Description

Technical Field

[0001] The utility model relates to the technical field of manual guillotine shears, in particular to a small desktop manual guillotine shear. Background Art

[0002] The structure of a small desktop manual guillotine mainly includes components such as a blade, a cutter seat, a cutter rod, a base, a cutter pressure plate, and a cutter fixing screw. Among them, the blade is the key component to achieve the cutting function, the cutter seat is used to fix the blade, the cutter rod is used to control the movement of the blade, the base is used to support the material, the cutter pressure plate is used to fix the material, and the cutter fixing screw is used to adjust the position of the blade. The structural principle is to manually operate the cutter rod to move the blade along the cutter seat to cut the material. The cutter fixing screw can adjust the position of the blade to ensure the accuracy and stability of the cutting;

The improvement is that the edge of the fixed blade is corrugated, and the corrugated edge on the fixed blade can generate movement resistance of the seedling in the edge, and the seedling can be positioned in the initial placement position by squeezing the seedling by the movable blade and the fixed blade during the closing process without applying other external forces. However, in this technical solution, when cutting strip-shaped materials or workpieces with long lengths such as seedlings, it is difficult for the staff to ensure that the length of the material cut each time is roughly the same, and the different operating skills and experience of different staff may lead to differences in cutting length. Secondly, even if the same staff operates at different times, the cutting length will be different due to different operating states, thereby affecting the consistency of the length of the cut material.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 The utility model provides an embodiment: a small desktop manual guillotine, comprising a bottom plate 1 and a support seat 1 2 and a support seat 2 3 fixed on both sides of the top of the bottom plate 1, a screw rod distance adjustment structure 4 is installed between the support seat 1 2 and the support seat 2 3, a rear support plate 5 for supporting one end of a strip workpiece is installed at the movable end of the screw rod distance adjustment structure 4, and a front support plate 6 for supporting the other end of the strip workpiece is fixed on the outer wall of the support seat 1 2 close to the vertical center reference plane of the bottom plate 1, and the distance between the rear support plate 5 and the front support plate 6 is adjusted by the screw rod distance adjustment structure 4 to quickly determine the length of the strip workpiece to be cut and formed;

[0020] The tops of the rear support plate 5 and the front support plate 6 are both provided with a lower notch portion 7 for carrying the strip workpiece, and a swing-down guillotine structure 8 is installed on one side outer wall of the front support plate 6, and the swing-down guillotine structure 8 is used to complete the cutting operation on the strip workpiece material, so that the strip workpiece material is cut and processed;

[0021] The screw rod pitch adjustment structure 4 includes a trapezoidal screw rod 401 rotatably installed between the support seat 1 2 and the support seat 2 3, and a nut sleeve 402 installed at a threaded portion at one end of the surface of the trapezoidal screw rod 401. The nut sleeve 402 is fixed to one side of the inside of the rear support plate 5. One end of the trapezoidal screw rod 401 passes through the outside of the support seat 2 3 and is installed with a turntable. When the staff is adjusting the cutting length of the workpiece, the staff screws the trapezoidal screw rod 401 so that the trapezoidal screw rod 401 drives the nut sleeve 402 and the rear support plate 5 to approach or move away from the front support plate 6.

[0022] A cross bar 403 is fixed on the outer wall of the support seat 2 3 above the trapezoidal screw rod 401, one end of the cross bar 403 penetrates the outside of the rear support plate 5 and is fixedly connected to the outer wall of one side of the front support plate 6. The cross bar 403 supports and guides the horizontal sliding of the rear support plate 5, reducing the processing quality degradation or even unexpected situations caused by shaking or instability of the adjustment workpiece;

[0023] The rear support plate 5 and the front support plate 6 are both made of alloy steel, which has high strength and hardness and can withstand large loads and pressures. Therefore, the rear support plate 5 and the front support plate 6 can maintain a stable structure during operation and are not easily deformed or damaged.

[0024] The swing-down guillotine structure 8 includes a blade body 803 rotatably mounted on the outer wall of one side of the front support plate 6, and a rotating shaft 801 fixed at one end of the blade body 803, a columnar handle is installed at one end of the rotating shaft 801 away from the blade body 803, a guillotine plate 802 for misalignment with the front support plate 6 is fixed at the bottom end of the rotating shaft 801, and an elastic return structure 9 is arranged on the outer wall of the other side of the front support plate 6, and the elastic return structure 9 is used to force the rotating shaft 801 to reset. After the adjustment of the position of the workpiece is completed, the staff holds the end of the rotating shaft 801, and then applies force downward to the rotating shaft 801, so that the rotating shaft 801 and the guillotine plate 802 are turned over with the blade body 803 as the center, so that the workpiece on the top of the front support plate 6 is cut by the guillotine plate 802;

[0025] The elastic return structure 9 includes a swing arm 901 installed on the other end of the blade body 803, and a tension spring 902 hooked on the lower end of the swing arm 901. The other end of the tension spring 902 is hooked with the outer wall of one side of the front support plate 6. When the user no longer applies force to the rotating shaft 801, the tension spring 902 begins to reset from the stretched state, and the tension spring 902 drives the swing arm 901 to reverse and reset through the swing arm 901, that is, the shearing plate 802 and the rotating shaft 801 are automatically lifted, which can ensure that the shearing blade can accurately return to the designed position after cutting is completed, maintain the stability of the shearing blade cutting and the consistency of the initial position, and also facilitate the staff to carry out the next cutting operation.

[0026] When the embodiment of the present application is in use, the staff first adjusts the distance between the rear support plate 5 and the front support plate 6 according to the length of the workpiece to be formed, that is, the staff operates the screw distance adjustment structure 4 so that the screw distance adjustment structure 4 drives the rear support plate 5 to approach or move away from the swing-down guillotine structure 8, thereby adjusting the distance between the rear support plate 5 and the front support plate 6, and the distance is the length of the workpiece to be formed. Then the staff sets the strip workpiece material in the lower notch 7 at the top of the rear support plate 5 and the front support plate 6, and makes the strip workpiece material set up stably, and then completes the cutting operation on the strip workpiece material through the swing-down guillotine structure 8, so that The strip workpiece material is cut and processed, and then the strip workpiece material is pushed and the cutting operation is performed according to the same steps. The guillotine adjusts the distance between the rear support plate 5 and the front support plate 6 through the screw distance adjustment structure 4 to quickly determine the length of the strip workpiece to be cut and formed. It can achieve precise length control to ensure that the length of the strip workpiece cut and formed each time is basically the same, thereby improving the consistency and stability of the workpiece length. Compared with the traditional manual adjustment method, the screw distance adjustment structure 4 can adjust the length through a simple rotation operation, thereby reducing the labor intensity of the operator and improving the convenience and safety of the guillotine operation.
