DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model, but not to limit the scope of the utility model.

[0026] Embodiment 1:

[0027] Referring to Figure 1 , Figure 2 , Figure 3 , the disposable plastic apron automatic forming machine comprises a frame 1 and further comprises: a conveying mechanism arranged on the frame 1; a mounting bracket 2 fixedly connected to the frame 1; a mounting plate 202 connected to the mounting bracket 2 in a lifting manner; a forming die 203 fixedly installed on the mounting plate 202; a positioning frame 3 connected to the mounting plate 202 in a sliding manner and located below the forming die 203, wherein two ends of the positioning frame 3 are symmetrically fixedly connected with connecting seats 301, the two ends of the mounting plate 202 are symmetrically fixedly connected with guide rods 302, the connecting seats 301 are connected to the guide rods 302 in a sliding manner, and the guide rods 302 are fixedly connected with limiting blocks 303; springs 304 are sleeved on the guide rods 302 and located between the limiting blocks 303 and the mounting plate 202; a connecting block 4 is connected to the inner walls on the two sides of the positioning frame 3 in a sliding manner; a brush 401 is fixedly installed on the connecting block 4, wherein the mounting plate 202 is provided with a driving part for driving the connecting block 4 to move.

[0028] The air cylinder 201 is fixedly installed on the mounting frame 2, and the mounting plate 202 is fixedly connected with the output end of the air cylinder 201.

[0029] The conveying mechanism comprises a driving shaft 101 and a connecting shaft 102, both of which are rotatably connected to the frame 1 and are located at two ends of the frame 1 respectively, and the driving shaft 101 and the connecting shaft 102 are connected through a transmission belt 103.

[0030] The motor 104 is fixedly installed on the frame 1, and the driving shaft 101 is fixedly connected with the output end of the motor 104.

[0031] Firstly, the plastic film is placed on the transmission belt 103 of the conveying mechanism, the motor 104 is started, the motor 104 drives the driving shaft 101 to rotate, so that the transmission belt 103 starts to convey the plastic film to the position of the positioning frame 3 below the forming die 203, then the air cylinder 201 is started, the air cylinder 201 drives the mounting plate 202 to descend, and the forming die 203 and the positioning frame 3 move downward synchronously with the descent of the mounting plate 202, since the position of the positioning frame 3 is lower than that of the forming die 203, the positioning frame 3 first contacts the plastic film, preliminarily positions the film by using the frame thereof, limits the movement of the film in the horizontal direction, and ensures that the plastic film is always in the correct processing position in the pressing and shearing process of the forming die 203, so as to ensure the dimensional accuracy and shape accuracy of the formed product.

[0032] When the positioning frame 3 contacts the plastic film, the mounting plate 202 continues to descend, so that the forming die 203 is in close contact with the plastic film in the positioning frame 3, and the plastic film is pressed and sheared under the action of pressure and the shape of the die, so as to be formed into the shape of a disposable plastic apron.

[0033] At the same time, in the process of continuing to move downward, the mounting plate 202 drives the connecting seat 301 to move upward on the guide rod 302 and compresses the spring 304, and the spring 304 stores elastic potential energy in the process of compression, and this part of energy will play a role when the mounting plate 202 rises subsequently, and the existence of the spring 304 plays a buffering effect, so that it can absorb part of the impact force when the mounting plate 202 descends, avoids that the positioning frame 3 generates sudden and excessive impact force on the film, so as to better protect the film from being damaged, and at the same time, the positioning action of the positioning frame 3 on the film is more stable.

[0034] When the forming operation is completed, the cylinder 201 drives the mounting plate 202 to rise, at this time, the spring 304 starts to release the elastic force in the previously compressed state, pushes the positioning frame 3 to continue to contact the formed film, prevents the film from moving up with the forming die 203 due to the adhesion between them, causing the film to deform or damage, at the same time, with the rising of the mounting plate 202, the forming die 203 gradually separates from the film, while the positioning frame 3 still contacts the film under the action of the spring 304, ensuring that the film can be completely left on the conveyor belt 103 for transportation, thereby maintaining the continuity of production;

[0035] When the mounting plate 202 rises by a certain distance, the positioning frame 3 gradually separates from the film, thus completing the action process of the positioning frame 3 in a complete forming cycle, ensuring that the formed film can be completely and accurately left on the conveying mechanism, ready for the next process or collected and arranged.

[0036] Embodiment 2:

[0037] Referring to Figure 3 , Figure 4 , Figure 5 , the automatic forming machine for disposable plastic aprons is basically the same as embodiment 1, and further includes an electric telescopic rod 403 fixedly installed on the mounting plate 202, and a pull rod 402 fixedly connected to the connecting block 4 and slidably connected to the output end of the electric telescopic rod 403 through one end of the side wall of the positioning frame 3.

[0038] One end of the pull rod 402 penetrating through the side wall of the positioning frame 3 is provided with a sliding groove 404, and a sliding block 405 is slidably connected in the sliding groove 404, and the sliding block 405 is fixedly connected to the output end of the electric telescopic rod 403.

[0039] After the forming die 203 completes a forming operation and rises, the electric telescopic rod 403 is started, the electric telescopic rod 403 pushes the pull rod 402 to move, and the pull rod 402 moves by driving the brush 401 on the surface of the forming die 203 to move back and forth through the connecting block 4, which falls off the remaining plastic, prevents the accumulation of plastic from affecting the subsequent forming effect, reduces the frequency and difficulty of manual cleaning of the mold, reduces the labor intensity and maintenance cost, and ensures the good working state of the mold, which is conducive to continuous production of high-quality products. The brushed plastic falls onto the conveyor belt 103, so that it is transported with the formed film to the next process, so as to facilitate the worker to clean or collect the residual film in the next process, and when the cleaning operation is completed, the electric telescopic rod 403 returns to the initial state.

[0040] It should be noted that, by sliding the slider 405 in the sliding groove 404, when the positioning frame 3 pushes the connecting seat 301 to slide upward on the guide rod 302, the pull rod 402 will not interfere with the movement of the connecting seat 301.

[0041] Embodiment 3:

[0042] Referring to Figure 1 , Figure 2 , Figure 6 The disposable plastic apron automatic forming machine is basically the same as that in Embodiment 1, and further, the lower ends of the frame 1 are fixedly connected with support frames 503.

[0043] The two ends of the support frame 503 are inserted with screw rods 5, and the upper and lower ends of the support frame 503 are provided with nuts 502, which are threadedly connected with the screw rods 5, and the lower ends of the screw rods 5 are fixedly installed with bases 501.

[0044] At the initial stage of installation of the equipment or when the height of the equipment needs to be adjusted, a wrench or other tools are used to rotate the nuts 502, so that the screw rods 5 are raised or lowered, and after the desired height is reached, the nuts 502 are tightened to fix the screw rods 5 on the support frames 503, so that if it is found that the equipment is inclined or the height is not appropriate during the operation of the equipment, the nuts 502 and the screw rods 5 can be adjusted again to correct the situation, so that the equipment is always at a stable and appropriate working height.

[0045] The above only describes preferred embodiments of the present application and is not intended to limit the present application in any form. Although the present application has been disclosed as above with reference to the preferred embodiments, it is not intended to limit the present application.
