Description

Technical Field

[0001] This utility model relates to the field of plastic PVC sheet processing technology, specifically to a punching device for plastic PVC sheets with waste collection function. Background Technology

[0002] PVC sheets are a common plastic material made of polyvinyl chloride resin. They are characterized by corrosion resistance, strong weather resistance, good processability, and low cost. PVC sheets are widely used in industries such as construction, decoration, advertising, furniture, electrical equipment, and automotive parts.

[0003] When processing PVC sheets, a punching device is required to cut the PVC sheets into the required size and shape. The punching device uses molds and punching pressure to precisely cut, punch, or shape the PVC sheets.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. In the actual operation of some existing ordinary punching devices, after completing the punching process of PVC sheets, operators often need to manually remove and collect the waste material, which is time-consuming and labor-intensive; 2. When performing punching operations on PVC sheets, some existing ordinary punching devices inevitably generate dust, which will be dispersed into the air, not only adversely affecting the surrounding air quality, but also potentially posing a threat to the health of operators. Utility Model Content

[0005] The purpose of this utility model is to provide a die-cutting device for PVC sheets with waste collection function, so as to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a die-cutting device for PVC sheets with waste collection function, including a die-cutting assembly, a dust-collecting assembly installed on the top of the die-cutting assembly, and a lower die and an upper die installed on the inner wall of the die-cutting assembly.

[0006] The punching assembly includes a base plate, a support rod and a mounting frame mounted on the top of the base plate, a collection box slidably mounted on the inner wall of the mounting frame, a mounting plate mounted on the top of the support rod, a guide frame mounted on the bottom of the mounting plate, a U-shaped plate mounted on the top of the mounting plate, a support plate mounted on the front end of the U-shaped plate, a hydraulic push rod penetrating through the top of the U-shaped plate, a fixing plate mounted on the bottom of the hydraulic push rod, a mounting block mounted on the rear end of the mounting plate, a connecting plate mounted on one side of the mounting plate, a connecting rod rotatably mounted through one side of the mounting block, a rotating block and a worm gear mounted on the outer wall of the connecting rod, a fixing frame mounted on the front end of the rotating block, a geared motor mounted on the front end of the connecting plate, and a worm gear mounted on the output end of the geared motor.

[0007] The dust collection assembly includes a dust collection hood and a centrifugal separator. A three-way pipe is installed on one side of the dust collection hood, and a connecting pipe is installed at one end of the three-way pipe. A dust collection bag is installed at the air outlet of the centrifugal separator.

[0008] More preferably, the collection box is provided with slide bars at both the front and rear ends, and the inner wall of the mounting frame is provided with slide grooves at both the front and rear ends, the internal dimensions of which are consistent with the external dimensions of the slide bars, and the slide bars are slidably installed in the slide grooves.

[0009] More preferably, the top of the fixing frame and near the four corners are provided with screw holes, the fixing frame is connected to the lower mold by screws, and the top of the mounting plate is provided with rectangular holes.

[0010] More preferably, the top of the fixing plate and near the four corners are provided with screw holes, and the fixing plate is connected to the upper mold by screws.

[0011] In a further preferred embodiment, the upper mold forms a lifting assembly via a fixed plate and a hydraulic push rod.

[0012] More preferably, the mounting blocks are symmetrically distributed about the vertical center line of the rotating block, and the worm gear and worm are meshed and installed, and the connecting rod forms a rotating mechanism with the reduction motor through the worm gear and worm.

[0013] More preferably, the dust hood is installed on the inner wall of the U-shaped plate, and the centrifugal separator is installed on the top of the support plate, and the connecting pipe is connected to the air inlet of the centrifugal separator. At the same time, the dust hood and the three-way pipe are symmetrically distributed about the vertical center line of the connecting pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, after the PVC sheet is punched using the punching device, the reduction motor is started. The reduction motor drives the worm wheel, connecting rod, rotating block, fixed frame and lower die to rotate through the worm gear. The waste material on the lower die can be automatically poured into the collection box. The collection box recycles the waste material after punching, which can reduce the workload of the workers and improve work efficiency.

[0016] In this invention, when a die-cutting process is used to cut PVC sheets, a centrifugal separator is activated via a dust collection component. The centrifugal separator then uses a three-way pipe, a connecting pipe, and a dust collection hood to extract the dust generated during the cutting process. The dust is then sent into a dust collection bag for collection, preventing the dust generated during the cutting process from drifting into the air and improving the safety of the device during use.
