Abstract
Description
Technical Field
[0001] This utility model relates to the field of screen printing machine technology, specifically to an automatic loading and unloading screen printing machine. Background Technology
[0002] Existing screen printing machines have formed a diverse and mature system that can meet the printing needs of conventional materials such as plastic, glass, and metal. With the segmentation of industrial production, cylindrical containers have become a common carrier in many fields, such as cream bottles in the cosmetics field, reagent tubes in the pharmaceutical field, thermos cups in the daily necessities field, and roller parts in the industrial field. These products are widely used because their shapes are suitable for holding, storage, or assembly needs.
[0003] In screen printing, the traditional method for printing cylindrical materials involves using a mold with a material slot to place the material and initially limit its position to prevent displacement. However, in continuous production, this requires manual placement of each material into the mold and removal of the finished product. While the operation is already simplified enough, there is still room for improvement in mass production processes. Utility Model Content
[0004] The purpose of this invention is to provide an automatic loading and unloading screen printing machine to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic loading and unloading screen printing machine, comprising a base, wherein the screen printing machine is fixedly installed on one side of the upper end of the base, and a material assembly is provided on the side of the base near the screen printing machine;
[0006] The material assembly includes a feeding bin fixedly installed on one side of the base, a storage trough in the middle of the feeding bin, a discharge trough at the lower end of the feeding bin corresponding to the storage trough, and a base directly below the feeding bin.
[0007] An electric cylinder is fixedly installed on one side of the base corresponding to the base. The output end of the electric cylinder is fixedly connected to the side wall of the base. A material trough is opened at the upper end of the base. A first storage trough is opened on the side of the base near the material trough. A first wedge is slidably connected to the first storage trough. A first return spring is fixedly connected between the first wedge and the first storage trough.
[0008] A protrusion is fixedly installed on the side wall of the feeding hopper. A second storage groove is opened at the lower end of the protrusion. A second wedge is slidably connected to the second storage groove. A second return spring is fixedly connected between the second wedge and the second storage groove.
[0009] Preferably, the material assembly further includes a feeding trough located on one side of the base. The feeding trough is inclined and corresponds to the base. The inclination angle of the feeding trough allows the printed cylindrical material to slide naturally down the inclined surface after leaving the material trough, forming a continuous feeding path.
[0010] Preferably, the material trough and the discharge trough form an annular opening. The material trough has a wall curvature of 120 degrees, and the lower end of the discharge trough has a wall curvature of 240 degrees. The 120-degree material trough and the 240-degree discharge trough can be joined to form a 360-degree annular constraint groove. The 120-degree material trough can support and limit the cylindrical material, preventing it from shifting during printing. The 240-degree discharge trough provides support and limitation from the side and below, preventing the material from falling vertically.
[0011] Preferably, the wall of the discharge trough forms a wrap around the cylindrical material in the diametrical direction, and the inner wall of the discharge trough is in contact with the outer wall of the material.
[0012] Preferably, in the natural state of the first return spring, the length of the front end of the first wedge protruding from the opening of the first receiving groove is one-fifth of the diameter of the cylindrical material, and in the natural state of the second return spring, the length of the front end of the second wedge protruding from the opening of the second receiving groove is one-fifth of the diameter of the cylindrical material. This protrusion length of one-fifth of the diameter allows the front end of the wedge to effectively abut against the side wall of the cylindrical material without causing excessive compression of the material or interference with other structures due to excessive protrusion.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: while retaining the concept of mold limiting, the material is supplied by the storage tank and the discharge tank, and the material is conveyed by the lateral contact of the first wedge. Then, the automatic detachment of the printed material is achieved by the contact of the second wedge, forming a continuous loading and unloading process route. This not only continues the mold's limiting stability for cylindrical materials, but also eliminates the manual intervention link, reducing the time cost of material placement and removal. At the same time, the precise cooperation between the wedge and the material tank improves the consistency of the printing position, significantly improving production efficiency while ensuring processing accuracy, and adapting to the needs of mass production.

[0020] 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 protection scope of the present utility model.
[0021] Please see Figure 1-5 The present invention provides the following technical solution:
[0022] An automatic loading and unloading screen printing machine includes a base 1, a screen printing machine 2 fixedly mounted on one side of the upper end of the base 1, and a material assembly disposed on the side of the base 1 near the screen printing machine 2. The material assembly includes a loading bin 3 fixedly mounted on one side of the base 1, a storage trough 4 formed in the middle of the loading bin 3, and a discharge trough 5 formed at the lower end of the loading bin 3 corresponding to the storage trough 4. A base 6 is disposed directly below the loading bin 3. An electric cylinder 7 is fixedly mounted on the side of the base 1 corresponding to the base 6, and the output end of the electric cylinder 7 is fixedly connected to the side wall of the base 6. The upper end of the base 6 is provided with a material trough 8, and the side of the base 6 near the material trough 8 is provided with a first storage trough 9. The first storage trough 9 is slidably connected to a first wedge 10, and a first return spring 11 is fixedly connected between the first wedge 10 and the first storage trough 9. The side wall of the feeding bin 3 is fixedly installed with a protrusion 12, and the lower end of the protrusion 12 is provided with a second storage trough 13. The second storage trough 13 is slidably connected to a second wedge 14, and a second return spring 15 is fixedly connected between the second wedge 14 and the second storage trough 13.
[0023] The material assembly also includes a feeding trough 16 opened on one side of the base 1. The feeding trough 16 is opened at an angle and corresponds to the base 6. The material trough 8 and the discharge trough 5 form an annular groove. The arc of the groove wall of the material trough 8 is 120 degrees, and the arc of the groove wall at the lower end of the discharge trough 5 is 240 degrees. The groove wall of the discharge trough 5 forms a wrap around the diameter of the cylindrical material, and the inner wall of the discharge trough 5 is in contact with the outer wall of the material. In the natural state of the first return spring 11, the front end of the first wedge 10 protrudes from the opening of the first receiving groove 9 by a length equal to one-fifth of the diameter of the cylindrical material. In the natural state of the second return spring 15, the front end of the second wedge 14 protrudes from the opening of the second receiving groove 13 by a length equal to one-fifth of the diameter of the cylindrical material.
[0024] In use, in the initial state, the electric cylinder 7 is in the retracted state, the base 6 is located directly below the feeding bin 3, the material trough 8 is aligned with the discharge trough 5, and the cylindrical material at the bottom of the storage bin 4 falls into the material trough 8 through the discharge trough 5.
[0025] After the equipment is started, the electric cylinder 7 extends, driving the base 6 to move laterally towards the screen printing machine 2. As the base 6 moves, the first wedge 10 protrudes from the first receiving groove 9 under the elastic force of the first return spring 11. The front end of the first wedge 10 laterally abuts against the side wall of the cylindrical material in the material groove 8, pushing the material to move laterally towards the screen printing machine 2 along with the base 6. During this process, the moving cylindrical material squeezes the inclined surface of the second wedge 14, forcing the second wedge 14 to compress the second return spring 15 and retract into the second receiving groove 13, preventing the second wedge 14 from obstructing the lateral movement of the material and ensuring that the material can be smoothly conveyed to the printing station below the screen printing machine 2. When the base 6 moves the material directly below the screen printing machine 2, the electric cylinder 7 stops extending, and the screen printing machine 2 performs the printing operation. At this time, the first wedge 10 still maintains lateral contact with the material, providing unidirectional limitation to ensure the material's stable position during the printing process.
[0026] After printing, the electric cylinder 7 retracts, causing the base 6 to return to its original position away from the screen printing machine 2. During the movement of the base 6, the cylindrical material moves with it; simultaneously, the second wedge 14, no longer compressed, is ejected from the second receiving slot 13 under the elastic force of the second return spring 15, with its front end laterally contacting the side wall of the printed material. As the base 6 continues to retract and move with the electric cylinder 7, the printed material, under the lateral contact of the second wedge 14, gradually shifts relative to the material trough 8 and falls laterally, finally landing in the inclined discharge trough 16 to complete the unloading process. After the base 6 is fully reset, the material trough 8 aligns with the discharge trough 5 again, repeating the above conveying, printing, and unloading process to achieve continuous operation.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
