Description

Technical Field

[0001] This utility model relates to the field of paper tube cutting technology, and in particular to a moving cutting structure for a paper tube cutting machine. Background Technology

[0002] In a typical paper tube cutting machine, the cutting blade is mounted between two rotating and fixed structures. To prevent unstable cutting due to excessively long paper tubes, a pressure roller is usually added near the cutting blade to provide a third fulcrum and ensure smooth cutting.

[0003] However, this design limits the cutting blade to a limited distance between one end of the paper tube and the pressure roller. Since this distance cannot be too large, otherwise it will affect the cutting effect, the cutting length of the paper tube is significantly restricted. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To address the aforementioned problems, this utility model provides the following technical solution:

[0006] A movable cutting structure for a paper tube cutting machine includes a support frame, a first pressure roller group, and a second pressure roller group. The support frame is movably mounted on a slide rod. The first pressure roller group is mounted on the top plate of the support frame via a cylinder mechanism. The second pressure roller group is mounted on the bottom plate of the support frame. Both the first and second pressure roller groups are symmetrically equipped with rollers.

[0007] The cutter head is mounted on the bridge plate of the support frame via a cylinder mechanism. The cutter head is located between the symmetrical rollers of the first pressure roller group or the second pressure roller group. Driven by the cylinder mechanism, the outer end of the cutter head gradually approaches the paper tube and finally extends into the inner cavity of the paper tube to complete the cutting action.

[0008] Preferably, the cutter head is located at the center between the symmetrical rollers of the first pressure roller group or the second pressure roller group, and the cutter head is close to the bridging plate.

[0009] Preferably, the cutter head is located at the center between the rollers on the same side of the first pressure roller group and the second pressure roller group.

[0010] Preferably, the first pressure roller assembly includes a first support, a first shaft, and a first roller, and the second pressure roller assembly includes a second support, a second shaft, and a second roller, and the first pressure roller assembly and the second pressure roller assembly are identical.

[0011] Preferably, the first bracket is symmetrically provided with two sets of first shafts, and each first shaft is provided with a first roller.

[0012] Preferably, the ratio of the diameter of the transverse circle of the first roller to the length of the first roller is greater than 1:2.

[0013] Preferably, the sliding rod has graduations at equal intervals.

[0014] Preferably, the first bracket is provided with a limiting rod, which is sleeved in the limiting hole of the top plate. The first bracket is set in the first adapter groove of the top plate through a cylinder mechanism, and the second bracket is set on the bottom plate.

[0015] Preferably, the bottom of the base plate is provided with symmetrical sliders, which are sleeved on the sliding rod, and the sliders are threaded with limiting handles.

[0016] Preferably, the bridging plate between the bottom plate and the top plate has a second adapter groove, and the cylinder mechanism on the cutter head is mounted on the bridging plate through the second adapter groove.

[0017] The beneficial effects of this invention are as follows: the cutter head is installed between the symmetrical rollers of the first and second pressure roller groups. During the cutting process, one end of the paper tube is supported by a rotating fixed structure, and the other end is supported by the rollers of the pressure roller group, with the support point close to the cutting position of the cutter head. When it is necessary to adjust the cutting position, the entire support frame can be moved by the slide rod, causing the cutter head and the pressure roller group to shift as a whole, thereby greatly expanding the cuttable range.

[0018] This structure, through the synergistic effect of symmetrically arranged pressure rollers and adjustable cutter heads, ensures stability during cutting and effectively overcomes the limitations of traditional single pressure roller structures on cutting length. Attached Figure Description

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Example

[0033] Reference Figures 1 to 6 This embodiment of the present invention provides a movable cutting structure for a paper tube cutting machine, including a support frame 100, a first pressure roller group 200 and a second pressure roller group 300. The support frame 100 is movably mounted on a slide rod 600. The first pressure roller group 200 is mounted on the top plate 104 of the support frame 100 via a cylinder mechanism 400. The second pressure roller group 300 is mounted on the bottom plate 103 of the support frame 100. Both the first pressure roller group 200 and the second pressure roller group 300 are symmetrically provided with rollers.

[0034] The cutter head 401 is mounted on the bridge plate 105 of the support frame 100 via the cylinder mechanism 400. The cutter head 401 is located between the symmetrical rollers of the first pressure roller group 200 or the second pressure roller group 300. Driven by the cylinder mechanism 400, the outer end of the cutter head 401 gradually approaches the paper tube 500 and finally extends into the inner cavity of the paper tube 500 to complete the cutting action.

[0035] Specifically, the support frame 100 provides an overall support frame, and its bottom is equipped with a sliding mechanism that can move along the slide rod 600 to achieve lateral adjustment of the cutting station; the first pressure roller group 200 and the second pressure roller group 300

[0036] The first pressure roller assembly 200 is mounted on the top plate 104 of the support frame 100 via a cylinder mechanism 400, and is used to press the paper tube 500 from above; the second pressure roller assembly 300 is fixed to the bottom plate 103 of the support frame 100, and is used to support the paper tube 500 from below, and rollers are symmetrically arranged with the first pressure roller assembly 200 to form a clamping and limiting structure for the paper tube 500; one cylinder mechanism 400 is used to drive the first pressure roller assembly 200 to move up and down to adjust the pressing force, and another cylinder mechanism 400 is used to drive the cutter head 401 to perform the cutting action; the cutter head 401 is mounted on the bridge plate 105 of the support frame 100 via the cylinder mechanism 400, and is used to cut the paper tube 500;

[0037] Its position is between the symmetrical rollers of the first pressure roller group 200 or the second pressure roller group 300. Under the drive of the cylinder, the outer end of the cutter head 401 first approaches the paper tube 500 radially, and then extends axially into the inner cavity of the paper tube 500 to complete the cutting.

[0038] It is worth mentioning that the cutter head 401 is installed between the symmetrical rollers of the pressure roller group. When the cutter head 401 cuts the paper tube 500, the paper tube 500 has both a rotating and fixed structure and the roller support of the pressure roller group. The rollers are close to the position where the cutter head 401 cuts the paper tube 500. When the paper tube 500 needs to adjust the cutting position, the cutter head 401 and the pressure roller group can be moved as a whole through the support frame 100. The movement position is greatly improved. Through the synergistic effect of the symmetrical pressure roller group and the adjustable cutter head 401, the stability of the paper tube is ensured during cutting, and the limitation of the cutting length by the traditional single pressure roller structure is broken.

[0039] Furthermore, the cutter head 401 is located in the center between the symmetrical rollers of the first pressure roller group 200 or the second pressure roller group 300, and the cutter head 401 is close to the bridge plate 105. The cutter head 401 is located in the center between the rollers on the same side of the first pressure roller group 200 and the second pressure roller group 300. When the cutter head 401 is pushed forward for cutting by the cylinder mechanism 400, it is exactly located in the middle of the first pressure roller group 200 and the second pressure roller group 300. This means that the position where the cutter head 401 cuts the paper tube 500 is located at the stress intersection of the two pressure roller groups. This cutter head further ensures the stability of the paper tube during cutting.

[0040] Furthermore, the first pressure roller group 200 includes a first support 201, a first shaft 202, and a first roller 203, and the second pressure roller group 300 includes a second support 301, a second shaft 302, and a second roller 303. The first pressure roller group 200 and the second pressure roller group 300 are completely identical and mirror-symmetrical. The first support 201 is symmetrically provided with two sets of first shafts 202, and each first shaft 202 is provided with a first roller 203. The rollers correspond to the first rollers 203 of the first pressure roller group 200 and the second rollers 303 of the second pressure roller group 300. The second rollers 303 are sleeved on the second shafts 302, and the second support 301 is symmetrically arranged in pairs on the second support 301.

[0041] Furthermore, the ratio of the diameter of the cross-section of the first roller 203 to the length of the first roller 203 is greater than 1:2. The above-mentioned method of setting the cutter head 401 between the rollers to form four fulcrums during the cutting process ensures the stability of the paper tube during cutting. The measure of making the ratio of the diameter of the cross-section of the first roller 203 to the length of the first roller 203 greater than 1:2 extends the length of the roller and makes the "fulcrum" near the cutter head 401 form a support surface, further ensuring the stability of the paper tube during cutting.

[0042] Furthermore, the slide bar 600 has equally spaced scales 600a, which facilitates the movement of the support frame 100 to the corresponding scale 600a position, thereby making it easier for the cutter head 401 to move to the corresponding cutting position.

[0043] Furthermore, to facilitate the installation of the first pressure roller group 200, the second pressure roller group 300, and the cutter head 401 on the support frame 100, and the installation of the support frame 100 on the slide rod 600, the first bracket 201 is provided with a limiting rod 204, which is sleeved in the limiting hole 104b of the top plate 104. The first bracket 201 is set in the first adapter groove 104a of the top plate 104 through the cylinder mechanism 400. The second bracket 301 is set on the bottom plate 103. The bottom of the bottom plate 103 is provided with symmetrical sliders 101, which are sleeved on the slide rod 600. The sliders 101 are threaded with a limiting handle 102. The bridge plate 105 between the bottom plate 103 and the top plate 104 is provided with a second adapter groove 105a. The cylinder mechanism 400 on the cutter head 401 is set on the bridge plate 105 through the second adapter groove 105a.

[0044] Specifically, the installation structure of the first pressure roller group 200: the first bracket 201 is provided with a limiting rod 204, which is sleeved in the limiting hole 104b of the top plate 104 to constrain the lateral displacement of the pressure roller group. The first bracket 201 is embedded in the first adapter groove 104a of the top plate 104 through the cylinder mechanism 400 to ensure the vertical movement accuracy of the pressing mechanism.

[0045] The installation structure of the second pressure roller group 300: The second bracket 301 is directly fixed on the base plate 103, forming a vertically symmetrical layout with the first pressure roller group 200. The roller spacing is synchronously adjusted through the cooperation of the limiting hole 104b and the limiting rod 204.

[0046] The sliding structure of the support frame 100: The bottom of the base plate 103 is provided with symmetrical sliders 101. The sliders 101 are sleeved on the slide rod 600 and are used to guide the lateral movement of the support frame 100. The sliders 101 are threadedly connected to the limit handle 102. By tightening the limit handle 102, the position of the support frame 100 on the slide rod 600 can be locked.

[0047] The mounting structure of the cutter head 401: The bridge plate 105 has a second adapter groove 105a. The cylinder mechanism 400 of the cutter head 401 is fixed to the bridge plate 105 through the second adapter groove 105a, so that the radial feed trajectory of the cutter head 401 is aligned with the clamping center of the pressure roller group. The longitudinal layout of the second adapter groove 105a allows adjustment of the initial feed position of the cutter head 401.
