Description

Technical Field

[0001] The utility model relates to the field of cutting devices, in particular to a roll plastic sheet storage and cutting device. Background Art

[0002] Plastic sheeting rolls, a frequently used consumable, need to be frequently removed from the warehouse and cut to the desired length. With a total length of 1.2 meters, the rolls themselves are quite heavy, weighing approximately 50 kg per roll. Each cut requires the coordinated efforts of at least three people: two to remove the roll and hold it in place, while another pulls it to the desired length. With so many people working together to cut to the desired length, the quality and straightness of the cuts cannot be guaranteed. After cutting, the rolls are then rolled up and returned to the warehouse for storage. This operation is time-consuming and labor-intensive.

[0003] For example, the patent document with publication number CN117184969A discloses a roll plastic sheet storage and cutting device. It includes a vertical storage rack, a rotating mechanism, a cutting knife assembly, a scale assembly, a feed clamping device and a base. The rotating mechanism and the scale assembly are installed on the base, the cutting knife assembly and the feed clamping device are installed on the scale assembly, and the vertical storage rack is installed on the rotating mechanism. The beneficial effects of the present invention are: 1. Through this device, 4 rolls of plastic sheet can be stored, and the site utilization rate is high. At least 2 plastic rolls of different specifications and colors can be placed. When the required color is selected, it can be rotated to the cutting station. 2. The cut length is visible, readable and controllable. Precise cutting and neat cutting edges can be achieved. In the above device, a ruler is used to solve the problem of inconvenient measurement when cutting the roll plastic sheeting. However, since the required size of the plastic sheeting is large in some cases, the range of the ruler does not meet the measurement requirements. At this time, workers still need to hold a tape measure to measure, which increases the labor intensity of the workers and reduces work efficiency. Utility Model Content

The counter 304 is electrically connected to the motor 305. A cutting mechanism is provided in front of the active roller 303. The surfaces of the active roller 303 and the driven roller 307 are wrapped with a rubber layer that increases friction. The staff pulls the plastic sheet through between the driven roller 307 and the active roller 303, and then through between the blade 407 and the cutter bottom plate 401. The cutter upper support plate 403 drives the feeding upper support plate 308 to move downward. At this time, the first spring 306 is compressed, and the feeding upper support plate 308 drives the driven roller 307 to move downward. In this way, the driven roller 307 and the active roller 303 clamp the plastic sheet. The motor 305 drives the active roller 303 to rotate. The number of revolutions of the active roller 303 is recorded by the counter 304 and converted into the length sent and displayed on the counter 304.

The support shaft 105 and the rotating head 104 are fixed by bolts, and then the rotating head 104 is placed in the receiving groove 103. Several horizontally arranged plastic sheeting rolls 106 can be stored vertically on the door-shaped bracket 101. This storage method can make more efficient use of space. The oblique upward opening of the receiving groove 103 can prevent the rotating head 104 from escaping from the receiving groove 103, thereby ensuring the safety of the plastic sheeting roll 106 stored on the door-shaped bracket 101.

[0029] The moving mechanism includes a stud 202 fixedly connected to one side of the door-shaped bracket 101, a guide rod 203 is provided in front of the stud 202, the guide rod 203 is fixedly connected to the door-shaped bracket 101, a moving shell 201 is sleeved on the stud 202, a first bevel gear 204 is rotatably connected in the moving shell 201, the first bevel gear 204 is threadedly connected to the stud 202, a second bevel gear 205 is meshed with one side of the first bevel gear 204, the second bevel gear 205 is rotatably connected to the moving shell 201, and the second bevel gear 205 is rotatably connected to the moving shell 201.

The first bevel gear 204 cooperates with the stud 202 to make the movable shell 201 move axially along the guide rod 203, so that the feeding mechanism reaches near the plastic sheeting reel 106.

[0030] The cutting mechanism includes a cutting base plate 401 fixedly connected to the front side of the base 301, a cutting upper support plate 403 is slidably connected to the cutting base plate 401, a limit knob 404 is rotatably connected to the top of the cutting base plate 401, and the limit knob 404 is used to limit the displacement of the cutting upper support plate 403, a symmetrically arranged second spring 402 is fixedly connected to the cutting base plate 401, the other end of the second spring 402 is fixedly connected to the cutting upper support plate 403, a blade 407 is slidably connected to the bottom of the cutting upper support plate 403, a plurality of third springs 405 are fixedly connected to the top of the blade 407, an electromagnet group 406 is symmetrically installed on the top of the blade 407 and the bottom of the cutting upper support plate 403, and the electromagnet group 406 is electrically connected to the counter 304 The upper support plate 403 of the cutter is fixedly connected to the upper support plate 308 of the feeding material, and the blade 407 is set to an inclined blade. A groove corresponding to the inclined blade is opened on the bottom plate 401 of the cutter. The staff presses the upper support plate 403 of the cutter to move downward. At this time, the second spring 402 is compressed and the limit knob 404 is turned to limit the upper support plate 403 of the cutter. When the number of meters fed reaches the set value, one of the electromagnets in the electromagnet group 406 changes polarity and pushes the blade 407 downward. The blade 407 cuts the plastic sheet downward, and then the polarity of the electromagnet group 406 is restored. The blade 407 is reset under the drive of the third spring 405, thus completing the cutting work of the plastic sheet. The blade of the blade 407 is set to be inclined to cut the plastic sheet more smoothly.

[0031] Working principle: Before cutting, the staff will put the plastic sheeting roll 106 on the support shaft 105, and then install the rotating head 104 at both ends of the support shaft 105. Then, the rotating head 104 will be placed in the receiving groove 103. Several plastic sheeting rolls 106 can be stored vertically on the door-shaped bracket 101. This storage method can make more efficient use of space. When cutting is required, the staff will determine the required type of plastic sheeting and turn the rotating handle 206. The rotating handle 206 drives the second bevel gear 205 to rotate, and the second bevel gear 205 drives the first bevel gear 204 to rotate. The first bevel gear 204 cooperates with the stud 202 to make the movable housing 201 move axially along the guide rod 203, so that the feeding mechanism reaches the vicinity of the plastic sheeting roll 106. The staff pulls the plastic sheeting through between the driven roller 307 and the active roller 303, and then through the blade 407 and the bottom of the cutter. The upper support plate 403 of the cutter is pressed down between the plates 401. At this time, the second spring 402 is compressed and the limit knob 404 is turned to limit the upper support plate 403 of the cutter. The upper support plate 403 of the cutter drives the upper support plate 308 of the feeding material to move downward. At this time, the first spring 306 is compressed and the upper support plate 308 of the feeding material drives the driven roller 307 to move downward. In this way, the driven roller 307 and the active roller 303 clamp the plastic sheet. The motor 305 drives the active roller 303 to rotate. The number of revolutions of the active roller 303 is recorded by the counter 304 and converted into the length sent out and displayed on the counter 304. When the number of meters sent reaches the set value, one of the electromagnets in the electromagnet group 406 changes its polarity and pushes the blade 407 downward. The blade 407 cuts the plastic sheet downward, and then the polarity of the electromagnet group 406 is restored. The blade 407 is reset under the drive of the third spring 405, thus completing the cutting of the plastic sheet.
