Description

Technical Field

[0001] This utility model belongs to the technical field of plastic processing equipment, specifically, it relates to a plastic cutting machine with a feeding mechanism. Background Technology

[0002] In the plastics processing industry, plastic cutting machines are essential equipment for cutting plastic sheets and plates into the required shapes and sizes. After cutting, the finished plastic products need to be removed from the cutting machine for subsequent processing or packaging.

[0003] Chinese patent CN210256424U discloses a plastic cutting machine with a novel feeding mechanism, including a support base and a feeding plate. An integral rod is welded between the support base and the upper end of the support base is provided with a dovetail block. Dovetail grooves are provided on both sides of the feeding plate. The dovetail block is slidably connected to the inner side of the dovetail groove. A bearing mounting seat is provided on the surface of the support base. A drive rod is rotatably mounted on the inner side of the bearing mounting seat. During use, the extension and retraction of the cylinder drives the second rack to drive the small gear disk to rotate. Because the small gear disk is located on the surface of the drive rod, and a large gear disk is also mounted on the surface of the drive rod, and the surface of the large gear disk is meshed with the first rack, which is located on the surface of the feeding plate, the extension and retraction of the cylinder can drive the feeding plate to move along the dovetail block for convenient feeding. However, debris and dust are generated during the plastic cutting process. Exposed gear racks, dovetail grooves and other components are prone to accumulating debris, which not only affects the transmission efficiency but may also accelerate the wear of components. At the same time, a large amount of debris accumulating on the cutting machine's worktable will affect the cutting accuracy and the normal operation of the equipment.

[0004] In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this embodiment provides a plastic cutting machine with a feeding mechanism, including: a base 1, the top of the base 1 is in the shape of a "U", and a conveyor belt 17 is connected to the recess; chip removal grooves 9 are opened on the corresponding surfaces of the front and rear side walls of the top of the base 1, and a fan assembly 10 is connected in the chip removal grooves 9; a column 2 is connected to the side wall of the base 1, and a crossbeam 18 is connected to the column 2 through a drive assembly; a connecting block 6 is connected to the surface of the crossbeam 18, and a fixing assembly and a cutting assembly 11 are connected to the bottom of the connecting block 6.

[0028] The top of the base 1 is designed in a U-shape, with a conveyor belt 17 installed in the recess. This conveyor belt 17 is mainly used to carry the plastic material to be cut and to transport the cut plastic parts after cutting, realizing automated material unloading and reducing manual operation. During the cutting process, the plastic material is transported on the conveyor belt 17 to the area below the cutting component 11. After cutting, the finished product continues to move with the conveyor belt 17 to the unloading position, improving work efficiency. Chip removal grooves 9 are opened on the front and rear side walls of the top of the base 1, and fan components 10 are installed inside. Plastic debris generated during the cutting process will fall onto the surface of the base 1. When the fan component 10 is activated, it generates airflow to blow the debris into the chip removal grooves 9, realizing the function of automatic debris cleaning. To prevent debris from accumulating on the workbench and affecting cutting accuracy and equipment operation, and to maintain a clean working environment, the column 2 is connected to the side wall of the base 1 and is connected to the crossbeam 18 through the drive assembly. The drive assembly can drive the crossbeam 18 to move up and down along the column 2, adjusting the height of the crossbeam 18. According to the different thicknesses of plastic materials, the height of the cutting assembly 11 can be adjusted so that the cutting assembly 11 can accurately cut the plastic material, improving the applicability of the equipment. Before cutting, the fixing assembly can fix the plastic material on the conveyor belt 17 to prevent the material from moving during the cutting process and ensure cutting accuracy. The cutting assembly 11 cuts the fixed plastic material to obtain plastic parts of the required shape and size.

[0029] In this embodiment, the fan assembly 10 includes a blower and a suction fan. Two chip removal grooves 9 are opened at the top of the base 1 and are respectively connected to the blower and the suction fan. A collection chamber 15 is opened inside the base 1, and a door 8 is provided on the side wall of the collection chamber 15. The chip removal grooves 9 are connected to the collection chamber 15 through a discharge channel 16. The connection between the discharge channel 16 and the top of the collection chamber 15 is inclined.

[0030] During the cutting process, the blower blows a strong airflow, quickly blowing the plastic debris on the surface of the base 1 towards the opening of the chip removal groove 9, guiding the debris into the chip removal groove 9. The suction fan generates suction, further drawing the debris in the chip removal groove 9 into the discharge channel 16 and transporting it to the collection chamber 15 inside the base 1. The base 1 has a collection chamber 15 inside, with a door 8 on its side wall, which allows workers to regularly open the door 8 to clean the debris accumulated in the collection chamber 15. The chip removal groove 9 is connected to the collection chamber 15 through the discharge channel 16, and the connection between the discharge channel 16 and the top of the collection chamber 15 is inclined. This inclined design utilizes gravity to allow the debris to slide more smoothly into the collection chamber 15, preventing the debris from accumulating and clogging in the discharge channel 16.

[0031] The drive assembly includes a guide rail 3 extending longitudinally from the column 2, a crossbeam 18 connected to the guide rail 3 via a slider 5, and a lead screw 4 connected to the guide rail 3. The lead screw 4 passes through the slider 5 and is threadedly connected to the slider 5. The bottom end of the lead screw 4 is rotatably connected to the column 2, and the top end passes through the column 2 and is connected to the motor 7.

[0032] The column 2 has a longitudinally extending guide rail 3. The crossbeam 18 is connected to the guide rail 3 via a slider 5, which enables the crossbeam 18 to slide up and down on the column 2. A lead screw 4 is installed at the guide rail 3. The lead screw 4 passes through the slider 5 and is threadedly connected to the slider 5. The bottom end of the lead screw 4 is rotatably connected to the column 2, and the top end passes through the column 2 and is connected to the motor 7. When the motor 7 starts, it drives the lead screw 4 to rotate. Due to the threaded transmission relationship between the lead screw 4 and the slider 5, the slider 5 will move along the axial direction of the lead screw 4, thereby driving the crossbeam 18 to rise and fall smoothly on the column 2, so as to accurately adjust the height position of the cutting component 11.

[0033] The connecting block 6 has an inner cavity 14. The fixing components include a telescopic cylinder 13 and a fixing plate 12. The telescopic cylinder 13 is located in the inner cavity 14, and the output end of the telescopic cylinder 13 passes through the inner cavity 14 and is connected to the fixing plate 12. There are two sets of fixing components, and the cutting component 11 is located between the two sets of fixing components.

[0034] The connecting block 6 has an inner cavity 14. The fixing component includes a telescopic cylinder 13 and a fixing plate 12. The telescopic cylinder 13 is installed in the inner cavity 14, and its output end passes through the inner cavity 14 and is connected to the fixing plate 12. Before cutting the plastic material, the telescopic cylinder 13 is activated, pushing the fixing plate 12 downward to press the plastic material on the conveyor belt 17 tightly onto the conveyor belt 17, thus achieving a stable fixation. There are two sets of fixing components, located on both sides of the cutting component 11. During the cutting process, the two sets of fixing components fix the plastic material from both sides, effectively preventing the material from shifting or deforming during cutting, and providing a stable processing foundation for the cutting component 11. The cutting component 11 is located between the two sets of fixing components, and the cutter inside it performs cutting operations on the fixed plastic material under the action of the drive mechanism.

[0035] Working principle:

[0036] The plastic material to be cut is placed on the base 1 conveyor belt 17, which transports it to the underside of the cutting component 11. Two sets of fixing components drive the fixing plate 12 to press down and fix the material through the telescopic cylinder 13. The motor 7 in the driving component drives the lead screw 4 to rotate, causing the crossbeam 18 to rise and fall along the guide rail 3 of the column 2. After precisely adjusting the height of the cutting component 11, the cutting operation is carried out. During cutting, the blower blows the debris from the base 1 into the chip discharge groove 9, and the suction fan sucks the debris into the collection chamber 15 through the discharge channel 16. The inclined channel design uses gravity to assist the debris to slide down. The cut plastic parts are transported to the unloading position by the conveyor belt 17, completing the automated unloading process.
