[0002] Door suction, also commonly known as door touch, is a device that sucks and holds the door in place after it is opened to prevent the door from being closed by wind or touching it. Plastic door touch, as the name suggests, is a door touch device made of plastic material. Compared with other materials such as metal, plastic door touch is lighter, easier to install and use. Plastic door touch has gradually become a popular product on the market because of its beauty, durability, lightness and environmental protection.

[0003] However, the material of plastic door stopper itself has certain weather resistance and wear resistance. However, compared with stronger materials such as metal, plastic door stopper may be more susceptible to damage or deformation during long-term use. In general, door stopper is composed of two components, one large and one small. Generally, plastic door stopper is directly adsorbed together with the help of magnetism and packed in paper box. However, this packaging method has great problems in the logistics and transportation process. Compared with metal door stopper, plastic material is more prone to damage and breakage, especially when encountering bumps that cause the components to separate and move in the packaging box, scratches will appear on the surface of the plastic material, etc. For this reason, we propose a combined packaging equipment for injection molding magnetic door stopper to solve the above problems.

[0030] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 7 The present invention provides a technical solution: a combined packaging device for injection molding magnetic door stopper, comprising an operating table 1, a transmission plate 2 arranged on the top of the operating table 1, a limiting conveying mechanism 3 movably arranged on the top of the transmission plate 2, and a docking winding mechanism 4 located on both sides of the transmission plate 2, the transmission plate 2 is rotatably arranged on the top of the operating table 1, the limiting conveying mechanism 3 is evenly arranged in an array on the top of the transmission plate 2, and the limiting conveying mechanism 3 is used to limit the door magnet body at the bottom of the door stopper, so as to facilitate the subsequent matching packaging with the permanent magnet of the door stopper;

[0032] The docking and winding mechanism 4 is arranged on the top of the operating table 1, and the docking and winding mechanism 4 includes an adjusting frame 41. The adjusting frame 41 is installed on both sides of the transmission disk 2. The height of the adjusting frame 41 can be adjusted according to the height of the assembled door magnet body. When the door stopper needs to be assembled and packaged, it can be clamped on the top of the rotating disk 37 of the limiting conveying mechanism 3, and the plastic film on the rotating roller can be wound on the door magnet body, and the position of the limiting conveying mechanism 3 can be adjusted according to the door stoppers of different sizes, so as to facilitate the subsequent stable docking of the door stopper permanent magnet without deviation. In cooperation with the transmission disk 2 and the docking and winding mechanism 4, the door stopper permanent magnet can be pressed against the top of the door magnet body and wound with the help of the plastic film, so that the door stopper can be assembled and packaged, which can reduce the situation of the door stopper component detaching during the subsequent transportation, and is also convenient for the subsequent unified packaging.

[0033] like Figure 2As shown, during the packaging process, due to the different sizes of door stopper accessories, the positioning center needs to be adjusted during the assembly process to reduce the deviation of the door stopper during the docking and adsorption process, which affects the subsequent guarantee effect. A plurality of transmission chutes 21 are provided on the surface of the transmission disk 2, and the limiting conveying mechanisms 3 are movably provided inside the transmission chutes 21 for adjusting door stopper components of different sizes to prevent deviation during the assembly and adsorption process. The limiting conveying mechanisms 3 can be moved inside the transmission chutes 21 to adjust the position of the docking center.

[0034] like Figure 3 As shown, in order to ensure stability during the process, the limiting conveying mechanism 3 includes a limiting plate 31, a positioning ring 33 and a clamping rod 35. The limiting plate 31 is movably clamped on the top of the transmission plate 2. A telescopic frame 32 is installed on the limiting plate 31. The positioning ring 33 is installed on the top of the telescopic frame 32. The positioning ring 33 is higher than the door magnet body, so that the height of the subsequent door stopper permanent magnet does not exceed the position of the plastic film when it is adsorbed on the door magnet body, and the door stopper can be smoothly docked and packaged. The positioning ring 33 is "C" shaped, and the clamping rod 35 is installed inside the notch at one end of the positioning ring 33. A straight groove is opened on the clamping rod 35, and a movable frame 36 is movably clamped inside the straight groove. A pair of clamping plates 34 are clamped on the positioning ring 33, and a compression shaft 341 is installed at the bottom of the clamping plate 34. The bottom of the compression shaft 341 is clamped on the limiting plate 31.

[0035] The two ends of the movable frame 36 are vertically bent, and the movable frame 36 is movably connected with a rotating roller, and the plastic film is wound on the rotating roller. The position of the rotating roller can move with the movable frame 36 and can be adjusted according to the rubber of the door stopper assembly of different models and sizes, so that the equipment has good applicability.

[0036] like Figure 4 As shown, the plastic film needs to be cut off after completing a single winding and wrapping. Circular holes are provided on the tops of both ends of the clamping rod 35, and a reset shaft 351 is inserted into the circular hole. The reset shaft 351 is elastic. Vertical grooves are provided at both ends of the clamping rod 35, and a connecting tube 352 is rotatably provided inside the vertical groove. The surface of the connecting tube 352 is made of rubber material, and the connecting tube 352 is installed at the bottom of the reset shaft 351. A plurality of cutting blades are provided on the surface of the connecting tube 352. The operator can rotate the reset shaft 351 to make the cutting blades on the surface of the connecting tube 352 cut the plastic film. At the same time, the plastic film can adhere to the rubber layer on the surface of the connecting tube 352 with the help of friction, so that the plastic film can be stretched for wrapping when the next door magnet body is installed, thereby improving the wrapping efficiency.

[0037] like Figure 5As shown, in order to ensure the stability of the plastic film during the packaging and winding process, a rotating disk 37 is rotatably provided on the top of the limiting disk 31, and an annular groove is provided on the side wall of the rotating disk 37, and an air pressure ring is provided inside the annular groove, and a plurality of positioning rods 38 are provided on the outside of the rotating disk 37, and the length of the positioning rods 38 can be adjusted and one end is installed on the outside of the air pressure ring, and a compression ball 371 is installed on the top of the rotating disk 37, and an air supply pipe is provided between the compression ball 371 and the air pressure ring, and the air supply pipe runs through the rotating disk 37, and the compression ball 371 and the air pressure ring are connected by the air supply pipe. As the compression ball 371 is squeezed, the air pressure ring can expand and push the positioning rod 38 to move outward, which can play a supporting role, and the bottom edge of the plastic film is clamped on the outside of the positioning rod 38 to prevent the plastic film from being stuck in the gap between the rotating disk 37 and the limiting disk 31 during the winding process, so as to ensure the stability of the winding.

[0038] A buffer block 382 is installed at one end of the positioning rod 38. The buffer block 382 is used to abut against the bottom of the outer wall of the door magnet body for auxiliary limiting. An arc-shaped pressure plate 381 is provided on the outer wall of the buffer block 382. A plurality of arc-shaped barbs are provided on the arc-shaped pressure plate 381. After the packaging and coating is completed and the door stopper body is removed, the plastic film on the bottom can be pulled under the action of the arc-shaped barbs to cover the bottom edge of the door stopper body, which can ensure the packaging quality of the equipment and cover all the edges of the door stopper to prevent scratches or paint peeling on the edges due to bumps during transportation when it is placed in a paper box.

[0039] like Figure 6 As shown, in order to limit the door stopper permanent magnet, a fixed pad 42 is installed on the top of the inner wall of the adjustment frame 41. The cross-section of the fixed pad 42 is "U"-shaped, and a limiting shaft 44 is rotatably provided at the bottom of the fixed pad 42. The limiting shaft 44 is tubular and a piston rod 45 is inserted inside. A magnetic block is provided inside and at the bottom of the piston rod 45, and the magnetic block has magnetism that attracts the door stopper permanent magnet. The inner hollow diameter of the limiting shaft 44 is smaller than the door stopper permanent magnet, which can prevent the door stopper permanent magnet from getting stuck inside the limiting shaft 44, and can increase In order to increase fault tolerance during the operation of the equipment, a pneumatic tube 43 is provided inside the fixed pad 42. The pneumatic tube 43 is connected to the limit shaft 44 and is connected to an external pneumatic device to control the movement of the piston rod 45 inside the limit shaft 44. Before the door catch permanent magnet is docked and installed, a layer of foam paper can be placed at the bottom of the piston rod 45, and the door catch permanent magnet can be clamped between the positioning pressing pieces 46. The adjustment frame 41 can be used for docking, and the door magnet body and the door catch permanent magnet can be docked, assembled and packaged.

[0040] like Figure 7As shown, in order to ensure the stable clamping of the door stopper permanent magnet, a plurality of arc grooves are opened on the side wall of the limiting shaft 44, and a positioning pressure piece 46 is movably provided inside the arc groove. The cross section of the positioning pressure piece 46 is "U"-shaped. The positioning pressure piece 46 is used to limit the door stopper permanent magnet. The positioning pressure piece 46 can be pressed against the outside of the door stopper permanent magnet under the interaction force to assist in positioning and clamping.

[0041] In order to facilitate the smooth separation of the limiting shaft 44 from the door catch after the subsequent coating is completed, an expansion tube 47 is provided inside the positioning pressing plate 46. The top of the expansion tube 47 is arc-shaped and inserted inside the limiting shaft 44. The expansion tube 47 can deform with the change of the internal air pressure of the limiting shaft 44, thereby changing the gap of the positioning pressing plate 46. After the packaging is completed, the internal pressure of the limiting shaft 44 can be reduced under the action of external air pressure equipment, the piston rod 45 can be retracted, the magnetic block can be separated from the permanent magnet of the door catch, and the expansion tube 47 can be deformed under negative pressure to reduce the gap of the positioning pressing plate 46, so that the limiting shaft 44 and the coated door catch can be separated, thereby avoiding damage to the coated plastic film.

[0042] Working principle: first, when the door catch needs to be assembled and packaged, it can be clamped on the top of the rotating disk 37 of the limiting conveying mechanism 3, and the plastic film on the rotating roller can be wound on the door magnet body, and the position of the limiting conveying mechanism 3 can be adjusted according to the door catches of different sizes, so that the subsequent door catch permanent magnet can be docked stably without deviation, and with the action of the transmission disk 2 and the docking winding mechanism 4, the door catch permanent magnet can be pressed against the top of the door magnet body, and it can be wound with the help of the plastic film, so that the door catch can be assembled and packaged, which can reduce the subsequent In the event that the door stopper assembly is detached during transportation, it is also convenient for subsequent unified boxing. When the bottom of the door magnet body is clamped on the top of the rotating disk 37, the position of the positioning rod 38 can be adjusted, and the bottom side wall of the door magnet body can be clamped between the buffer pads 382. At the same time, the operator can wind the plastic film on the door magnet body, which is convenient for subsequent winding and coating. At the same time, the position of the clamping plate 34 can be adjusted to press the compression shaft 341 at its bottom against the outer wall of the door magnet body, so that the plastic film can be attached to its surface during the winding process, thereby ensuring the packaging quality of the equipment.

[0043] Then, during the winding process, the arc-shaped pressing plate 381 can support the plastic film at the bottom, thereby preventing the plastic film from being stuck in the gap between the rotating disk 37 and the limiting disk 31 during the winding process, thereby ensuring the stability of the equipment operation packaging. After the coating is completed and the door stopper is removed, the arc-shaped barbs on the surface of the arc-shaped pressing plate 381 can stretch the plastic film inward to fit it to the bottom of the door stopper, thereby coating the bottom edge of the door stopper. Before the door stopper permanent magnet is docked and installed, a layer of foam paper can be placed at the bottom of the piston rod 45, and the door stopper permanent magnet can be clamped between the positioning pressing plates 46, and can be docked with the help of the adjustment frame 41, so that the door magnet body and the door stopper permanent magnet can be docked, assembled and packaged.

[0044] Finally, during the wrapping process, the limit shaft 44 rotates, which can drive the door magnet body and the rotating disk 37 at the bottom to rotate, and the plastic film is evenly wound on its surface. At the same time, the foam paper is wrapped inside the plastic film, and the door stopper can be combined and packaged. After the packaging is completed, the internal pressure of the limit shaft 44 can be reduced under the action of the external air pressure equipment, and the piston rod 45 can be retracted. The magnetic block can be separated from the permanent magnet of the door stopper, and the expansion tube 47 can be deformed by negative pressure to reduce the gap of the positioning pressure plate 46, which can facilitate the separation of the limit shaft 44 and the wrapped door stopper. When the operator removes the door stopper, he directly rotates the reset shaft 351, which can make the blade on the surface of the connecting tube 352 cut the plastic film. At the same time, the plastic film can adhere to the rubber layer on the surface of the connecting tube 352 to prevent the plastic film from returning to the rotating roller and requiring the operator to manually stretch it, thereby improving the wrapping efficiency of the equipment.
