Description

Technical Field

[0001] The present application relates to a slitting device, and in particular to a material slitting device. Background Art

[0002] BMC (Bulk Molding Compound) is a key thermosetting composite material in the compression molding process. It is carefully proportioned and pre-mixed with multiple components such as resin, glass fiber, mineral filler, etc. The finished BMC bulk material is viscous and mixed together and wrapped with a transparent plastic film. When converting the BMC bulk material into small pieces or granules suitable for compression molding or injection molding, cutting equipment is required to cut the wrapped BMC bulk material.

[0003] At present, a common cutting machine design includes a stable base, on which a cutting knife and a hydraulic cylinder that drives it up and down are installed. During operation, workers need to manually lay the BMC mass wrapped with plastic film flat on the base, and then start the hydraulic cylinder to press the cutting knife down to complete the cutting, and then remove the plastic film after cutting.

[0004] Although this method can achieve basic cutting functions, workers need to manually adjust the position of the BMC mass after each cut to ensure uniformity of subsequent cuts. This process is not only cumbersome and time-consuming, but also increases the complexity and error rate of manual operations, and there is obviously room for optimization. Summary of the invention

[0005] The purpose of the present application is to provide a material cutting device to solve the problems of low efficiency and long time consumption in the BMC mass material cutting process in the above-mentioned related technologies.

[0006] The material cutting equipment provided in this application adopts the following technical solution: A material cutting device comprises a base and a cross beam fixed on the base, a cutting knife located below the cross beam and a driving cylinder fixed on the cross beam are arranged on the base, and the end of the telescopic rod of the driving cylinder is fixedly connected to the upper side of the cutting knife; a movable plate is slidably arranged on the base, a driving member is fixedly arranged to drive the movable plate to reciprocate in a direction close to the bottom of the cross beam, a support shaft is rotatably arranged on the movable plate in a vertical direction, a power member is fixedly arranged to drive the support shaft to rotate, and a support platform for placing materials is fixedly arranged at the upper end of the support shaft.

[0007] By adopting the above technical scheme, during the material cutting process, the staff will place the material on the support table in advance, and then use the driving member to drive the movable plate and the support table to slide as a whole in the direction close to the cross beam. In this process, the sheet material on the receiving plate is horizontally cut into strips by the cutting knife; after the cutting in this direction is completed, the movable plate and the support table are reset as a whole, and then the support table is driven to rotate by the power member, and then the movable plate and the support table are driven by the driving member to slide as a whole in the direction close to the cross beam, and the strip material on the receiving plate is cut into small pieces again by the cutting knife; with this arrangement, the corresponding material cutting time is reduced and the material cutting efficiency is improved.

[0009] By adopting the above technical solution, when the material placed on the receiving plate is cut and processed, the driving roller is driven by the driving source to operate, and then the receiving plate and the material on the receiving plate are automatically unloaded together.

When the material is cut, the bottom side of the limit plate can be pressed against the upper side of the material, reducing the possibility of the slitting being skewed due to the looseness of the material when the slitting knife cuts the material.

[0017] By adopting the above technical solution, due to the setting of the abutment rod and the elastic sleeve, when the slitting knife slides up and down, the outer peripheral surface of the elastic sleeve abuts against one side of the slitting knife, so that the residual material adhering to the surface of the slitting knife can be better cleaned by the elastic sleeve, thereby maintaining the slitting effect of the subsequent slitting knife.

[0018] Optionally, connecting rods bent in the same direction are fixedly provided at both ends of the abutment rod, the connecting rods are rotatably connected to the support seat, and the limiting plate is provided with an adjusting member for driving the connecting rod to rotate.

[0022] Optionally, the two abutment rods can rotate along with the connecting rod to a state where they are in tight contact with the material on the support platform.

[0023] By adopting the above technical solution, when the two connecting rods rotate away from each other, the limit plate is adjusted to a state of abutting against the material on the receiving plate. At this time, the abutment rod can rotate along with the connecting rod to a state of abutting against the material on the support platform, so as to better limit the abutment against the material on the receiving plate.

[0024] Optionally, a cavity is provided inside the abutment rod, a connecting pipe connected to an external air pump is fixedly provided at the end of the abutment rod, a plurality of first jet ports are opened on the outer circumference of the abutment rod, and a second jet port overlapping with the first jet port is opened on the elastic sleeve.
