Description

Technical Field

[0001] The utility model relates to the technical field of plastic cutting, in particular to a strip cutting mechanism. Background Art

[0002] Plastic is mainly composed of carbon, oxygen, hydrogen, nitrogen and other organic or inorganic elements. The finished product is solid, and it is a molten liquid during the manufacturing process. Therefore, it can be heated to melt, pressurized to make it flow, and cooled to solidify, forming various shapes. During the inspection of the plastic track, it is necessary to cut some samples from the surface of the already laid plastic track for inspection.

[0003] In order to reduce the damage to the plastic track, people often use cutting equipment to cut samples on the surface of the plastic track manually. However, manual cutting requires control of the force and has certain proficiency requirements. Inexperienced users are prone to over-cutting or under-cutting. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 5 As shown, the strip cutting mechanism of this embodiment includes a cutting vehicle 1. A driving mechanism 2 is installed inside the cutting vehicle 1. The driving mechanism 2 is a servo motor commonly seen on the market. A driving structure 3 is installed at the output end of the driving mechanism 2. The driving mechanism 2 can drive the driving structure 3 to operate. The upper end of the driving structure 3 is rotatably connected to a disc 4 through a circular shaft. The driving structure 3 can drive the disc 4 to rotate at high speed. The upper edge position of the disc 4 is rotatably connected to a swing arm 6 through a positioning block. The positioning block is directly in a card-connected connection with the disc 4. The upper end of the positioning block is rotatably connected to the swing arm 6. When the disc 4 rotates, the swing arm 6 is driven to perform a periodic curved motion. A telescopic structure 10 is installed at the lower end of the other side of the swing arm 6 through a slider 9. The telescopic structure 10 is a telescopic rod structure commonly seen on the market. The telescopic structure 10 can be driven by electric drive to move in a circular motion. It can perform extension and contraction movements. It should be noted that a mobile power supply needs to be installed inside the cutting vehicle 1 to provide the operation of the driving mechanism 2 and the telescopic structure 10. A cutter 11 is installed at the lower end of the telescopic structure 10. The vertical height of the cutter 11 can be changed by the telescopic structure 10, so that the cutter 11 can adjust the height as needed. The cutter 11 extends to the bottom of the cutting vehicle 1 through a through groove 12 opened at the bottom end of the cutting vehicle 1. The swing arm 6 drives the cutter 11 to perform periodic curved motion. The through groove 12 limits the movement trajectory of the cutter 11, so that the cutter 11 will perform periodic reciprocating motion inside the through groove 12. Through the periodic movement of the cutter 11, the plastic track below can be cut, and the maximum movement trajectory of the cutter 11 can be manually controlled, so that the user does not need to control the operating force.

[0022] Specifically, a fixed plate 7 is installed inside the cutting vehicle 1 at the right side of the disc 4, and a slide groove 13 is provided inside the fixed plate 7 for matching with the slider 9. The slider 9 is slidably connected to the slide groove 13, so that the slider 9 is confined inside the slide groove 13, and a cutter 11 is installed at the lower end of the slider 9, so that the moving trajectory and range of the cutter 11 are further limited.

[0023] Furthermore, through holes 8 communicating with the slide groove 13 are provided at both upper and lower ends of the fixed plate 7, and the lower through hole 8 is communicated with the through groove 12. The two through holes 8, the slide groove 13 and the through groove 12 are connected to form a larger groove, wherein the moving trajectories of the slider 9 and the cutter 11 are both limited inside the above-mentioned groove.

[0024] Furthermore, the lower end of the driving structure 3 is rotatably connected to a support base 14, and the lower end of the support base 14 is connected to the inner bottom end of the cutting vehicle 1. The support base 14 provides support for the driving structure 3 and the disc 4, wherein the driving structure 3 and the support base 14 are in a detachable rotatable connection relationship, and the user can disassemble and replace the driving structure 3 at any time.

[0025] Furthermore, a plurality of positioning holes 5 located on the same horizontal line are provided on the surface of the disk 4, and the interior of the positioning holes 5 is rotatably connected to the swing arm 6 via a positioning block. By providing a plurality of positioning holes 5 located on the same horizontal line on the surface of the disk 4, each positioning hole 5 has a different distance from the center of the disk 4. By installing the swing arm 6 inside different positioning holes 5, the maximum moving distance of the cutter 11 can be changed, thereby facilitating the user to cut according to usage requirements.

[0026] Furthermore, the driving structure 3 includes a rotating shaft 301, a first bevel gear 302, and a second bevel gear 303. The output end of the driving mechanism 2 is equipped with the rotating shaft 301, and the other end of the rotating shaft 301 is equipped with the first bevel gear 302. The lower end of the first bevel gear 302 is meshedly connected with the second bevel gear 303. The upper end of the second bevel gear 303 is connected to the center position of the lower end of the disk 4 through a circular shaft. The rotating shaft 301 is driven to rotate by the driving mechanism 2, and the rotating shaft 301 drives the first bevel gear 302 to rotate. The first bevel gear 302 drives the second bevel gear 303 to rotate, and the second bevel gear 303 drives the disk 4 to rotate. The connection relationship between the second bevel gear 303 and the first bevel gear 302 is as follows: Figure 5 shown.

[0027] The method of using this embodiment is as follows: move the cutting vehicle 1 to the surface of the plastic track, control the telescopic structure 10 to drive the cutter 11 to descend and fit the plastic track, install the swing arm 6 inside the corresponding positioning hole 5 according to the required cutting size, turn on the driving mechanism 2, drive the driving structure 3 to operate through the driving mechanism 2, drive the disc 4 to rotate, the disc 4 will drive the swing arm 6 to perform periodic curved motion, the swing arm 6 drives the cutter 11 to perform periodic curved motion, so that the cutter 11 performs periodic reciprocating cutting on the surface of the plastic track.
