[0002] PVC sheet, or polyvinyl chloride sheet, is a sheet material made from polyvinyl chloride resin as the main raw material, with the addition of appropriate amounts of plasticizers, stabilizers, lubricants, fillers and other auxiliary materials, through processes such as plasticizing, calendering or extrusion.

[0003] After PVC sheets are produced, they are usually packaged and transported in a unified manner. However, existing PVC sheets are only packaged with plastic film, which can easily lead to problems such as fogging and scratches on the surface of the PVC sheets during transportation. At the same time, the PVC sheets are difficult to handle during the later distribution process because the packaging is too tight. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a paper tube packaging mechanism for PVC sheet products. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A paper tube packaging mechanism for PVC sheet products includes a base 1, characterized in that a packaging mechanism 2 is installed on the top of the base 1;

[0025] The packaging mechanism 2 includes a fixed base 204 and a winding base 206. The bottom of the fixed base 204 is fixedly connected to the top of the base 1, and the bottom of the winding base 206 is rotatably connected to the top of the base 1. The winding base 206 consists of a servo motor and a rotating disk. The servo motor is started by an external power supply, and the servo motor drives the rotating disk to rotate, thereby completing the winding of the packaging film 201 and wrapping the packaging film 201 around the surface of the packaging paper tube 210. A fixed rod 202 is fixedly connected to the top of the fixed base 204, and a film tube 205 is sleeved on the surface of the fixed rod 202. The inner cavity of the film tube 205 is filled with the packaging film 201. A base plate is placed on the top of the winding base 206. 208. A packaging paper tube 210 is installed on the top of the base plate 208. Several packaging paper tubes 210 are arranged in multiple rows and columns. A top plate 207 is installed on the top of each packaging paper tube 210. Both the top plate 207 and the packaging paper tube 210 are covered with a packaging film 201. Kraft paper 212 is placed inside the packaging paper tube 210. Newsprint 211 is attached to the inside of the kraft paper 212. A PVC sheet product body 214 is attached to the inside of the newsprint 211. The kraft paper 212 is placed on the outermost layer. The newsprint 211 and the PVC sheet product body 214 are stacked sequentially. During the packaging process of the PVC sheet product body 214, the kraft paper 212 is first placed on top of the newsprint 211. Paper 212 is laid flat at the bottom, followed by newsprint 211 and PVC sheet product body 214 stacked upwards in sequence, packaged in the order of kraft paper 212 + newsprint 211 + PVC sheet product body 214 + newsprint 211 + PVC sheet product body 214. After packaging, the kraft paper 212, newsprint 211, and PVC sheet product body 214 are manually rolled up and placed inside the packaging paper tube 210 for secondary packaging. The packaging paper tubes 210 are then placed on top of the base plate 208 in sequence. After the packaging paper tubes 210 are arranged, the top plate 207 is installed. The top of the packaging paper tube 210 makes the bottom plate 208, the packaging paper tube 210 and the top plate 207 a whole. Then another set of packaging paper tubes 210 can be stacked on top of the top plate 207. Then one end of the packaging film 201 is fixed to the surface of the packaging paper tube 210. Through the setting of the fixing seat 204, through the servo motor and rotating disk included in the winding seat 206, the servo motor is started by the external power supply. The servo motor drives the rotating disk to rotate, which completes the winding of the packaging film 201 and wraps the packaging film 201 around the surface of the packaging paper tube 210. This prevents the surface of the PVC sheet product body 214 from fogging and scratches during transportation.

[0026] Reference Figure 2 and Figure 3A fixing ring 209 is fixedly connected to the top of the winding base 206. The inner cavity of the fixing ring 209 is engaged with the surface of the base plate 208. The fixing ring 209 positions the base plate 208, allowing it to be stably placed on the top of the winding base 206. This facilitates the winding base 206 to rotate the base plate 208, thereby wrapping the packaging film 201 on the surface of the packaging paper tube 210.

[0027] Reference Figure 2 There are four connecting buckles 213 on both sides of the surface of the bottom plate 208. The inner cavity of the connecting buckle 213 is engaged with the surface of the top plate 207. By setting the connecting buckles 213, the position of multiple packaging paper tubes 210 can be fixed to prevent the multiple packaging paper tubes 210 from shaking during rotation, which would affect the wrapping effect of the packaging film 201.

[0028] Reference Figure 1 A damping ring 203 is fixedly connected to the top of the film tube 205. The inner cavity of the damping ring 203 is rotatably connected to the surface of the fixed rod 202. The damping ring 203 is made of rubber. By setting the damping ring 203, the friction force experienced by the film tube 205 during rotation is increased, thereby reducing the rotation speed of the film tube 205. This keeps the packaging film 201 in a straight state during the winding process and prevents the packaging film 201 from being too loose during the wrapping process, which would affect the wrapping effect on the surface of the packaging paper tube 210.

[0029] Reference Figure 2 , Figure 3 and Figure 5 A positioning mechanism 3 is installed on the top of the winding base 206. The positioning mechanism 3 includes a connecting plate 301 and a positioning groove 303. One side of the connecting plate 301 is in contact with the surface of the fixing ring 209. The positioning grooves 303 are respectively opened on the front and back sides of the base plate 208. A positioning plate 305 is fixedly connected to one side of the connecting plate 301. The surface of the positioning plate 305 is engaged with the inner cavity of the positioning groove 303. The position of the positioning plate 305 is fixed by the setting of the connecting plate 301. The surface of the positioning plate 305 can be inserted into the interior of the base plate 208 by the setting of the positioning groove 303, thereby positioning the base plate 208 and preventing the base plate 208 from detaching from the interior of the fixing ring 209 during rotation, which would affect the normal wrapping of the packaging paper tube 210.

[0030] Reference Figure 2 , Figure 3 and Figure 5Guide rods 304 are slidably connected to both sides of the inner cavity of the connecting plate 301. A fixing plate 302 is fixedly connected to one side of the guide rod 304. The bottom of the fixing plate 302 is fixedly connected to the top of the take-up seat 206. The guide rods 304 guide the movement of the connecting plate 301, improve the stability of the connecting plate 301 during the movement, keep the connecting plate 301 moving horizontally, and prevent the position of the connecting plate 301 from shifting during the movement.

[0031] Reference Figure 5 A spring 306 is fixedly connected to one side of the connecting plate 301. One end of the spring 306 is fixedly connected to the surface of the fixing plate 302. The spring 306 supports the position of the connecting plate 301. When the connecting plate 301 is not under force, the guide rod 304 can restore the deformation and push the connecting plate 301 to move, so that the connecting plate 301 can be quickly reset, making it easy to insert the surface of the positioning plate 305 into the interior of the positioning groove 303.

[0032] Working principle: In the packaging process of the PVC sheet product body 214, kraft paper 212 is first laid flat at the bottom. Then, newsprint 211 and the PVC sheet product body 214 are stacked upwards in sequence, following the order of kraft paper 212 + newsprint 211 + PVC sheet product body 214 + newsprint 211 + PVC sheet product body 214. After packaging, the kraft paper 212, newsprint 211, and PVC sheet product body 214 are manually rolled up and placed inside the packaging paper tube 210 for secondary packaging. Subsequently, the packaging paper tube 210 is placed on top of the base plate 208 and arranged sequentially. Then, the top plate 207 can be installed on top of the packaging paper tube 210, making the bottom plate 208, packaging paper tube 210, and top plate 207 a whole. Next, another set of packaging paper tubes 210 can be stacked on top of the top plate 207, and the surfaces of the connecting buckles 213 can be respectively snapped onto the surfaces of the top plate 207 and the bottom plate 208, thereby fixing the positions of multiple sets of packaging paper tubes 210, allowing them to be wound synchronously and preventing positional shifts during rotation. The surface of the bottom plate 208 is placed inside the fixing ring 209 to fix the position of the bottom plate 208, allowing it to rotate synchronously on top of the fixing seat 204. Finally, one end of the packaging film 201 is fixed... The packaging film 201 is fixed to the surface of the packaging paper tube 210. Through the setting of the fixing seat 204, and the servo motor and rotating disk included in the winding seat 206, the servo motor is started by an external power supply. The servo motor drives the rotating disk to rotate, thus completing the winding of the packaging film 201. The packaging film 201 is wrapped around the surface of the packaging paper tube 210, thereby preventing fogging and scratches on the surface of the PVC sheet product body 214 during transportation. Before the base plate 208 is placed inside the fixing ring 209, the connecting plate 301 is pulled outwards by gripping it. The movement of the connecting plate 301 drives the positioning plate 305 to move, preventing the positioning plate 305 from obstructing the normal movement of the base plate 208. After the base plate 208 is placed, the film is wound up by releasing the fixing ring 209. The connecting plate 301 can be reset when the spring 306 recovers its deformation. The movement of the connecting plate 301 drives the positioning plate 305 to move, so that the surface of the positioning plate 305 can be inserted into the interior of the positioning groove 303. This fixes the position of the base plate 208 and prevents the base plate 208 from shifting during use, which would affect the wrapping effect of the packaging paper tube 210. At the same time, by stacking the newsprint 211 and the PVC sheet product body 214 in sequence, each PVC sheet product body 214 can be extracted during the subsequent distribution process. Each extraction will not affect the packaging effect of the remaining PVC sheet product body 214, thus solving the problem of difficult sheet extraction during distribution.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
