Technical Field

[0001] The utility model relates to the technical field of straw production, in particular to a heat-resistant polylactic acid straw cutting machine. Background Art

[0002] A straw is a drinking utensil that is often used in people's daily lives. During its production process, the raw materials are usually heated to a molten state and then plasticized, and then cut to further adjust their shape.

[0003] In the prior art, for example, a heat-resistant polylactic acid straw cutting machine disclosed in publication number CN205651398U cuts the straws with a rotating cutting knife and then sends the cutters into a baffle for limiting.

[0004] In actual use, the above-mentioned device only cuts the straws by repeatedly rotating a single cutting knife, and the feeding state is still maintained during the cutting process, which easily causes the cut part to become spiral. Therefore, the straws should be limited during cutting, or they cannot continue to move, and the efficiency of a single cutting knife is not high. In addition, when using a baffle for collection, it is easy to cause the straws to accumulate, and eventually the discharge port may be blocked, thereby causing cutting problems. Utility Model Content

[0005] (1) Technical problems solved

[0006] The invention solves the problem that the straws continue to move when being cut and the cutting efficiency is low; and solves the problem that the use of baffles to collect straws easily leads to the accumulation of straws, thereby causing the discharge port to be blocked.

[0007] (2) Technical solution

[0008] To achieve the above-mentioned object, the present invention provides the following technical solutions: a heat-resistant polylactic acid straw cutting machine, comprising a first bracket, wherein the first bracket is provided with a circular hole for allowing a pipe to pass through;

[0009] Also included is a cutting structure disposed on the first bracket;

[0010] The cutting structure includes a cutting tube arranged on a first bracket, a connecting tube arranged in the cutting tube, a hydraulic rod fixed to one side of the connecting tube, a knife holder fixed on the hydraulic rod, a cutting knife fixed on the knife holder, a connecting plate fixed on the knife holder, and a limiting block fixed on the connecting plate.

[0011] Preferably, a mounting block is fixedly connected to the cutting tube, and a through hole is opened on the cutting tube.

[0012] Preferably, a hydraulic pipe is provided in the connecting pipe for connecting to an external hydraulic machine to control the extension and retraction of the hydraulic rod.

[0013] Preferably, a square groove is provided on the mounting block, and the connecting plate is slidably connected to the mounting block through the square groove, and a collecting structure is provided on one side of the cutting tube.

[0015] Preferably, a round rod is fixedly connected to the feeding frame, a collecting frame is fixedly connected to the lower side of the feeding frame, and a cover plate is provided on one side of the collecting frame.

[0016] (3) Beneficial effects

[0017] Compared with the existing technology, the utility model provides a heat-resistant polylactic acid straw cutting machine with the following beneficial effects:

[0018] 1. The cutting knife on the knife holder is controlled by the hydraulic rod in the cutting tube, so that the cutting knife can cut the straw accurately. When cutting, the subsequent straws will be blocked, so that the straws cannot move forward, thereby ensuring the accuracy of cutting. In addition, multiple straws can be passed into the cutting tube at the same time, and multiple straws can be cut at the same time, which can ensure cutting efficiency.

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1-2 , which is the first embodiment of the utility model, provides a heat-resistant polylactic acid straw cutting machine, including a first bracket 1, the first bracket 1 has two legs for supporting the ground, and the cutting pipe 21 is fixedly connected to the first bracket 1, and the first bracket 1 has a circular hole for the pipe to pass through;

[0028] It also includes a cutting structure provided on the first bracket 1;

[0029] The cutting structure includes a cutting tube 21 arranged on the first bracket 1, which is a circular cylinder with several through holes 29 and a connecting tube 22, wherein the through holes 29 are used for the passage of the suction pipe, and the connecting tube 22 is used for the passage of the hydraulic pipe 210, the connecting tube 22 arranged in the cutting tube 21, a hydraulic rod 23 fixed on one side of the connecting tube 22, the hydraulic rod 23 is directly connected to the hydraulic pipe 210, and the hydraulic pipe 210 is connected to an external hydraulic press, and the extension and contraction of the hydraulic rod 23 can be directly controlled by the external hydraulic press, a knife holder 24 fixed on the hydraulic rod 23, the knife holder 24 is fixedly connected by a connecting plate 26 and a limit block 27, a cutting knife 25 fixed on the knife holder 24, the cutting edge of the cutting knife 25 is facing the suction pipe in the through hole 29, a connecting plate 26 fixed on the knife holder 24, and a limit block 27 fixed on the connecting plate 26, the limit block 27 is used to limit the knife holder 24 when the hydraulic rod 23 is recovered.

[0030] A mounting block 28 is fixedly connected to the cutting tube 21 , and a through hole 29 is formed in the cutting tube 21 .

[0031] A hydraulic pipe 210 is provided in the connecting pipe 22 for connecting to an external hydraulic machine to control the extension and retraction of the hydraulic rod 23 .

[0032] A square groove is provided on the mounting block 28, and the connecting plate 26 is slidably connected to the mounting block 28 through the square groove. The connecting plate 26 can limit the displacement of the knife seat 24 in the mounting block 28, and a collection structure is provided on one side of the cutting tube 21.

[0033] During use, first, the straw is continuously passed through the through hole 29 into the cutting tube 21 through the external equipment. The straw entering the cutting tube 21 will enter the interior of the cutting tube 21 along the through hole 29 until it moves to the appropriate position. Then, the external hydraulic press is immediately started to drive the hydraulic rod 23 through the hydraulic pipe 210, that is, the hydraulic rod 23 is extended, so that the knife holder 24 fixedly connected to the hydraulic rod 23 is displaced along the direction of the hydraulic rod 23. The displacement of the knife holder 24 will drive the cutting knife 25 installed on the knife holder 24 to move, so that the cutting knife 25 passes through the straw in the through hole 29 and cuts the straw. When the cutting is completed, the cutting knife 25 will remain in the passage through the through hole 29, thereby blocking the subsequent straw passing into the cutting tube 21 to ensure that the incision is complete and smooth. Then, the external hydraulic press is continued to be driven to retract the hydraulic rod 23, and the cutting knife 25 is retracted, so that the subsequent straw continues to pass, and the cut straw is pushed out of the cutting tube 21, thereby completing one cutting.

[0034] Example 2

[0035] Reference Figure 1-4 , which is the second embodiment of the present utility model. This embodiment is different from the first embodiment in that: the collecting structure includes a feeding frame 31 arranged on one side of the cutting tube 21. The feeding frame 31 has the same shape as the end of the cutting tube 21, but the two are only in contact and not connected. The thickness of the feeding frame 31 is the same as the length of the cut straws, that is, the thickness of the feeding frame 31 can only accommodate straws in this direction. A second bracket 32 ​​is arranged on the outside of the feeding frame 31. The second bracket 32 ​​consists of two parts, one part is a foot support for fixing to the ground, and the other part is a mounting frame for installing a motor 33. The motor 33 is mounted on the second bracket 32, and a rotating shaft 34 is arranged on the motor 33. The rotating shaft 34 and the cutting tube 21 are rotatably connected and driven by the motor 33. A limiting rod 35 is fixed on the rotating shaft 34, and the end of the limiting rod 35 has a round block. The feeding frame 31 is provided with a round hole at the limiting rod 35 to accommodate the limiting rod 35, that is, the limiting rod 35 is used to drive the feeding frame 31 to rotate with the rotation of the rotating shaft 34.

[0036] A round rod 36 is fixedly connected to the feeding frame 31. The size of the gap between the round rods 36 is the same as that of the straw. The straw is limited so that the straw can enter the lower collecting frame 37 only in the specified direction. The lower side of the feeding frame 31 is fixedly connected to the collecting frame 37. A cover plate 38 is provided on one side of the collecting frame 37. The cover plate 38 and the collecting frame 37 are movably connected. The cover plate 38 can be removed, and the cover plate 38 is made of transparent material, so that the staff can directly observe the collection situation inside the collecting frame 37 through the cover plate 38.

[0037] During use, when the cut straws are pushed out by the subsequent straws passing through the cutting tube 21, they will directly fall into the feeding frame 31. Because the length of the feeding frame 31 is the same as the length of the straws, the straws entering the feeding frame 31 can only fall into the feeding frame 31 in a state perpendicular to the cover plate 38 and parallel to the round rods 36.

[0038] In addition, as soon as the cutting process begins, the motor 33 will start immediately, and the motor 33 will drive the rotating shaft 34 to rotate, and the rotating shaft 34 is bound to the feeding frame 31 through the limiting rod 35, so that when the rotating shaft 34 rotates, the feeding frame 31 rotates along with the rotation of the rotating shaft 34, and the rotation of the motor 33 is set to swing, that is, the movement range is a swing between 45° and 60° in the clockwise and counterclockwise directions. At this time, the straw entering the feeding frame 31 will remain perpendicular to the cover plate 38 and parallel to the round rod 36 and fall into the gap between the round rod 36, and because the gap size of the round rod 36 is large, the straw will not fall into the gap between the round rod 36. The diameter of the collecting frame 37 is the same as that of the straws, so the straws can directly pass through the gap between the round rods 36 and enter the collecting frame 37. Because the collecting frame 37 and the feeding frame 31 are fixedly connected, when the feeding frame 31 swings, the collecting frame 37 also swings at the same time, thereby shaking the straws in the collecting frame 37 evenly and spreading the straws flat in the collecting frame 37. As the collecting frame 37 gradually collects straws, the operator can directly observe the collection situation inside the collecting frame 37 through the transparent cover 38. If the collection is full, the operator can open the cover 38 to take out the neatly stacked straws.

[0039] The remaining structures are the same as those of Example 1.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
