Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to an automatic cutting device for producing sticky mats. Background Art

[0002] Sticky mats, also known as sticky floor adhesives, are primarily used at the entrances and buffer zones of cleanrooms. They effectively remove dust from shoe soles and wheels, minimizing the impact of dust on cleanroom environments. This provides simplified dust removal, resolving the incomplete dust removal issues of other floor mats. A cutting device is required during the production process of sticky mats.

[0003] For example, an automatic cutting device for sticky mat production, with authorization announcement number CN218138400U, belongs to the field of sticky mat production technology and includes a support plate and two blades disposed above the support plate. The top of the support plate is configured with a slot adapted to the base, a bracket is fixed to the top of the base, and two screw holes adapted to the locking bolts are provided on the base and the support plate. Two hydraulic cylinders are fixed to the top of the bracket, and the piston rods of the two hydraulic cylinders are connected to the connecting plate. The bottom end of the connecting plate is provided with two adjustment members, each comprising a bidirectional screw and a housing with a scale. A knob is fixed to one end of the bidirectional screw, and the other end of the bidirectional screw passes through two sliders disposed in the housing and is rotatably connected to the inner wall of the housing. The bottom ends of the two sliders are configured with slots adapted to the blades, and the side walls of the two sliders are provided with two screw holes adapted to the fastening bolts. This automatic cutting device for sticky mat production is easy to adjust and is conducive to controlling the cutting size.

[0004] In practical applications, the above technical solution can only achieve unidirectional cutting of the sticky mat. However, unidirectional cutting may cause local stress and deformation of the sticky mat during cutting, thereby affecting the cutting accuracy of the sticky mat.

[0005] Therefore, it is necessary to invent an automatic cutting device for producing sticky mats to solve the above problems. Utility Model Content

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

[0021] The utility model provides Figure 1-3 The automatic cutting device for producing sticky mats shown in the figure includes a frame 1. A transmission shaft 2 is provided through bearings at both ends of the frame 1. An eccentric wheel 3 is fixedly provided at both ends of the transmission shaft 2. A movable seat 4 is movably provided on the outer side of the eccentric wheel 3 via bearings. A mounting seat 5 is fixedly provided in the middle of one side of the movable seat 4. A mounting groove 6 is formed at the bottom end of the outer wall of the mounting seat 5. A cutter 7 is fixedly provided inside the mounting groove 6 via bolts. The two cutters 7 cut in opposite directions. The two cutters 7 with opposite cutting directions can cut the sticky mat from two directions to prevent deformation of the sticky mat cut.

[0022] Specifically, a guide seat 8 is fixedly arranged in the middle of the other side of the movable seat 4, and the guide seat 8 is arranged in a "C" - shaped structure. A guide slide bar 9 is arranged through the inside of the guide seat 8. The top end of the guide slide bar 9 is fixedly provided with a vertical slide bar 10. A positioning slide sleeve 11 is sleeved on the top end of the vertical slide bar 10, and the positioning slide sleeve 11 is fixedly arranged inside the frame 1. The movement of the movable seat 4 is restricted by the guide seat 8 and the guide slide bar 9, and the movement of the guide slide bar 9 is restricted by the vertical slide bar 10 and the positioning slide sleeve 11. Therefore, the guide slide bar 9 can only move vertically, and the guide seat 8 can only move horizontally. Thus, the mounting seat 5 and the cutting knife 7 outside the movable seat 4 make a nearly circular motion under the guidance of the transmission shaft 2;

[0023] More specifically, two transmission rollers 12 are arranged in the middle of the inner side of the frame 1. A transmission rod 13 is fixedly arranged in the middle of the transmission roller 12, and the transmission rod 13 is arranged through the inner side wall of the frame 1 through a bearing. One end of the transmission rod 13 is fixedly provided with a transmission gear 14. The two transmission gears 14 are meshed with each other. One end of the transmission shaft 2 is fixedly provided with a connecting gear 15, and the two connecting gears 15 are meshed with each other. A driving gear 16 is arranged between the transmission gear 14 and the connecting gear 15 at the lower part. A driving motor 17 is fixedly arranged outside the driving gear 16, and the driving motor 17 is fixedly arranged outside the frame 1. The driving motor 17 can realize the power input to the device;

[0024] Moreover, a support plate 18 is fixedly arranged in the middle of the inner side of the frame 1, and the position of the support plate 18 corresponds to the transmission roller 12 at the lower part. A blanking guide roller 19 is arranged at one end inside the frame 1, and the height of the blanking guide roller 19 is lower than that of the support plate 18. The blanking guide roller 19 can guide the cut dust - sticking pad to facilitate the blanking process.

[0025] Working principle of the utility model:

[0026] When the device is in use, the dust - sticking pad to be cut can be conveyed above the support plate 18 under the guidance of the two transmission rollers 12, and then pass through between the two groups of cutting knives 7. At this time, the driving motor 17 drives the two transmission shafts 2 to rotate through the driving gear 16 and the connecting gear 15. The transmission shaft 2 drives the eccentric wheel 3 to rotate, and the eccentric wheel 3 drives the movable seat 4 to move, making the movable seat 4 rotate around the transmission shaft 2. In this process, the movement of the movable seat 4 is restricted by the guide seat 8 and the guide slide bar 9, and the movement of the guide slide bar 9 is restricted by the vertical slide bar 10 and the positioning slide sleeve 11. Therefore, the guide slide bar 9 can only move vertically, and the guide seat 8 can only move horizontally. Thus, the mounting seat 5 and the cutting knife 7 outside the movable seat 4 make a nearly circular motion under the guidance of the transmission shaft 2. In this process, the two groups of cutting knives 7 can realize the automatic cutting of the dust - sticking pad, and the cut dust - sticking pad is discharged under the guidance of the subsequent feeding and the blanking guide roller 19.
