Description

Technical Field

[0001] The invention relates to a floating medicine cutting device, belonging to the technical field of spiral pressing and stretching forming process. Background Art

[0002] At present, a certain type of small-scale continuous spiral extrusion process uses a spiral extrusion die to produce medicine, and then the medicine is sent to the medicine cutting room along the conveyor belt and cut into a specified length by the medicine cutting machine. The existing medicine cutting machine's cutter is driven by a cylinder to complete the cutting along the radial direction of the medicine column. During the cutting process, the medicine column is always in a forward transmission state. The cutting action of the medicine cutting tool will prevent the axial transmission of the medicine column. The axial traction of the medicine column will squeeze the medicine cutting tool, resulting in trapezoidal cross-sections, collapse and other abnormalities on the cut medicine surface. The end face of the medicine column needs to be further machined, which greatly increases the labor cost. Summary of the invention

[0003] The purpose of the present invention is to solve the problem that when the existing medicine cutting device cuts the medicine column in the transmission state, the medicine cutting tool prevents the axial transmission of the medicine column, and the axial traction force of the medicine column will be squeezed by the medicine cutting tool, resulting in trapezoidal section and collapse of the cut medicine surface.

[0004] The objective of the present invention is achieved through the following technical solutions:

[0005] A floating medicine cutting device of the present invention comprises a base, a horizontal slide rail arranged at the upper end of the base, a tool body with a medicine feeding channel horizontally opened in the middle, a medicine column support plate arranged at the lower end of the medicine feeding channel of the tool body, a driving cylinder fixed at the upper end of the tool body, a tool holder connected to the lower end of the telescopic rod of the driving cylinder, a cutting knife fixed at the front side of the lower end of the tool holder, and an elastic pressing mechanism arranged at the rear side of the lower end of the tool holder;

[0006] The elastic clamping mechanism comprises an upper connecting rod fixed to the rear side of the lower end of the knife holder, a pressure block slidably connected to the lower end of the upper connecting rod, and a pressure spring slidably connected between the upper connecting rod and the pressure block; the pressure block extends downward along the upper connecting rod when the pressure spring is free, and the lower surface of the pressure block is lower than the lower cutting surface of the cutter;

[0007] The driving cylinder controls the vertical movement of the knife holder through the telescopic rod. When the telescopic rod of the driving cylinder is in a retracted state, the lower surface of the pressing block is located above the medicine feeding channel. When the telescopic rod of the driving cylinder is in an extended state, the lower cutting surface of the cutter passes over the lower end of the medicine feeding channel.

[0008] The lower end of the tool body is slidably connected to the horizontal slide rail at the upper end of the base, and a return spring is arranged between the front end of the tool body and the base. The return spring pushes the tool body to slide backward along the horizontal slide rail in a free state.

[0009] A medicine column support plate is provided at the lower end of the medicine inlet channel of the tool body to prevent the medicine column from bending downward during the medicine cutting process.

[0010] When cutting medicine, the medicine column to be cut is conveyed forward to the medicine feeding channel of the tool body through the conveyor belt, and the tool holder is controlled to move vertically downward by driving the cylinder. The pressure block in the elastic clamping mechanism first contacts the upper side of the medicine column. As the tool holder continues to move downward, the pressure spring is gradually compressed, increasing the friction between the pressure block and the upper side of the medicine column, so that the tool body and the medicine column move forward horizontally synchronously with the conveyor belt and compress the reset spring; then the tool holder continues to move downward, and the cutter cuts the medicine column downward. After the medicine cutting is completed, the tool holder is controlled to move vertically upward by driving the cylinder, and the cutter and the pressure block are separated from the medicine column in turn. The synchronous movement of the tool body and the medicine column is released, and the tool body is reset backward along the horizontal slide rail under the action of the reset spring. Repeating the above operation can complete the cutting of the next section of the medicine column.

[0011] Beneficial Effects

[0012] The floating medicine cutting device of the present invention realizes continuous medicine cutting of the conveying medicine column. During the medicine cutting process, the entire floating medicine cutting device moves with the medicine column as a whole and completes the cutting. It can eliminate the influence of the forward transmission of the medicine column on the medicine column cutting process, avoid abnormal problems such as trapezoidal sections and collapse during the medicine cutting process, and essentially improve the one-time cutting and forming qualification rate of the medicine column.

[0018] The elastic clamping mechanism 7 includes an upper connecting rod fixed to the rear side of the lower end of the knife holder 6, a pressure block slidably connected to the lower end of the upper connecting rod, and a compression spring slidably connected between the upper connecting rod and the pressure block; the pressure block extends downward along the upper connecting rod when the pressure spring is free, and the lower surface of the pressure block is lower than the lower cutting surface of the cutter 3;

[0019] The driving cylinder 4 controls the vertical movement of the knife holder 6 through the telescopic rod. When the telescopic rod of the driving cylinder 4 is in a retracted state, the lower surface of the pressing block is located above the medicine feeding channel. When the telescopic rod of the driving cylinder 4 is in an extended state, the lower cutting surface of the cutter 3 passes over the lower end of the medicine feeding channel.

[0020] The lower end of the tool body 5 is slidably connected to the horizontal slide rail 9 at the upper end of the base 10, and a return spring 1 is arranged between the front end of the tool body 5 and the base 10. The return spring 1 pushes the tool body 5 to slide backward along the horizontal slide rail 9 in a free state.

[0021] A medicine column support plate is provided at the lower end of the medicine inlet channel of the tool body 5 to prevent the medicine column from bending downward during the medicine cutting process.

[0022] When cutting medicine, the medicine column 8 to be cut is conveyed forward to the medicine feeding channel of the tool body 5 by the conveyor belt, and the tool holder 6 is controlled to move vertically downward by driving the cylinder 4. The pressure block in the elastic clamping mechanism 7 first contacts the upper side of the medicine column 8. As the tool holder 6 continues to move downward, the pressure spring is gradually compressed, increasing the friction between the pressure block and the upper side of the medicine column 8, so that the tool body 5 and the medicine column 8 move forward horizontally synchronously with the conveyor belt and compress the reset spring 1; then the tool holder 6 continues to move downward, and the cutter 3 cuts the medicine column 8 downward. After the medicine cutting is completed, the tool holder 6 is controlled to move vertically upward by driving the cylinder 4, and the cutter 3 and the pressure block are separated from the medicine column 8 in turn, and the synchronous movement of the tool body 5 and the medicine column 8 is released. The tool body 5 is reset backward along the horizontal slide rail 9 under the action of the reset spring 1. Repeating the above operation can complete the cutting of the next section of the medicine column.
