Description

Technical Field

[0001] The utility model belongs to the technical field of canvas sleeve processing, and particularly relates to a cutting device for processing sling canvas sleeves. Background Art

[0002] A sling canvas sleeve is a sleeve-shaped item that combines the design of a sling and the canvas material. It usually has two or more adjustable slings for fixing or hanging items, and the main body is made of wear-resistant and strong canvas material. This design enables the sling canvas sleeve to play its practicality in various occasions, being both convenient to carry and having a certain durability. The cutting device for processing sling canvas sleeves mainly refers to the mechanical equipment used to precisely and efficiently cut the canvas material during the production process of sling canvas sleeves. Such cutting devices usually incorporate modern technologies, such as laser technology, ultrasonic technology, or mechanical cutting technology, etc., to meet different processing requirements.

[0003] The utility model with the publication number "CN221052242U" is a fabric cutting device for processing canvas shoes, which relates to the technical field of fabric cutting. The utility model has a transmission device, and the transmission device includes a conveyor belt and a motor B. Through the cooperation of the force of driving the threaded rod by the motor B and components such as a helical gear, a rack, and a pressing block A, the utility model realizes the rotation of the threaded rod driven by the motor B, then drives the helical gear to transmit through the threaded rod, and then drives the rack to move up and down through the rotation of the helical gear, achieving the effect of driving the pressing block A to move up and down through the up and down movement of the rack, thereby pressing the fabric on the conveyor belt to achieve a positioning effect. Then, through the cooperation of the force of the up and down movement of the rack and components such as a pressing block B, an airbag, and a spring, the utility model realizes the up and down movement of the pressing block B driven by the up and down movement of the rack. When moving downward, it will press the airbag at its bottom, achieving the effect of squeezing the airbag and making the airbag drip liquid into the rack.

[0004] Although the above utility model realizes the up and down movement of the pressing block B driven by the up and down movement of the rack, and when moving downward, it will press the airbag at its bottom, achieving the effect of squeezing the airbag and making the airbag drip liquid into the rack, when cutting the fabric, only driving the blade to descend by the threaded rod on one side to cut the fabric will cause the blade to shake and vibrate during cutting, interfering with the precise movement trajectory of the cutting tool, resulting in non-straight cutting lines, uneven edges, and even possible cutting deviation, seriously affecting the cutting accuracy. Content of the Utility Model

[0005] In view of the problems mentioned in the background art, the purpose of the present utility model is to provide a cutting device for processing sling canvas covers, so as to solve the problem that when the threaded rod drives the blade to descend for cutting the fabric, the blade will shake and vibrate during cutting, interfering with the precise movement trajectory of the cutting tool, resulting in uneven cutting lines, uneven edges, and even possible cutting deviation, seriously affecting the cutting accuracy.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions:

[0007] A cutting device for processing sling canvas covers, including a workbench. An installation groove is opened at the upper end of the workbench, and a conveyor belt is installed inside the installation groove.

The telescopic end of the cylinder penetrates through the installation frame and extends into the installation frame and is fixedly connected to a connecting plate. A lifting plate is installed at the bottom end of the connecting plate. Buffer components are symmetrically installed between the lifting plate and the connection. A cutting tool is movably connected to the bottom end of the lifting plate. Fixing frames are threadedly connected to both ends of the workbench, and clamping components are installed at one end of the fixing frames;

[0008] The buffer component includes a buffer seat, a first limit post, an internal hole, a first buffer spring, and a second limit post. Buffer seats are symmetrically and fixedly connected to the bottom end of the connecting plate and the upper end of the lifting plate.

The upper end inside the internal hole is fixedly connected to a first buffer spring. The other end of the first buffer spring is fixedly connected to a second limit post. The second limit post is slidably connected to the internal hole. The end of the second limit post away from the first buffer spring is fixedly connected to the upper end of the buffer seat at the upper end of the lifting plate. A second buffer spring is sleeved outside the first limit post and the second limit post. The head and tail ends of the second buffer spring are respectively fixedly connected to the opposite ends of the buffer seat, which can effectively absorb the vibration generated during the cutting process, help improve the cutting accuracy, ensure that the edges of the canvas cutting are flat and the dimensions are accurate, and can also reduce the cutting defects generated due to excessive impact force during the cutting process, such as burrs, tears, etc., and improve the overall quality of the canvas cutting.

[0009] As a preferred technical solution, auxiliary guide rods are symmetrically and fixedly connected to both ends of the lifting plate. The end of the auxiliary guide rod away from the lifting plate is fixedly connected to an installation plate. T-shaped grooves are symmetrically opened at both ends inside the installation frame. The end of the installation plate away from the auxiliary guide rod is fixedly connected to a T-shaped block. The T-shaped block is slidably connected to the T-shaped groove, which can ensure that the cutting tool moves along a predetermined trajectory during the cutting process, avoiding deviation and shaking, thereby improving the stability of the cutting.

[0010] As a preferred technical solution, the clamping assembly includes a threaded hole, a threaded rod, a clamping plate and a knob. The upper end of the fixed frame is fixedly connected with a fixed column. A threaded hole is opened at the upper end of the fixed column, and the threaded hole penetrates through the fixed frame. A threaded rod is threadedly connected inside the threaded hole. The upper end of the threaded rod is fixedly connected with a knob, and the bottom end of the threaded rod is rotatably connected with a clamping plate. An anti-slip pad is glued to the bottom end of the clamping plate, and anti-slip bumps are provided on the surface of the anti-slip pad, which can firmly clamp the canvas and prevent the canvas from moving or sliding during the cutting process, resulting in cutting defects such as burrs and tears, thereby ensuring the cutting accuracy, and effectively preventing the canvas from suddenly moving or falling off during the cutting process, avoiding possible accidents.

[0011] As a preferred technical solution, positioning tubes are symmetrically and fixedly connected to the upper end inside the fixed frame. A positioning column is slidably connected inside the positioning tube. One end of the positioning column away from the positioning tube is fixedly connected to the upper end of the clamping plate, which can accurately descend to the specified position and firmly clamp the canvas, and can significantly reduce the cutting error caused by the offset of the canvas position.

[0012] As a preferred technical solution, a first fixing block and a second fixing block are respectively slidably connected to the bottom end of the lifting plate. Connecting columns are symmetrically and fixedly connected to one end of the first fixing block close to the cutting knife. Connecting grooves are symmetrically opened at one end of the second fixing block close to the cutting knife. Through holes are symmetrically opened at one end of the cutting knife. The connecting columns penetrate through the through holes and are inserted into the connecting grooves and fixed by bolts, which allows the operator to quickly complete the replacement of the cutting knife, reduces the downtime, and thus improves the overall cutting efficiency.

[0013] In summary, the utility model mainly has the following beneficial effects:

[0014] First, in the utility model, the air cylinder is started, the control connecting plate drives the lifting plate to descend, and at the same time the lifting drives the auxiliary guide rod to descend, so that the T-shaped block slides inside the T-shaped groove. The lifting plate drives the cutting knife to cut the canvas. At the same time, the second limit post slides inside the built-in hole, the second limit post presses against the first buffer spring, and the first buffer spring is compressed. At the same time, the second buffer springs outside the first limit post and the second limit post are compressed, which can effectively absorb the vibration generated during the cutting process, contribute to improving the cutting accuracy, ensure that the edge of the canvas cutting is smooth and the size is accurate, and can reduce the cutting defects such as burrs and tears caused by excessive impact force during the cutting process, and improve the overall quality of the canvas cutting;

[0015] Second, in the present utility model, the canvas is placed on the conveyor belt, and the conveyor belt is started to control the movement of the canvas. After the canvas moves below the clamping plate, the knob is rotated, causing the knob to drive the threaded rod to rotate. The threaded rod rotates threadedly with the threaded hole, thereby controlling the threaded rod to drive the clamping plate to descend. At the same time, the positioning column slides inside the positioning tube, and the clamping plate drives the anti-slip pad to descend and fit with the surface of the canvas, completing the fixation of the canvas. It can firmly clamp the canvas, prevent the canvas from moving or sliding during the cutting process, and avoid cutting defects such as burrs and tears, thereby ensuring the accuracy of cutting. Moreover, it effectively prevents the canvas from suddenly moving or falling off during the cutting process, avoiding possible accidents. BRIEF DESCRIPTION OF THE DRAWINGS
