Description

Technical Field

[0001] The utility model relates to the technical field of strip cutting, and specifically, to a cutting device for making pet excrement garbage bags. Background Art

[0002] After a pet excretes outdoors, to ensure that the pet excrement does not affect the environment, the pet owner will pick up the pet excrement. Currently, during the process of picking up excrement, plastic bags or paper are often used for picking up. However, if there is only one plastic bag and the plastic bag is large, it is not easy for the pet owner to grab the pet excrement. And if paper is used, since the paper does not block water, the liquid on the excrement easily adheres to the hand through the paper. For this reason, we propose a bag that combines a plastic bag and paper to form a garbage bag for picking up pet excrement. When in use, the paper side faces outwards, the hand is put into the plastic bag, the pet feces contact the paper, and the hand contacts the plastic bag. In this way, it is convenient to grab the feces and the hand will not be polluted.

[0003] During the production process of pet excrement garbage bags, the plastic strip and the cloth strip will be cut. Currently, when cutting the plastic strip and the cloth strip, a cutting knife is used to move up and down to cut the plastic strip and the cloth strip. However, when using the up-and-down cutting method and cutting when the plastic strip and the cloth strip are tightened, it is easy for the plastic strip and the cloth strip to have elastic retraction, which easily causes the plastic strip and the cloth strip to curl. At the same time, after cutting the plastic strip by using the up-and-down movement method, the subsequent plastic strip and the cloth strip are not easy to move, which easily causes the accumulation of the plastic strip and the cloth strip. At this time, manual adjustment by workers is required, reducing the cutting speed of the plastic strip and the cloth strip. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cutting device for making pet excrement garbage bags to solve the problems raised in the above background art.

[0022] Example 1

[0023] See also Figures 1 - 4 As shown, the present embodiment provides a cutting device for making pet excrement garbage bags, including a mounting frame, on which a hanging device 1, a deviation correcting device 2, a positioning device 3, a heat sealing device 4, a belt flattening mechanism 5, a cutting mechanism 6, an adsorption conveying mechanism 7 and a feeding device 8 are sequentially arranged, the hanging device 1 is provided with a plastic belt roll at the upper side, the cross section of the plastic belt is a ring structure, the hanging device 1 is provided with a cloth belt roll at the lower side, one end of the plastic belt and the cloth belt passes through the deviation correcting device 2 respectively, the deviation correcting device 2 adjusts the position of the plastic belt and the cloth belt to ensure that there is no displacement difference between the plastic bag and the cloth belt, so as to facilitate the mutual fitting of the cloth belt and the plastic belt, after the deviation correcting device 2 adjusts the position of the cloth belt and the plastic belt, the plastic belt and the cloth belt pass through the positioning device 3, the positioning device 3 fits the plastic belt and the cloth belt to show the position of the plastic belt and the cloth belt after the deviation correction. Whether the position is accurate, the plastic belt and the cloth belt are separated by the positioning device 3, wherein the heat sealing device 4 heat-seals the plastic belt to divide the plastic belt into multiple spaces, the belt flattening mechanism 5 flattens the plastic belt and the cloth belt, and after the plastic belt and the cloth belt are flattened, the cloth belt and the plastic belt are cut by the cutting mechanism 6, and the cut cloth belt and plastic belt are taken over by the adsorption conveying mechanism 7. At this time, the plastic belt is on the upper side of the cloth belt, and the cloth belt and the plastic belt are staggered so that one end of the cloth belt extends out of the plastic belt. The adsorption conveying mechanism 7 transports the plastic bag and the cloth belt away, and at the same time, a gluing mechanism and a turning mechanism are installed on the upper side of the adsorption conveying mechanism 7. The gluing mechanism applies glue to the plastic belt, and after the gluing is completed, the turning mechanism flips one end of the cloth belt extending out of the plastic belt onto the plastic belt, so that the cloth belt and the plastic belt are bonded together, and then the feeding device 8 transports the prepared bag away.

[0024] To ensure the stability of the cutting mechanism 6 during cutting and enable the plastic tape and cloth tape to continue moving after the cutting mechanism 6 cuts the plastic tape and cloth tape, the structure of the cutting mechanism 6 is refined. The cutting mechanism 6 includes two cutting members, which respectively cut the plastic tape and cloth tape. The cutting member includes a connecting plate 61 fixed to the mounting frame. On the upper side of the connecting plate 61, there are two cutting members 67 arranged vertically. A plastic tape or cloth tape is arranged between the two cutting members 67. When the two cutting members 67 rotate, the plastic bag or cloth tape is cut off. The cutting member 67 includes a roller shaft 671. On the upper side of the connecting plate 61, two fixing plates 62 are fixed. The plastic tape and cloth tape are arranged between the two fixing plates 62. A roller shaft 671 is rotatably connected between the two fixing plates 62. The position of one roller shaft 671 is fixed. At the same time, on the upper side of the fixing plate 62, there is a sliding plate 64. Another roller shaft 671 is rotatably connected between the two sliding plates 64. On one side of one of the fixing plates 62, there is a driving motor 65. The driving motor 65 drives the two cutting members 67 to rotate in opposite directions through a gearbox, so that the two cutting members 67 can squeeze the plastic tape and cloth tape. At the same time, the two cutting members 67 are symmetrically arranged up and down. The roller shaft 671 on the upper side rotates clockwise, and the roller shaft 671 on the lower side rotates counterclockwise. When the plastic tape and cloth tape are placed between the two roller shafts 671, the two rotating roller shafts 671 drive the plastic bag and cloth to move, ensuring the normal conveyance of the plastic tape and cloth.

[0025] A placement groove 678 is formed on the roller shaft 671. An installation head 673 is arranged in the placement groove 678. The installation head 673 is screw-connected with a cutting blade 674. During the rotation of the two cutting members 67, the ends of the two cutting blades 674 come into contact to cut off the plastic tape or cloth tape, so that the plastic tape and cloth tape are cut into sections. A sliding groove 677 is formed on the placement groove 678. A sliding block 675 is fixed to the lower side of the installation head 673. The sliding block 675 is slidably arranged inside the sliding groove 677. A plurality of screw rods 676 are rotatably connected to the bottom of the sliding block 675. The screw rods 676 are threadedly connected to the roller shaft 671. By rotating the screw rods 676, the screw rods 676 drive the sliding block 675 to move inside the sliding groove 677, causing the cutting blade 674 to move closer to or farther away from the axis of the roller shaft 671, so as to facilitate the height adjustment of the two cutting members 67 according to the thickness of the plastic tape and cloth tape to be cut, ensuring the cutting of plastic tapes and cloth tapes of different thicknesses by the cutting blade 674.

[0026] During the process of the cutting blade 674 cutting the plastic tape and the cloth tape, in order to prevent the plastic tape and the cloth tape from retracting and bending, and to ensure the normal conveyance of the plastic tape and the cloth tape, a clamping block 672 is provided on one side of the mounting head 673. One end of the clamping block 672 close to the mounting head 673 is offset in a direction away from the axis of the roller 671, that is, the side of the clamping block 672 away from the mounting head 673 is an elliptical outer arc surface. At the same time, the clamping block 672 is inserted into the roller 671 and positioned with screws. When the two clamping blocks 672 rotate, they clamp and convey the plastic tape and the cloth tape. When the two rollers 671 rotate, when the two clamping blocks 672 move closer to each other, the arc-shaped sides of the two clamping blocks 672 gradually approach the plastic tape and the cloth tape. When the cutting blade 674 cuts the plastic tape and the cloth tape, the two clamping blocks 672 squeeze the plastic tape and the cloth tape to position the plastic tape and the cloth tape, so that when the cutting blade 674 cuts the plastic tape and the cloth tape, the plastic tape and the cloth tape will not retract. At the same time, the plastic tape and the cloth tape clamped by the two clamping blocks 672 will follow the rotation of the cutting member 67, so that the cut ends of the plastic tape and the cloth tape are conveyed to the other side of the cutting mechanism 6, thereby ensuring the normal conveyance of the plastic tape and the cloth tape.

[0027] On the side of the clamping block 672 close to the mounting head 673 is an inclined surface inclined in the direction of approaching the mounting head 673, and on the side of the mounting head 673 close to the clamping block 672 is provided an inclined surface adapted to the inclined surface on one side of the clamping block 672. When the mounting head 673 moves, the clamping block 672 blocks the mounting head 673, restricting the displacement distance of the cutting blade 674 and preventing the cutting blade 674 from protruding out too much and reducing the stability of the cutting blade 674, thereby enhancing the cutting effect of the two cutting members 67 on the plastic tape and the cloth tape.

[0028] In order to facilitate placing the plastic tape and the cloth tape between the two cutting members 67, a sliding frame 63 is fixed on the upper side of the fixing plate 62. A sliding plate 64 is slidably arranged inside the sliding frame 63, and a threaded rod 66 is threadedly connected to the sliding frame 63. One end of the threaded rod 66 is rotatably connected to the sliding plate 64. When the threaded rod 66 rotates, it drives the sliding plate 64 to move upward, so that the sliding plate 64 drives the upper cutting member 67 to move upward, expanding the distance between the two cutting members 67. After the plastic tape and the cloth tape pass through the two cutting members 67, the threaded rod 66 is rotated in the reverse direction to make the two cutting members 67 approach each other. When the two clamping blocks 672 can clamp the plastic tape and the cloth tape during the process of approaching each other, the rotation of the threaded rod 66 is stopped. By rotating the screw 676, the distance between the two cutting blades 674 is adjusted so that when the two clamping blocks 672 clamp and fix the plastic tape and the cloth tape, the two cutting blades 674 can cut the plastic bag and the cloth tape. After adjusting the position of the cutting member 67, the driving motor 65 drives the two cutting members 67 to rotate, so that the cutting member 67 cuts the plastic tape and the cloth tape.
