one end of the sleeve, a drive assembly is provided on the support plate, a knife holder is provided on the support plate at a position behind the sleeve, a cutting assembly is provided on the knife holder via a knife bar, the drive assembly drives the knife bar on the knife holder to rotate while simultaneously driving the sleeve to rotate, and a material unloading assembly is provided on the frame.

[0006] As a further description of the above technical solution: the cutting assembly includes a first mounting base and a second mounting base, both of which are provided with blades, and the first mounting base and the second mounting base are connected by connecting bolts to form a cylindrical structure.

[0007] As a further description of the above technical solution: both the first mounting base and the second mounting base are provided with positioning blocks, and the tool bar is provided with positioning holes that cooperate with the positioning blocks. The number of positioning holes is several and they are arranged at equal intervals along the length direction of the tool bar.

[0008] As a further description of the above technical solution: the first mounting base is provided with a tenon, and the second mounting base is provided with a mortise that mates with the tenon.

[0009] As a further description of the above technical solution: the unloading assembly includes a cylinder fixed to the frame by a fixing bracket, a slide is fixedly connected to the output end of the cylinder, and a clamping plate is provided on the top of the slide.

[0010] As a further description of the above technical solution: the frame is provided with a guide rail, and the slide is provided with a connecting seat that cooperates with the guide rail.

[0011] As a further description of the above technical solution: a discharge port is provided on the support plate at a position in the sliding direction.

[0012] As a further description of the above technical solution: the tool holder is hinged to the support plate, and a telescopic cylinder is provided on the frame, with the output end of the telescopic cylinder hinged to the tool holder.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. The position of the cutting blade assembly can be precisely adjusted by the several positioning holes evenly spaced on the blade holder. When it is necessary to adjust the length of the short paper tube, simply find the corresponding positioning hole and then install the cutting blade assembly according to the positioning hole.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-3 This embodiment provides an automatic paper tube cutting machine, including a frame 1. A sleeve 3 for fitting a tube 11 is provided on the frame 1 via a support plate 2. A transmission gear 4 is provided at one end of the sleeve 3. A drive assembly 5 is provided on the support plate 2. A knife holder 6 is provided on the support plate 2 at a position behind the sleeve 3. A cutting knife assembly 8 is provided on the knife holder 6 via a knife bar 7. The drive assembly 5 drives the knife bar 7 on the knife holder 6 to rotate while simultaneously driving the sleeve 3 to rotate. A discharge assembly 9 is provided on the frame 1.

[0023] In this utility model, the paper tube cutter is placed and fixed by the frame 1. The paper tube body 11 to be cut is manually put into the sleeve 3 installed between the support plates 2. The position of the knife holder 6 is adjusted so that the cutting component 8 on the knife bar 7 contacts the tube body 11 on the sleeve 3. Then the drive component 5 on the support plate 2 drives the cutting component 8 on the knife bar 7 to rotate, and at the same time drives the tube body 11 on the sleeve 3 to rotate. Thus, the cutting component 8 cuts the tube body 11 on the sleeve 3 into segments. After the tube body 11 is cut, the paper tube on the sleeve 3 is unloaded by the unloading component 9.

[0024] It should be noted that the drive assembly 5 includes a motor mounted on the frame 1 and a drive shaft passing through the support plate 2. The motor drives the drive shaft to rotate via a first drive belt, and there is a second drive belt between the drive shaft and the cutter bar 7, which can drive the cutter bar 7 to rotate, further driving the rotation of the cutter assembly 8 on the cutter bar 7 to realize the paper tube cutting operation.

[0025] Specifically, such as Figure 2 and Figure 3As shown, the cutter assembly 8 includes a first mounting base 81 and a second mounting base 82. Both the first mounting base 81 and the second mounting base 82 are provided with blades 83. The first mounting base 81 and the second mounting base 82 are connected by connecting bolts 84 to form a cylindrical structure.

[0026] During the installation of the cutter assembly 8, the first mounting base 81 and the second mounting base 82 are fastened onto the cutter bar 7, forming a cylindrical structure sleeved on the cutter bar 7. Then, the first mounting base 81 and the second mounting base 82 are joined and fixed together using the connecting bolt 84, so that the blades 83 on the first mounting base 81 and the second mounting base 82 form an integral circular cutter, thereby ensuring that the cutter can perform the cutting work of paper tubes.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, both the first mounting base 81 and the second mounting base 82 are provided with positioning blocks 85, and the tool bar 7 is provided with positioning holes 71 that cooperate with the positioning blocks 85. The number of positioning holes 71 is several and they are arranged at equal intervals along the length direction of the tool bar 7.

[0028] Among them, several positioning holes 71 divide the length of the knife bar 7 at equal intervals. When installing the cutter assembly 8, the position of the cutter assembly 8 can be adjusted according to the length of the paper tube after cutting. Just find the position of the positioning hole 71 on the knife bar 7 according to the length, and then align the positioning block 85 on the first mounting base 81 and the second mounting base 82 with the corresponding positioning hole 71 to achieve precise installation of the cutter assembly 8, making the paper tube cutter more flexible.

[0029] It should be noted that the first mounting base 81 is provided with a tenon 86, and the second mounting base 82 is provided with a mortise 87 that mates with the tenon 86. When the first mounting base 81 and the second mounting base 82 are installed, the tenon 86 and the mortise 87 can be used to fix the first mounting base 81 and the second mounting base 82 in advance, which facilitates the subsequent connection of the connecting bolts 84, and makes the installation of the cutter assembly 8 easier and more convenient.

[0030] Specifically, such as Figure 1 As shown, the unloading assembly 9 includes a cylinder 92 fixed to the frame 1 by a fixing bracket 91. A slide 93 is fixedly connected to the output end of the cylinder 92, and a clamping plate 94 is provided on the top of the slide 93. A guide rail 10 is provided on the frame 1, and a connecting seat 95 that cooperates with the guide rail 10 is provided on the slide 93. An unloading port is provided on the support plate 2 at a position in the moving direction of the slide 93.

[0031] The clamping plate 94 is arc-shaped. After the paper tube to be cut is inserted into the sleeve 3, the clamping plate 94 clamps one end of the paper tube. After the paper tube is cut, the cylinder 92 on the fixing frame 91 is activated. The cylinder 92 pushes the slide 93 to move on the guide rail 10. As the slide 93 moves, it drives the clamping plate 94 to move. Then the clamping plate 94 clamps the paper tube and moves, pushing the paper tube out of the sleeve 3 and falling from the discharge port to realize the unloading work.

[0032] Specifically, such as Figure 1 As shown, the tool holder 6 is hinged to the support plate 2, and a telescopic cylinder is provided on the frame 1, with the output end of the telescopic cylinder hinged to the tool holder 6.

[0033] Before the paper tube is cut, the knife holder 6 is tilted. At this time, the cutting assembly 8 on the knife bar 7 is close to the sleeve 3. When the paper tube is put on the sleeve 3 and needs to be cut, the telescopic cylinder is activated and extended. The telescopic rod pushes the knife holder 6 to rotate, so that the front end of the knife holder 6 rotates downward, thereby making the cutting assembly 8 on the knife bar 7 contact the paper tube on the sleeve 3, and thus enabling the cutting assembly 8 to cut the paper tube.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
