Description

Technical Field

[0001] This utility model relates to the field of injection molding particle production technology, and in particular to a cutting device for producing PVC material injection molding particles. Background Technology

[0002] When producing PVC injection molding particles, cutting equipment is usually used to cut the injection molding strip. Traditional PVC injection molding particle production cutting equipment usually requires workers to manually remove the cut PVC injection molding particles when discharging, which is inefficient and inconvenient.

[0003] A search revealed that patent specification CN221985279U discloses a cutting device for producing PVC injection molding particles, including a worktable, a cutting device, and a cutting table. The upper surface of the worktable has a fixed groove, and a protrusion is fixedly connected to the bottom of the cutting table, fitting into the fixed groove. Movable grooves are formed on both sides of the protrusion, and a fixed block is slidably connected inside the movable groove. A spring is fixedly connected to the rear end of the fixed block. The upper surface of the cutting table has a cutting groove, and the two ends of the fixed groove have first inclined surfaces. The bottom of the fixed block has a second inclined surface. By pressing the fixed block into the movable groove and then pulling the protrusion upwards out of the fixed groove, the cutting table can be disassembled, allowing for the removal of the cut PVC injection molding particles from the cutting groove. This facilitates operation and improves overall work efficiency.

[0004] However, the cutting equipment for producing PVC injection molding particles mentioned above still has shortcomings. First, it cannot quickly pre-cool the high-temperature injection molding strip before cutting, which cannot meet the need to quickly cut the injection molding strip into injection molding particles. Second, it still requires manual material handling, and the material handling efficiency is not ideal.

[0005] In view of this, the inventors hope to optimize and improve the existing cutting equipment for the production of PVC material injection molding particles. Summary of the Invention

[0006] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and provide a cutting device for the production of PVC material injection molding particles.

[0007] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: A cutting device for producing PVC material injection molding particles includes a processing box, a cutting tray assembly installed in the middle of the processing box, a rolling cutting assembly installed in the upper part of the processing box, a storage bin at the bottom of the processing box, a discharge pipe installed at the bottom end of the storage bin, and a feeding hole on the side plate of the processing box for easy feeding of injection molding strip into the cutting tray assembly.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5 As shown, this embodiment is a cutting device for producing PVC material injection molding particles, including a processing box 1, a cutting tray assembly 2 installed in the middle of the processing box 1, a rolling cutting assembly 3 installed on the upper part of the processing box 1, a storage bin 4 provided at the bottom of the processing box 1, a discharge pipe 5 installed at the bottom end of the storage bin 4, and a feeding hole 6 provided on the side plate of the processing box 1 to facilitate feeding injection molding strip into the cutting tray assembly 2.

[0025] In this embodiment, the cutting tray assembly 2 includes a stainless steel tray base 201. The tray base 201 has symmetrically formed pressure-bearing grooves 202 on both sides, and the bottom surface of the pressure-bearing grooves 202 has a grid-shaped cutting groove. The tray base 201 has a cooling chamber 203 inside. A first hollow support shaft 205 and a second hollow support shaft 209, communicating with the cooling chamber 203, are symmetrically mounted at both ends of the tray base 201. The outer end of the first hollow support shaft 205 is connected to a cooler 208 via a guide slip ring 206 and an air inlet pipe 207. The second hollow support shaft 209 is connected to the output shaft of a first tilting motor 210 via an anti-slip belt drive component 211. The driven pulley of the anti-slip belt drive component 211 has an exhaust hole communicating with the inner cavity of the second hollow support shaft 209. The cooler 208 and the first tilting motor 210 are mounted on the outside of the processing box 1.

[0026] In this embodiment, the cooling cavity 203 is provided with baffled cold storage plates 204 on its upper and lower surfaces in an alternating manner.

[0027] In this embodiment, the side plate of the processing box 1 is equipped with bearings that provide wear-resistant support for the first hollow support shaft 205 and the second hollow support shaft 209.

[0028] In this embodiment, the roll cutting assembly 3 includes a lifting push rod 301, a first mounting plate 302, a second tilting motor 303, a second mounting plate 304, a linear guide pair 305, a grooved plate 306, a roller 307, and a roll cutter 308. The cylinder of the lifting push rod 301 is fixed to the top plate of the processing box 1. The movable end of the lifting push rod 301 is equipped with the first mounting plate 302. The lower side of the first mounting plate 302 is equipped with the second mounting plate 304 via the second tilting motor 303. The lower side of the second mounting plate 304 is equipped with the grooved plate 306 via the linear guide pair 305. The roller 307, in which the roll cutters 308 are evenly distributed, is movably supported in the grooved plate 306. The spacing between two adjacent roll cutters 308 matches the grid specifications of the roll cutting groove in the pressure groove 202.

[0029] In this embodiment, an annular suspension seat 309 is installed on the lower side of the first mounting plate 302, and an annular suspension member 310, which is slidably restricted in the annular suspension seat 309, is installed on the upper side of the second mounting plate 304.

[0030] In this embodiment, auxiliary suspension plates 311 are symmetrically installed on the outer side of the web portion of the groove plate 306, and roller mounting brackets 312 are symmetrically provided on the lower side of the second mounting plate 304. A row of support rollers 313 that can provide support for the corresponding auxiliary suspension plates 311 are installed on the outer side of the roller mounting brackets 312.

[0031] In this embodiment, an electrically controlled opening valve is installed on the discharge pipe 5 at the bottom of the storage bin 4.

[0032] In this embodiment, a controller is also included, which is connected to the air cooler 208, the first flip motor 210, the lifting push rod 301, the second flip motor 303, the linear guide pair 305, and the electrically controlled opening valve.

[0033] The working principle of this embodiment is as follows: Feeding and Pre-cooling: The operator feeds the injection molding strip into the cutting tray assembly 2 through the feeding hole 6 on the side plate of the processing box 1. At this time, the air cooler 208 works, delivering cold air to the cooling chamber 203 inside the tray seat 201 through the air inlet pipe 207, the air guide slip ring 206, and the first hollow support shaft 205. The cold air flows in the cooling chamber 203 and fully exchanges heat with the injection molding strip through the staggered baffle heat storage plates 204, rapidly pre-cooling the high-temperature injection molding strip.

[0034] Cutting preparation: The controller controls the extension of the lifting push rod 301, pushing the first mounting plate 302 downward, which in turn drives the second mounting plate 304, linear guide pair 305, groove plate 306, roller shaft 307, and roller cutter 308 to move downward, bringing the roller cutter 308 closer to the tray seat 201 of the cutting tray assembly 2. At the same time, the first tilting motor 210 drives the second hollow support shaft to rotate through the anti-slip belt transmission component, which in turn drives the tray seat 201 to tilt, so that the injection molding strip is in a suitable cutting position.

[0035] Roll cutting: The second tilting motor 303 drives the second mounting plate 304 to rotate a certain angle below the first mounting plate 302, adjusting the cutting angle of the roll cutter 308. The linear guide pair 305 drives the grooved plate 306 to move, causing the roller 307 and the roll cutter 308 to roll along a straight line, performing roll cutting on the pre-cooled injection molding strip on the tray seat 201. Because the spacing between two adjacent roll cutters 308 matches the grid specifications of the roll cutting groove in the pressure groove 202, the injection molding strip can be accurately cut into injection molding particles. During the roll cutting process, the annular suspension seat 309 and annular suspension component 310, auxiliary suspension plate 311 and support roller 313, and other structures ensure the stability of the roll cutting.

[0036] Collection and Discharge: The cut injection molding particles fall into the storage bin 4 at the bottom of the processing box 1. When material needs to be retrieved, the controller controls the electrically controlled opening valve on the discharge pipe 5 to open, and the injection molding particles are discharged through the discharge pipe, realizing automatic material retrieval.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to specific implementation methods. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
