Description

Technical Field

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

[0002] When feeding paper tubes during the operation of the cutting machine, the clamping mechanism needs to be released and the paper tubes pushed by hand by grasping the part of the paper tube that protrudes from the end of the clamping mechanism.

[0003] In order to ensure that the tightening and loosening driving force is transmitted centrally and relatively evenly to the clamping mechanism, the drive structure of the existing clamping mechanism is mostly centered. The power output component of the drive structure is also generally centered. This means that in the feeding operation, the hand must first drive the power output component at the middle position of the clamping mechanism to release the clamping force, and then move to the tail position of the clamping mechanism to grasp and push the paper tube for feeding. Finally, it must move back to the middle position of the clamping mechanism to re-drive and clamp. However, in order to ensure the clamping stability of long paper tubes, the clamping mechanism is generally set to be long. This makes the distance between the middle position and the tail position long. As a result, when the hand repeatedly moves between the middle and tail positions of the clamping mechanism, it needs to make a large swinging movement. The operation is cumbersome and inconvenient, which indirectly reduces the feeding efficiency and cutting efficiency of the paper tube. Utility Model Content

[0004] In view of this, the present invention provides a paper tube clamping mechanism for a paper tube cutting machine to solve the problem of low feeding efficiency and cutting efficiency of paper tubes.

[0005] The technical solution proposed by this utility model is: a paper tube clamping mechanism for a paper tube cutting machine, specifically including: an operating table, two T-shaped brackets are symmetrically welded to the bottom of both ends of the operating table, and two longitudinally sliding long strip clamps are symmetrically installed at the middle position of the top of the operating table in the length direction.

[0006] The two long clamping plates are used to clamp and fix the paper tube to be cut during the cutting process, and two U-shaped sliding frames are symmetrically welded on opposite sides of the two long clamping plates; a drive wheel assembly is rotatably suspended at the center of the operating platform. The drive wheel assembly is composed of a large-diameter drive wheel and a small-diameter gear fixedly fitted to the bottom of the central shaft sleeve of the large-diameter drive wheel. The wheel rim of the large-diameter drive wheel is symmetrically rotatably connected to the two U-shaped sliding frames by two tie rods.

[0007] A horizontally sliding cross brace rack is installed below the operating platform, and the cross brace rack meshes with a small-diameter gear for transmission; a horizontally supporting threaded drive shaft is rotatably suspended below the operating platform, and a small-diameter driven gear is fixedly fitted at the first end of the threaded drive shaft; the threaded drive shaft and the cross brace rack are screwed together through each other; a large-diameter driving gear is rotatably installed at the top of the T-shaped bracket near the small-diameter driven gear, and the large-diameter driving gear meshes with the small-diameter driven gear for transmission.

[0008] Furthermore,

[0009] The operating platform has a long rectangular structure, and two vertical positioning blocks are symmetrically welded on both long sides. The two U-shaped sliding frames are respectively slidably engaged with the top parts of the two vertical positioning blocks on the corresponding sides.

[0010] Furthermore,

[0011] The middle section of the cross brace side shaft of the U-shaped sliding frame is welded downwards with a vertical force transmission shaft, and the first ends of the two tie rods are rotatably connected to the bottom ends of the two vertical force transmission shafts.

[0012] Furthermore,

[0013] A cross brace positioning shaft is welded and hoisted below the operating platform near the threaded drive shaft, and the cross brace rack slides in conjunction with the cross brace positioning shaft.

[0014] Furthermore,

[0015] An L-shaped rocker arm is welded to the first end of the central shaft of the large-diameter drive gear.

[0016] Furthermore,

[0017] An L-shaped sliding frame is slidably installed on the T-shaped bracket at another location. A rectangular rod sleeve is welded to the tail end of the L-shaped sliding frame. The rectangular rod sleeve slides in conjunction with the vertical support rod of the T-shaped bracket, and a foot plate is swung on the bottom side of the vertical support rod.

[0018] A cutting motor is fixedly installed at the top of the L-shaped sliding frame. A cutting wheel is fixedly fitted at the front end of the cutting motor shaft. When the cutting wheel slides upward, it comes into contact with the paper tube to cut the paper tube.

[0019] Furthermore,

[0020] The first end of the footplate is rotatably connected to the rectangular sleeve by a connecting rod.

[0021] The paper tube clamping mechanism of the paper tube cutting machine provided by this utility model has the following beneficial effects:

[0022] 1. The large-diameter drive gear is the power output component that drives the two long clamping plates to tighten or loosen. The large-diameter drive gear is located near the tail ends of the two long clamping plates. This allows the hand to directly operate the large-diameter drive gear in a small space at the tail ends of the two long clamping plates to tighten or loosen the two long clamping plates and push the paper tube to complete the entire feeding operation. Compared with the existing technology where the power output component is centrally located on the two long clamping plates, this eliminates the trouble of having to perform repeated large-distance and large-amplitude swinging and transfer movements between the middle and tail ends of the two long clamping plates to complete the feeding operation. This helps to indirectly improve the feeding and cutting efficiency of paper tubes.

[0023] Second, the foot pedal is set close to the ground, and can be directly driven by foot pressure. This allows the cutting motor and cutting wheel to be driven up and down by foot force. The up and down cutting operation of this utility model is driven by foot force, which avoids the occupation of the hands compared with the traditional cutting machine driven by hand operation, making the operation more labor-saving, convenient and efficient.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this 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, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0040] For ease of description, the two sides where the two I-beam brackets 101 are located are designated as the front and rear sides.

[0041] Please refer to Figures 1 to 5 ; Example

[0042] This utility model proposes a paper tube clamping mechanism for a paper tube cutting machine, including: an operating table 1, two T-shaped brackets 101 symmetrically welded to the bottom of both ends of the operating table 1, and two longitudinally sliding long strip clamps 4 symmetrically installed at the middle position of the top of the operating table 1 in the length direction.

[0043] Two long strip clamps 4 are used to clamp and fix the paper tube 2 to be cut during the cutting process, and two U-shaped sliding frames 401 are symmetrically welded on opposite sides of the two long strip clamps 4; a drive wheel set 5 is rotatably suspended at the center of the operating platform 1. The drive wheel set 5 is composed of a large diameter drive wheel and a small diameter gear fixedly fitted to the bottom of the central shaft sleeve of the large diameter drive wheel. Two tie rods 501 are symmetrically rotatably connected between the wheel rim of the large diameter drive wheel and the two U-shaped sliding frames 401.

[0044] The large-diameter drive wheel, two tie rods 501 and two U-shaped sliding frames 401 are connected to form two crank-slider mechanisms. Through these two mechanisms, the large-diameter drive wheel is twisted and driven, which can drive the two long strip clamps 4 to slide towards each other to tighten or loosen the paper tube 2.

[0045] A transversely sliding rack 108 is installed below the operating platform 1, and the transverse rack 108 meshes with a small-diameter gear for transmission; a transversely supporting threaded drive shaft 107 is rotatably suspended below the operating platform 1, and a small-diameter driven gear 1071 is fixedly fitted at the head end of the threaded drive shaft 107; the threaded drive shaft 107 and the transverse rack 108 are screwed together through; a large-diameter driving gear 6 is rotatably installed at the top end of the T-shaped bracket 101 near the small-diameter driven gear 1071, and the large-diameter driving gear 6 meshes with the small-diameter driven gear 1071 for transmission.

[0046] Through a small-diameter gear, the cross brace rack 108 slides laterally back and forth, which can mesh with and drive the large-diameter drive wheel and the drive wheel assembly 5 to rotate in both directions; the threaded drive shaft 107 can rotate in both directions to propel the cross brace rack 108 to slide laterally back and forth; through a small-diameter driven gear 1071, the large-diameter drive gear 6 can rotate and mesh with and drive the threaded drive shaft 107 to rotate in both directions, providing a tension driving force for the two long strip clamps 4 to slide in opposite directions;

[0047] When feeding the paper tube 2, the two long clamps 4 should be loosened first, and then the paper tube 2 should be pushed forward by grasping the exposed end of the two long clamps 4 with your hands. Finally, the two long clamps 4 should be clamped again.

[0048] The large-diameter drive gear 6 is a power output component that drives the two long clamping plates 4 to tighten or loosen. The large-diameter drive gear 6 is set close to the tail end of the two long clamping plates 4. This allows the hand to operate the large-diameter drive gear 6 directly in the small space at the tail end of the two long clamping plates 4 to tighten or loosen the two long clamping plates 4 and push the paper tube 2 to complete the entire feeding operation. Compared with the existing technology where the power output component is set in the middle on the two long clamping plates 4, it eliminates the trouble of having to perform repeated large-distance and large-amplitude swinging and transfer movements between the middle and tail ends of the two long clamping plates 4 to complete the feeding operation. This helps to indirectly improve the feeding and cutting efficiency of the paper tube 2.

[0049] The large-diameter driving gear 6 has a much larger diameter than the small-diameter driven gear 1071, and also has a much larger number of teeth. This makes the transmission ratio between the large-diameter driving gear 6 and the small-diameter driven gear 1071 smaller. The large-diameter driving gear 6 has a significant speed-up effect on the small-diameter driven gear 1071. With the support of this speed-up effect, the rotational speed of the threaded drive shaft 107 and the relative sliding speed of the two long strip clamps 4 will be significantly increased. This helps to improve the tensioning efficiency of the paper tube 2 and further indirectly improves the feeding and cutting efficiency of the paper tube 2.

[0050] Preferred,

[0051] The operating platform 1 has a long rectangular structure, and two vertical positioning blocks 105 are symmetrically welded on both long sides. The two U-shaped sliding frames 401 are respectively connected to the top part of the two vertical positioning blocks 105 on the corresponding side through sliding fit.

[0052] Preferred,

[0053] The middle section of the cross brace side shaft of the U-shaped sliding frame 401 is welded downwards with a vertical force transmission shaft 4011, and the first ends of the two tie rods 501 are rotatably connected to the bottom ends of the two vertical force transmission shafts 4011.

[0054] Preferred,

[0055] A cross brace positioning shaft 106 is welded and hoisted below the operating platform 1 near the threaded drive shaft 107, and the cross brace rack 108 slides in conjunction with the cross brace positioning shaft 106.

[0056] Preferred,

[0057] An L-shaped rocker arm 601 is welded to the first end of the central shaft of the large-diameter drive gear 6.

[0058] Based on Example 1, Example 2:

[0059] An L-shaped sliding frame 104 is slidably installed on another T-shaped bracket 101. A rectangular rod sleeve is welded to the tail end of the L-shaped sliding frame 104. The rectangular rod sleeve slides in cooperation with the vertical support rod of the T-shaped bracket 101, and a foot plate 102 is swung on the bottom side of the vertical support rod.

[0060] A cutting motor 3 is fixedly installed at the top of the L-shaped sliding frame 104, and a cutting wheel 301 is fixedly fitted at the first end of the shaft of the cutting motor 3. The cutting motor 3 is used to drive the cutting wheel 301 to cut the paper tube 2 at high speed. When the cutting wheel 301 slides upward, it abuts against the paper tube 2 to achieve the cutting of the paper tube 2.

[0061] Preferred,

[0062] A connecting rod 103l is rotatably connected between the first end of the footplate 102 and the rectangular sleeve;

[0063] The connecting rod 103, the foot plate 102, and the L-shaped sliding frame 104 are connected to form a crank-slider mechanism. Through this mechanism, the foot plate 102 can be rotated up and down to drive the L-shaped sliding frame 104, the cutting motor 3, and the cutting wheel 301 to slide back and forth, cutting the paper tube 2. The foot plate 102 is set close to the ground and can be directly driven by foot pressure. This allows the cutting motor 3 and the cutting wheel 301 to be driven up and down by foot force. The up and down cutting operation of this utility model is driven by foot force, which avoids the occupation of hands compared with the traditional cutting machine driven by hand operation, making the operation more labor-saving, convenient, and efficient.

[0064] The working principle of this embodiment:

[0065] Two long clamping plates 4 are used to clamp and fix the paper tube 2 to be cut during the cutting process. The large-diameter drive wheel, two tie rods 501 and two U-shaped sliding frames 401 are connected to form two crank-slider mechanisms. Through these two mechanisms, the large-diameter drive wheel is torsionally driven, which can drive the two long clamping plates 4 to slide towards each other to tighten or loosen the paper tube 2. Through the small-diameter gear, the cross brace rack 108 slides laterally back and forth, which can mesh to drive the large-diameter drive wheel and the drive wheel group 5 to rotate in both directions. The threaded drive shaft 107 can rotate in both directions to drive the cross brace rack 108 to slide laterally back and forth. Through the small-diameter driven gear 1071, the large-diameter drive gear 6 can rotate to mesh with the threaded drive shaft 107 to rotate in both directions, providing the tightening and loosening driving force for the two long clamping plates 4 to slide towards each other.

[0066] The cutting motor 3 is used to drive the cutting wheel 301 at high speed to cut the paper tube 2. The connecting rod 103, the foot plate 102, and the L-shaped sliding frame 104 are connected to form a crank-slider mechanism. Through this mechanism, the foot plate 102 can be rotated up and down to drive the L-shaped sliding frame 104, the cutting motor 3, and the cutting wheel 301 to slide back and forth to cut the paper tube 2. The foot plate 102 is set close to the ground and can be directly driven by foot pressure.

[0067] When cutting a longer paper tube 2 to the required length, the paper tube 2 needs to be fed. When feeding the paper tube 2, the two long clamps 4 need to be loosened first, and then the paper tube 2 is pushed forward by grasping the exposed tail end of the two long clamps 4 with the hand. Finally, the two long clamps 4 are clamped again.
