Description

Technical Field

[0001] The utility model relates to the technical field of conveying strip-shaped objects, in particular to a negative pressure conveying device for making garbage bags for pet excrement. Background Art

[0002] After pets excrete outside, in order to ensure that the pet excrement does not affect the environment, the pet owner picks up the pet's excrement. At present, in the process of picking up the excrement, plastic belts or paper are often used to pick up the pet's excrement. However, if there is only one plastic bag, the plastic bag is large and it is difficult for the pet owner to grab the pet's excrement. If paper is used, the paper does not block water and the liquid on the excrement can easily adhere to the hand through the paper. For this reason, we propose a bag that glues a plastic bag and paper together to form a garbage bag for picking up pet excrement. When in use, the paper side faces outward, and the hand is put into the plastic bag. The pet's excrement contacts the paper and the hand contacts the plastic bag. This makes it easy to grab the excrement without contaminating the hand.

[0003] In the process of producing pet excrement garbage bags, the plastic belts and cloth belts are cut and then transported to a designated location, and then the cut plastic belts and cloth belts are glued together. Before gluing the plastic belts and cloth belts, the cut plastic belts and cloth belts need to be transported to the designated location. However, the weight of the plastic belts and cloth belts is relatively light, and they need to be transported slowly during the transportation process. If they are transported quickly, the plastic belts and cloth belts will float, and the position between the plastic belts and cloth belts will change, and the plastic belts and cloth belts may even separate. Slow movement will reduce the production speed of pet excrement garbage bags, so a device is needed to ensure the rapid transportation of the plastic belts and cloth belts, and also to ensure that the plastic belts and cloth belts do not move.

[0022] Example 1

[0023] See also Figures 1-4 As shown, this embodiment provides a negative pressure conveying device for making pet excrement garbage bags, including a mounting frame, on which a hanging device 1, a 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, and 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 correcting device 2 respectively, and the 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 adhesion between the cloth belt and the plastic belt. After the 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, and the positioning device 3 fits the plastic belt and the cloth belt to show the plastic belt and the cloth belt after the correction. Whether the position is accurate is determined by separating the plastic belt and the cloth belt through the positioning device 3, wherein the heat sealing device 4 heat-seals the plastic belt to divide the plastic belt into multiple spaces, and the belt flattening mechanism 5 flattens the plastic belt and the cloth belt, and cuts the cloth belt and the plastic belt through the cutting mechanism 6 after the plastic belt and the cloth belt are flattened, 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] In order to enable the adsorption conveying mechanism 7 to transport the cut plastic tape and cloth tape quickly and stably, the structure of the adsorption conveying mechanism 7 is refined. Please refer to Figure 2-Figure 3As shown, the adsorption conveying mechanism 7 includes a side frame 71, a conveyor belt 74 is provided on the side frame 71, a guide is provided inside the conveyor belt 74, a plurality of holes are opened on the conveyor belt 74, a driving member is provided inside the conveyor belt 74, the driving member drives the conveyor belt 74 to rotate, the conveyor belt 74 receives the plastic belt and the cloth belt, and the guide performs negative pressure adsorption on the plastic belt and the cloth belt on the conveyor belt 74 through the holes, so as to position the cloth belt and the plastic belt received on the conveyor belt 74, and by positioning the position of the cloth belt and the plastic belt, the plastic belt and the cloth belt will not move during the transportation process, thereby speeding up the transportation of the plastic belt and the cloth belt, and speeding up the production speed of pet excrement garbage bags.

[0025] Among them, because the plastic belt and the cloth belt are arranged up and down, they are also cut separately when the cutting mechanism 6 cuts. In order to facilitate the reception of the cut plastic belt and cloth belt, one end of the conveyor belt 74 is tilted downward. After the cutting mechanism 6 cuts the cloth belt, the downwardly tilted part of the conveyor belt 74 first receives the cloth belt cut by the cutting mechanism 6. After the conveyor belt 74 receives the cloth belt, the driving member drives the conveyor belt 74 to rotate, so that the cloth belt moves to the position where the cutting mechanism 6 cuts the plastic belt, and then receives the plastic belt cut by the cutting mechanism 6, so that one end of the plastic belt covers the cloth belt, and one end of the plastic bag covers the cloth, so as to facilitate the subsequent operation of the plastic belt and cloth belt by the gluing mechanism and the turning mechanism.

[0026] Among them, the driving part includes several rollers 72 arranged inside the conveyor belt 74, two of which are arranged horizontally to form a horizontal platform on the upper side of the conveyor belt 74. The horizontally arranged platform on the conveyor belt 74 is used for the gluing mechanism and the turning mechanism to process the plastic belt and the cloth belt. At the same time, a driving motor 73 is provided at one end of the roller 72. The driving motor 73 drives the roller 72 to rotate, and several rollers 72 rotate synchronously. The synchronously rotating driving motor 73 drives several rollers 72 to rotate, so that the roller 72 can stably drive the conveyor belt 74 to rotate.

[0027] The guide member 76 is provided with a horizontal box 75, which is arranged horizontally, and receives one end of the horizontal box 75, which is arranged horizontally, and receives the downwardly inclined end of the conveyor belt 74. The upper side walls of the horizontal box 75 and the inclined box 76 are in sliding contact with the side walls of the conveyor belt 74. When the conveyor belt 74 rotates, the inner side wall of the conveyor belt 74 is in sliding contact with the upper side of the horizontal box 75 and the inclined box 76. At the same time, a cavity is formed between the conveyor belt 74, the horizontal box 75 and the inclined box 76. A plurality of suction pumps 77 are provided on the lower side of the horizontal box 75 and the inclined box 76. The suction pumps 77 are fixed to the side frame 71 and are connected to the lower side of the horizontal box 75 and the inclined box 76 through pipes. When the suction pumps 77 are working, they absorb the horizontal box 75, the inclined box 76 and the inclined box 76. The cavity between the conveyor belts 74 reduces the gas in the cavity, and when the gas in the cavity is reduced, it will absorb the conveyor belt 74. At this time, the holes on the conveyor belt 74 will guide the external gas into the cavity. When the cloth belt and plastic belt are on the conveyor belt 74, the cloth belt and plastic belt are fixed on the conveyor belt 74 by the force of the gas moving into the cavity. Because the cavity between the conveyor belt 74 and the horizontal box 75 and the tilting box 76 is large, it is easy for the cavity to have insufficient suction force on the cloth belt and plastic belt. Therefore, several partition plates 78 are fixed inside the horizontal box 75 and the tilting box 76. The partition plates 78 separate the interior of the horizontal box 75 and the tilting box 76 into multiple chambers. The suction pump 77 absorbs the gas in the chamber through the pipe, and the chamber absorbs the external gas through the holes. The plastic belt and cloth belt set on the conveyor belt 74 are fixed on the conveyor belt 74 with the help of the force of the chamber absorbing air, thereby strengthening the stability of the cloth belt and plastic belt on the conveyor belt 74 and ensuring stable transportation of the cloth belt and plastic belt.
