Description

Technical Field

[0001] This utility model belongs to the field of plastic particle processing technology, specifically relating to a pelletizer for plastic particle production and processing. Background Technology

[0002] With the development of modern machining industry, the requirements for cutting quality and precision are constantly increasing, as are the demands for improved production efficiency, reduced production costs, and highly intelligent automatic cutting functions. The development of CNC cutting machines must adapt to the requirements of modern machining industry. Cutting machines are categorized into flame cutting machines, plasma cutting machines, laser cutting machines, water jet cutting machines, etc. Currently, in the production of plastic particles, it is necessary to cut the extruded plastic particles into strips to the required particle length.

[0003] Existing pelletizing machines used in plastic pellet production and processing sometimes suffer damage to varying degrees during pelletizing due to various reasons, making repair or replacement inconvenient.

[0004] To address the aforementioned issues, a search revealed a patent application with application number CN202220491309.5 that discloses a user-friendly pelletizer for plastic particle production and processing. The pelletizer includes: an auxiliary pelletizing assembly comprising a base plate; and a worktable, the bottom of which is fixed to the top of the base plate. The worktable has a rotating groove inside, and a motor is fixedly connected to one side of the inner wall of the rotating groove. The output end of the motor is fixedly connected to a lead screw via a coupling. One end of the lead screw is rotatably connected to the other side of the inner wall of the rotating groove via a bearing, and a threaded block is threaded onto the outer surface of the lead screw.

[0005] In the aforementioned prior art, although the pelletizing component and clamping component in the auxiliary pelletizing assembly can pelletize plastic and process it into plastic granules, the cutting machine used for pelletizing requires manual pulling of the limiting rod during installation, followed by inserting the insert block on top of the cutting machine to install and fix it. Furthermore, when removing the cutting machine, the limiting rod still needs to be manually moved out of the insert block. This method of manually pulling the limiting rod every time the cutting machine is installed and disassembled is quite cumbersome. Utility Model Content

[0046] like Figures 1-6 As shown, a pelletizer for producing and processing plastic particles includes a base plate 1, a conveying mechanism 2, a clamping mechanism 3, and a cutting mechanism 4.

[0047] The conveying mechanism 2, clamping mechanism 3 and cutting mechanism 4 are all mounted on the base plate 1;

[0048] The conveying mechanism 2 is horizontally arranged on the base plate 1 along the length direction of the base plate 1. The driving end of the conveying mechanism 2 is connected to the clamping mechanism 3. The clamping end of the clamping mechanism 3 is used to clamp the plastic strip.

[0049] The cutting mechanism 4 includes a mounting frame 41, a vertical drive component 42, a transmission plate 43, a telescopic support assembly 5, a disassembly and assembly assembly 6, and a cutting machine 44;

[0050] The mounting bracket 41 is set on the base plate 1, the vertical drive component 42 is installed on the top of the mounting bracket 41, the drive end of the vertical drive component 42 passes through the top of the mounting bracket 41 and is connected to the transmission plate 43, and the telescopic support assembly 5 is installed on the transmission plate 43.

[0051] The bottom of the disassembly and assembly component 6 is connected to the top of the cutting machine 44, and the disassembly and assembly component 6 is detachably connected to the telescopic support component 5.

[0052] In this embodiment, the vertical drive component 42 is a second hydraulic cylinder, which is fixedly installed on the top of the mounting frame 41. The drive end of the second hydraulic cylinder passes downward through the top of the mounting frame 41 and is fixedly connected to the top of the transmission plate 43. Specifically, a column 47 is vertically fixedly connected to the mounting frame 41, and the right side of the transmission plate 43 is vertically slidably sleeved on the column 47. The cutting machine 44 is detachably connected to the telescopic support component 5 through the disassembly and assembly component 6, which facilitates the disassembly and replacement of the cutting machine 44.

[0053] As a preferred embodiment, the disassembly and assembly component 6 includes a frustum block 61, a connecting rod 62, and a positioning block 63;

[0054] The frustum block 61, the connecting rod 62, and the cutting machine 44 are fixedly connected from top to bottom;

[0055] The upper radius of the frustum block 61 is smaller than the lower radius;

[0056] The positioning block 63 is horizontally fixed to the front side wall of the connecting rod 62, and the length direction of the positioning block 63 is the same as the cutting direction of the cutting machine 44.

[0057] In this embodiment, the cutting disc of the cutting machine 44 is a disc. When the cutting machine 44 is in the installation state, the length direction of the positioning block 63 is the same as the diameter direction of the cutting disc of the cutting machine 44.

[0058] As a preferred embodiment, the telescopic support assembly 5 includes a limiting frame 51, a positioning plate 52, and a telescopic assembly;

[0059] The limiting frame 51 is fixedly installed on the upper surface of the transmission plate 43. The transmission plate 43 and the limiting frame 51 respectively have a lower opening 45 and an upper opening 57 on the corresponding frustum blocks 61. The frustum blocks 61 can pass through the lower opening 45 and the upper opening 57 in sequence.

[0060] Two spaced limiting grooves 46 are provided on the inner side wall of the lower opening 45 corresponding to the positioning block 63, so that the positioning block 63 can pass through vertically.

[0061] The limiting frame 51 is provided with two sets of telescopic components, which are symmetrically distributed on the left and right sides of the lower opening 45.

[0062] The telescopic assembly includes a wedge block 53, a telescopic spring 54, a support rod 55, and a stop block 56;

[0063] The support rod 55 is slidably sleeved on the limiting frame 51 in the left and right direction. The inner and outer ends of the support rod 55 are fixedly connected to the wedge block 53 and the abutment block 56, respectively. The telescopic spring 54 is sleeved on the support rod 55. The inner and outer ends of the telescopic spring 54 are fixedly connected to the outer side wall of the wedge block 53 and the inner side wall of the limiting frame 51, respectively. The inner end face of the wedge block 53 is a downwardly inclined wedge-shaped surface; the wedge-shaped surface faces downward.

[0064] Two clearance grooves 64 are provided on the outer peripheral wall of the frustum corresponding to the two wedge blocks 53, so that the two wedge blocks 53 can pass through vertically. The clearance groove 64 on the front side is located directly above the positioning block 63.

[0065] The positioning plate 52 is fixedly installed on the top of the limiting frame 51. The positioning plate 52 has an inverted "L" shape structure, and the top of the frustum block 61 can abut against the inner top wall of the positioning plate 52.

[0066] In this embodiment, the two limiting grooves 46 on the lower opening 45 are located at the front end and right end of the inner wall of the lower opening 45, respectively. When the cutting machine 44 is in the installation state, the cutting disc of the cutting machine 44 is distributed along the conveying direction perpendicular to the conveying mechanism 2. At this time, the positioning block 63 is located at the front end of the connecting rod 62, and the length direction of the positioning block 63 is the same as the diameter direction of the cutting disc of the cutting machine 44. The two clearance grooves 64 on the frustum block 61 are distributed along the front-back direction. At this time, the cutting machine 44 is moved vertically upward, so that the frustum block 61 passes through the lower opening 45 and the upper opening 57 in sequence. At the same time, the positioning block 63 passes through the limiting groove 46 at the front end. The cutting machine 44 is positioned by the positioning block 63 and the limiting groove 46, so that the cutting disc of the cutting machine 44 can be distributed along the conveying direction perpendicular to the conveying mechanism 2 during the installation process. During the upward movement of the frustum block 61... In the process, the wedge-shaped surfaces of the wedge-shaped blocks 53 on both sides of the frustum block 61 abut against the outer wall of the frustum block 61. As the frustum block 61 moves upward, it abuts against the wedge-shaped blocks 53 outward, thereby driving the wedge-shaped blocks 53 and the support rod 55 to move outward, while compressing the telescopic spring 54, until the wedge-shaped surfaces of the wedge-shaped blocks 53 no longer contact the outer wall of the frustum block 61. At this time, the frustum block 61 moves to the top of the wedge-shaped blocks 53, and the wedge-shaped blocks 53 are not subject to external force. The telescopic spring 54 is also not subject to external force and returns to its extended state, driving the wedge-shaped blocks 53 and the support rod 55 to move inward, so that the top of the wedge-shaped blocks 53 abuts against the bottom of the frustum block 61, thereby supporting the frustum block 61. At this time, the top of the frustum block 61 abuts against the inner top wall of the positioning plate 52, completing the installation of the cutting machine 44. At this time, the positioning block 63 is located above the transmission plate 43 and below the wedge-shaped blocks 53, making the installation process convenient.

[0067] When it is necessary to remove the cutting machine 44 from the transmission plate 43, rotate the cutting machine 44 counterclockwise, causing the positioning block 63 to rotate to the right end of the limiting groove 46. At the same time, the two clearance grooves 64 on the frustum block 61 are located directly above the two wedge blocks 53. Then move the cutting machine 44 downward, so that the positioning block 63 passes through the right end of the limiting groove 46 and the clearance groove 64 passes through the wedge block 53. Continue to move downward until the upper end of the frustum block 61 is separated from the transmission plate 43, thereby removing the cutting machine 44. The disassembly process is convenient.

[0068] The truncated cone structure of the truncated cone 61, which is smaller at the top and larger at the bottom, compresses the wedge block 53 when moving vertically. The horizontal component force generated by the slope of the wedge surface drives the support rod 55 to move outward. The positioning block 63 cooperates with the limiting groove 46 to achieve angular positioning. The length direction of the positioning block 63 is consistent with the diameter direction of the cutting disc, ensuring that the cutting direction is perpendicular to the conveying direction and avoiding tilting errors. This reduces the number of manual adjustment steps and improves positioning accuracy. The wedge surface of the wedge block 53 slides outward under the compression of the truncated cone 61, and the spring stores energy. When the truncated cone 61 is in place, the spring releases and drives the top of the wedge block 53 to press against the bottom of the truncated cone 61, forming a self-locking mechanism.

[0069] As a preferred embodiment, the conveying mechanism 2 includes a motor 21, a support frame 22, a lead screw 23, a slide bar 24, a lead screw nut 25, and a guide sleeve 26;

[0070] The motor 21 is fixedly connected to the right side wall of the support frame 22. The drive end of the motor 21 extends to the left through the right side wall of the support frame 22 and is connected to the right end of the lead screw 23. The left end of the lead screw 23 is rotatably connected to the left inner side wall of the support frame 22. The slide rod 24 is horizontally fixedly installed inside the support frame 22 and is located behind the lead screw 23. The lead screw nut 25 is threadedly connected to the lead screw 23. The guide sleeve 26 is horizontally slidably sleeved on the slide rod 24. The rear side wall of the lead screw nut 25 is fixedly connected to the front side wall of the guide sleeve 26. The bottom of the clamping mechanism 3 is fixedly connected to the top of the lead screw nut 25 and the guide sleeve 26.

[0071] In this embodiment, the motor 21 drives the lead screw 23 to rotate. Under the action of the slide bar 24 and the guide sleeve 26, the nut of the lead screw 23 and the guide sleeve 26 move synchronously along the lead screw 23 and the slide bar 24, respectively, driving the clamping mechanism 3 to move. The lead screw 23 transmission ensures a constant feed speed, driving the nut of the lead screw 23 to move on the lead screw 23, and at the same time driving the guide sleeve 26 to move on the slide bar 24. The slide bar 24 eliminates lateral sway. Through the coordinated use of the motor 21, support frame 22, lead screw 23, slide bar 24, lead screw nut 25 and guide sleeve 26, the clamping mechanism 3 is driven to move, and the feeding of the plastic strip is precisely controlled.

[0072] As a preferred embodiment, the clamping mechanism 3 includes a clamping plate 31, an upper clamping block 32, a lower clamping block 33, a screw 34, and a support spring 35;

[0073] The bottom of the clamping plate 31 is fixedly connected to the top of the lead screw nut 25 and the guide sleeve 26. The top of the support frame 22 is provided with a clearance opening 27 along the length direction. The upper end of the clamping plate 31 passes through the clearance opening 27 upward and can move along the length direction of the support frame 22 within the clearance opening 27.

[0074] The clamping plate 31 has a placement hole 36. The support spring 35 is vertically fixed to the bottom of the placement hole 36. The bottom of the lower clamping block 33 is fixedly connected to the top of the support spring 35. The screw 34 is threaded onto the top of the clamping plate 31. The lower end of the screw 34 passes through the top of the clamping plate 31 and extends into the placement hole 36. The lower end of the screw 34 is fixedly connected to the top of the upper clamping block 32. A handle is fixedly connected to the upper end of the screw 34.

[0075] In this embodiment, the upper clamping block 32 is adjusted by the screw 34, and the support spring 35 provides elastic pressure on the lower clamping block 33 to adapt to the clamping requirements of plastic strips of different diameters.

[0076] As a preferred embodiment, a collection box 7 is also included, which is placed on the base plate 1 and located to the left of the conveying mechanism 2.

[0077] In this embodiment, a collection box 7 is provided to facilitate the collection of cut plastic particles.

[0078] As a preferred embodiment, it also includes a protective component 8, which includes a first hydraulic cylinder 81 and a protective cover 82;

[0079] Two first hydraulic cylinders 81 are provided and both are vertically fixed on the base plate 1. The two first hydraulic cylinders 81 are located on the left and right sides of the conveying mechanism 2, respectively. The driving end of the first hydraulic cylinder 81 is upward and fixedly connected to the inner top wall of the protective cover 82. The protective cover 82 is placed directly above the base plate 1.

[0080] In this embodiment, the protective cover 82 is driven to rise and fall by the first hydraulic cylinder 81, which closes the working area during cutting and prevents debris from flying. Specifically, the protective cover 82 is made of polycarbonate material, which has the characteristics of transparency, impact resistance and lightweight.

[0081] The working principle of this utility model is as follows:

[0082] In use, the upper clamping block 32 is adjusted by the screw 34, and the support spring 35 provides elastic pressure on the lower clamping block 33 to clamp the plastic strip; then the motor 21 is started to drive the lead screw 23 to rotate. Under the action of the slide rod 24 and the guide sleeve 26, the nut of the lead screw 23 and the guide sleeve 26 move synchronously along the lead screw 23 and the slide rod 24 respectively, driving the clamping mechanism 3 to move, ensuring that the plastic strip enters the cutting area at a uniform speed. The vertical drive component 42 of the cutting mechanism 4 drives the cutting machine 44 to move vertically for cutting. When the cutting machine 44 needs to be installed, the cutting machine 44 cooperates with the telescopic support assembly 5 (wedge block 53, telescopic spring 54) through the disassembly and assembly assembly 6 (frustum block 61, connecting rod 62). The conical outer wall of the frustum block 61 presses against the wedge block 53, causing the support rod 55 to move outward and compress the spring. When the frustum block 61 moves to the opening 57 on the limit frame 51, the positioning block 63 cooperates with the limit groove 46 to achieve precise positioning. The spring resets and drives the wedge block 53 to engage with the bottom of the frustum block 61. Meanwhile, the inner top wall of the positioning plate 52 abuts against the top of the frustum block 61, completing automatic locking; when it is necessary to disassemble the cutting machine 44, rotate the cutting machine 44 counterclockwise so that the positioning block 63 aligns with the right limit groove 46, the clearance groove 64 of the frustum block 61 avoids the wedge block 53, the cutting machine 44 moves down, the wedge block 53 disengages from the frustum block 61, the spring releases and pushes the support rod 55 back to its original position, the cutting machine 44 disengages from the support assembly, thereby disassembling the cutting machine 44, reducing the need for manual intervention and facilitating replacement.
