Technical Field

[0001] The present application relates to the technical field of cutting equipment, and in particular to a cutting pressure plate device. Background Art

[0002] Cutting machines are widely used in industry to cut materials (mainly sheets), such as rubber, plastic, cardboard, fabric, etc.

[0003] A cutting machine generally includes a workbench, a tool holder and a cutting knife. The tool holder slides along the length direction of the unfolded sheet, and the cutter slides on the tool holder in the direction required to be cut. During the cutting operation, the tool holder drives the cutter to the position required to be cut, and the cutter contacts the sheet and cuts the sheet along the sliding direction.

[0004] With regard to the above-mentioned related technologies, some sheets will be deformed immediately after cutting, which will cause the sheets to be cut subsequently to shift or fly away. It is necessary to suspend the cutting work and sort out the sheets, resulting in low cutting efficiency and poor quality of cut products. Summary of the invention

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-2 This application is described in further detail.

[0029] The embodiment of the present application discloses a cutting pressure plate device.

[0030] See also Figure 1-Figure 2 The pressure plate device for cutting includes a fixed frame 1, which is fixed to the tool holder by bolts. A quick release assembly 2 is provided on the fixed frame 1, and a positioning plate 3 is provided on the lower side of the fixed frame 1. The positioning plate 3 is detachably fixed to the fixed frame 1 through the quick release assembly 2. A pressure plate 5 is provided on the lower side of the positioning plate 3, and the pressure plate 5 slides and cooperates with the positioning plate 3 in the vertical direction. A driving assembly 4 is also provided between the positioning plate 3 and the pressure plate 5, and the driving assembly 4 pushes the lower side of the pressure plate 5 to press against the sheet. The pressure plate device for cutting also includes an avoidance hole 6, which runs through the entire device in the vertical direction, and the cutting knife is set in the avoidance hole 6. Before cutting, the staff fixes the fixed frame 1 on the tool holder, and fixes the positioning plate 3 and the pressure plate 5 on the fixed frame 1 through the quick release assembly 2, so that the cutting knife is located in the avoidance hole 6. During the cutting work, the driving assembly 4 drives the lower side of the pressure plate 5 to press against the sheet, which helps to improve the working efficiency and yield rate of the cutting machine.

[0031] The fixing frame 1 is provided with a locking hole 11, which penetrates the fixing frame 1 in the vertical direction. The fixing frame 1 is also provided with a locking groove 12, which penetrates the fixing frame 1 in the vertical direction, and one side of the locking groove 12 in the length direction is open. The quick release assembly 2 includes a locking pin 22, which is vertically arranged and coaxially arranged in the locking hole 11. The locking pin 22 penetrates the positioning plate 3 along its own axial direction. The fixing frame 1 is also provided with a locking bolt 23, which is horizontally arranged, and the axial direction of the locking bolt 23 is parallel to the width direction of the locking groove 12. The locking bolt 23 penetrates the locking groove 12 along its own axial direction and is threadedly connected to the fixing frame 1. The staff inserts the locking pin 22 into the positioning plate 3, inserts the locking pin 22 into the locking hole 11, and tightens the locking bolt 23 so that the outer wall of the locking hole 11 is pressed against the locking pin 22. The quick-release assembly 2 also includes a positioning pin 21, which is vertically arranged and passes through the fixing frame 1 and the positioning plate 3 along its own axis. The positioning frame is relatively fixed to the fixing frame 1 by means of two pins on one side. The positioning plate 3 is disassembled and assembled by rotating the locking bolt 23, which is convenient for the staff to operate and helps to improve work efficiency.

[0032] The pressure plate 5 is provided with a sliding column 7, which is vertically arranged. The sliding column 7 includes a screw rod 71, a column rod 72 is formed on the upper side of the screw rod 71, an abutment block 73 is fixed to the top of the column rod 72, and a rotating rib 74 is formed on the side of the abutment block 73. The pressure plate 5 is provided with a corresponding threaded hole, and the screw rod 71 is threadedly matched with the threaded hole. The staff can rotate the abutment block 73 to screw the screw rod 71 into the pressure plate 5, so that the sliding column 7 and the pressure plate 5 are relatively fixed.

[0033] A sleeve 31 is also fixed on the positioning frame. The sleeve 31 is vertically arranged. The sleeve 31 is coaxially sleeved on the outside of the sliding column 7. The sliding column 7 is slidingly arranged in the sleeve 31. The abutment block 73 is located on the upper side of the sleeve 31. The abutment block 73 can limit the sliding range of the sliding column 7 on the sleeve 31. The staff adjusts the range of the screw rod 71 in the threaded hole and the stroke of the sliding column 7 so that the pressure plate 5 can slide up and down according to the thickness and structure of the sheet to adapt to sheets of different thicknesses. At the same time, the position of the screw rod 71 in the threaded hole needs to ensure that when the cutter is automatically lifted, the pressure plate 5 does not contact the surface of the sheet, thereby reducing the possibility of the pressure plate 5 scratching the sheet during the movement of the knife holder.

[0034] The driving assembly 4 includes a driving spring 41, which is located between the positioning plate 3 and the pressure plate 5, and is sleeved on the sliding column 7. When the pressure plate 5 is in a suspended state, the driving spring 41 is in a relaxed state. When the pressure plate 5 abuts against the upper side of the sheet, the pressure plate and the positioning plate 3 compress the driving spring 41, and the driving spring 41 pushes the lower side of the pressure plate to abut against the upper side of the sheet.

[0035] The sliding column 7 and the sleeve 31 can be arranged in multiple groups on the pressure plate device, and in the embodiment of the present application, they are arranged in four groups. The driving spring 41 can be arranged in multiple groups, and in the embodiment of the present application, they are arranged in two groups.

[0036] The implementation principle of a cutting pressure plate device in an embodiment of the present application is as follows: before cutting begins, the staff fixes the fixed frame 1 to the knife holder by bolts, fixes the positioning plate 3 to the fixed frame 1 by the positioning pin 21 and the locking pin 22, tightens the locking bolt 23, and the outer wall of the locking hole 11 is pressed against the surface of the locking pin 22. The pressure plate 5 is pressed against the surface of the sheet to be cut, and the staff rotates the abutment block 73 to make the positioning plate 3 and the pressure plate 5 in a state of compressing the driving spring 41. Turn on the cutting machine, and the cutting knife and the cutting pressure plate device move in the cutting direction to achieve cutting of the sheet. The cutting pressure plate device set in this way helps to improve the cutting efficiency and yield rate of the cutting machine.
