Description

Technical Field

[0001] The utility model relates to a blanking component, in particular to a blanking component of a bottle blowing machine, belonging to the technical field of bottle blowing machines. Background Technique

[0002] Plastic hollow containers are widely used in the beverage, pharmaceutical, cosmetic, food and chemical industries due to their light weight, low cost, high safety and other characteristics, and more manufacturers are attracted to choose plastic containers to replace the previous glass containers.

[0003] A bottle blowing machine refers to a machine for blowing bottles. The simplest explanation is a machine that can blow plastic particles (softened into a liquid) or preformed bottle blanks into bottles through certain technological means. During blanking, usually an artificial method is adopted, and the bottles are manually removed from the bottle blank seat, resulting in low work efficiency.

[0004] In the Chinese Patent Publication Specification CN218256712U, a bottle blowing machine blanking device is disclosed. The rotation cylinder two drives the gear to rotate, and then drives the rack one and the rack two to slide in the base, thereby driving the left clamping arm and the right clamping arm to move relatively to clamp the bottle, ensuring firm and stable clamping. After clamping the bottle, the cylinder two acts to drive the lifting plate to rise, removing the bottle from the bottle blank seat. The rotation cylinder one acts to drive the rotating shaft to rotate 180°, and the cylinder one drives the sliding plate to act, removing the bottle clamped by the clamping component from the annular chain area, completing the automatic blanking of the bottle blowing machine.

[0005] When the technical solution of the above patent is used for blanking, multiple steps are required. First, the cylinder one is used to make the sliding plate close to the bottle blank seat, the finished product is clamped by the clamping component, the cylinder two cooperates with the lifting plate to drive the finished product to move up, the cylinder one cooperates with the sliding plate to make the finished product away from the bottle blank seat, and the clamping component releases the finished product. It is found in actual application that the blanking of the above patent is relatively cumbersome and the blanking efficiency needs to be improved. Here, a blanking component of a bottle blowing machine is proposed. Summary of the Invention

[0006] The technical problem to be solved by the utility model is to provide a blanking component of a bottle blowing machine, which can simplify the blanking steps of the finished product and improve the blanking efficiency.

[0007] To solve the above problems, the technical solution adopted by the utility model is:

[0008] A blanking component of a bottle blowing machine includes a frame, the frame is provided with a lifting component, and a blanking mechanism is arranged on the frame.

[0009] Specifically, the lifting component includes an electric push rod, and the output end of the electric push rod is fixed to a sliding cylinder through a mounting plate.

[0010] The blanking mechanism includes a sliding seat fixed to the upper end of the frame. A sliding cylinder is slidably connected inside the sliding seat. A fixed cylinder is fixed to the lower end of the sliding cylinder. A sponge sleeve is fixed inside the fixed cylinder. A push rod is fixed to the lower end of the sliding cylinder through a mounting block.

[0011] Specifically, a sliding strip is fixed to the sliding cylinder, and a sliding groove is formed in the sliding seat. The sliding seat and the sliding cylinder are slidably connected through the sliding groove and the sliding strip.

[0012] Specifically, the inner contour of the fixed cylinder is circular, and the inner contour of the sponge sleeve is smaller than the outer contour of the bottle body.

[0013] A U-shaped cylinder is fixed to the side of the sliding seat through a mounting frame, and the left end of the U-shaped cylinder corresponds to the position of the push rod. Specifically, ventilation holes are formed in the right end of the U-shaped cylinder, and a first compression spring and a second compression spring are respectively fixed to both ends inside the U-shaped cylinder through spring seats.

[0014] The other ends of the first compression spring and the second compression spring are respectively fixed with a first piston and a second piston, and both the first piston and the second piston are slidably connected to the U-shaped cylinder. A moving rod penetrating the U-shaped cylinder is fixed to the second piston, and a guide plate is fixed to the other end of the moving rod. Specifically, the moving rod is a square rod and is in sliding contact with the U-shaped cylinder.

[0015] Specifically, two guard plates are fixed to the guide plate, and the outer contour of the guard plate is rectangular.

[0016] The blanking mechanism further includes an air pump fixed to the frame. The air pump is communicated with the inner cavity of the fixed cylinder through the sliding cylinder. In the U-shaped cylinder, a hydraulic medium is filled in the communication cavity between the first piston and the second piston.

[0017] The beneficial effects of adopting the above technical solutions are as follows:

[0018] By starting the electric push rod, the blanking component of this blow molding machine can drive the sliding cylinder, the fixed cylinder, and the sponge sleeve to approach the bottle body. After the bottle body is fixed by the sponge sleeve, reverse-start the electric push rod to drive the bottle body to rise. After the sponge sleeve moves to its original height and continues to rise, the sliding cylinder will drive the push rod to squeeze the first piston, and then push the second piston through the hydraulic medium inside the U-shaped cylinder. The second piston will drive the moving rod and the guide plate to move to the lower part of the fixed cylinder. Finally, start the air pump, and the high-pressure gas generated by the air pump is delivered to the inner cavity of the fixed cylinder, and then the bottle body fixed on the sponge sleeve is blown onto the guide plate and moved out along the direction of the guide plate to complete the blanking work. This device can realize the fixation of the bottle body and the separation of the bottle body from the bottle preform seat by starting the electric push rod, and start the air pump to complete the final collection work. The steps are relatively simple, improving the blanking efficiency. Description of the Drawings

[0028] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be clearly and completely described below in conjunction with specific embodiments.

[0029] Please refer to Figures 1 to 5 , an embodiment of the present utility model provides a feeding assembly of a blow molding machine, including a frame 1. A material collection box can also be provided on the side of the preform seat 5 opposite to this device to prevent the completed bottle body 6 from falling to the ground. The frame 1 is provided with a lifting assembly, and the lifting assembly includes an electric push rod 2. The output end of the electric push rod 2 is fixed to the sliding cylinder 302 through a mounting plate, enabling the sliding cylinder 302 to move up and down.

[0030] Please pay special attention to referring to Figure 1 , Figure 2 , Figure 3 and Figure 4, a blanking mechanism 3 is arranged on the frame 1. The blanking mechanism 3 includes a sliding seat 301 fixed to the upper end of the frame 1. A sliding cylinder 302 is slidably connected inside the sliding seat 301. A fixed cylinder 303 is fixed to the lower end of the sliding cylinder 302. A sliding strip 3021 is fixed to the sliding cylinder 302. A sliding groove 3011 is formed on the sliding seat 301. The sliding seat 301 and the sliding cylinder 302 are slidably connected through the sliding groove 3011 and the sliding strip 3021. The sliding cylinder 302 can slide on the sliding seat 301. A sponge sleeve 3031 is fixed inside the fixed cylinder 303. The inner contour of the fixed cylinder 303 is circular. The inner contour of the sponge sleeve 3031 is smaller than the outer contour of the bottle body 6. Thus, when the sponge sleeve 3031 abuts against the bottle body 6, the sponge sleeve 3031 can generate elastic deformation and fix the bottle body 6 through the elastic deformation elastic force of itself. A push rod 305 is fixed to the lower end of the sliding cylinder 302 through a mounting block.

[0031] Please refer specifically to Figure 2 、 Figure 3 and Figure 4 , a U-shaped cylinder 304 is fixed to the side surface of the sliding seat 301 through a mounting frame 3041, and the left end of the U-shaped cylinder 304 corresponds to the position of the push rod 305. When the sliding cylinder 302 drives the fixed cylinder 303 and the sponge sleeve 3031 to rise to the initial height and then continue to rise, the sliding cylinder 302 will drive the push rod 305 to push the first piston 307. The two ends inside the U-shaped cylinder 304 are respectively fixed with a first compression spring 306 and a second compression spring 308 through spring seats. The first compression spring 306 and the second compression spring 308 generate deformation respectively under the push of the first piston 307 and the second piston 309, and the elastic force generated by the deformation can drive the first piston 307 and the second compression spring 308 to reset.

[0032] The other ends of the first compression spring 306 and the second compression spring 308 are respectively fixed with a first piston 307 and a second piston 309, and both the first piston 307 and the second piston 309 are slidably connected to the U-shaped cylinder 304. There is good sealing between the first piston 307 and the U-shaped cylinder 304, and there is good sealing between the second piston 309 and the U-shaped cylinder 304. A moving rod 310 penetrating the U-shaped cylinder 304 is fixed to the second piston 309. Preferably, the moving rod 310 is a square rod. When the moving rod 310 moves under the push of the second piston 309, it will not rotate. The moving rod 310 is in sliding contact with the U-shaped cylinder 304. A ventilation hole 313 is formed at the right end of the U-shaped cylinder 304. When the second piston 309 moves inside the U-shaped cylinder 304, due to the arrangement of the ventilation hole 313, the gas inside the lower end of the U-shaped cylinder 304 will not generate resistance to the movement of the second piston 309. The other end of the moving rod 310 is fixed with a guide plate 311. Two guard plates 312 are fixed to the guide plate 311. The guard plates 312 play a role in guiding the bottle body 6. The outer contour of the guard plates 312 is rectangular.

[0033] Please refer specifically toFigure 1 , Figure 2 and Figure 3 , the blanking mechanism 3 further includes an air pump 4 fixed on the frame 1. The air pump 4 is communicated with the inner cavity of the fixed cylinder 303 through a sliding cylinder 302. In the U-shaped cylinder 304, a hydraulic medium is filled in the communication cavity between the first piston 307 and the second piston 309. After the air pump 4 is started, the high-pressure gas generated by it can be transported to the inner cavity of the sliding cylinder 302. Then the gas will act on the bottle body 6 fixed by the sponge sleeve 3031, and then the bottle body 6 fixed on the sponge sleeve 3031 will be blown off. The blown-off bottle body 6 will fall into the material collection box along the direction of the guide plate 311.

[0034] Working principle: When in use, first start the electric push rod 2. The electric push rod 2 can drive the sliding cylinder 302, the fixed cylinder 303, and the sponge sleeve 3031 to move downward. The sponge sleeve 3031 gradually approaches the bottle body 6. The sponge sleeve 3031 can undergo elastic deformation. The bottle body 6 is inserted into the sponge sleeve 3031. The elastic force generated by the self-deformation of the sponge sleeve 3031 can fix the bottle body 6 in the sponge sleeve 3031. After the bottle body 6 is fixed through the sponge sleeve 3031, reverse-start the electric push rod 2 to drive the bottle body 6 to rise. After the sponge sleeve 3031 moves to its original height and continues to rise, at this time, the sliding cylinder 302 will drive the push rod 305 to squeeze the first piston 307, causing the first piston 307 to deform. The hydraulic medium inside the U-shaped cylinder 304 is pushed by the first piston 307 to push the second piston 309, and the second piston 309 will drive the moving rod 310, the guide plate 311, and the guard plate 312 to move to the lower part of the fixed cylinder 303.

[0035] After the sponge sleeve 3031 moves to its original height, the sliding cylinder 302 continues to rise. During this process, the sliding cylinder 302 gradually drives the push rod 305, the fixed cylinder 303, the sponge sleeve 3031, and the bottle body 6 to rise. The second piston 309 gradually pushes the moving rod 310, the guide plate 311, and the guard plate 312 towards the bottom of the bottle body 6. During this process, the guide plate 311 and the guard plate 312 will not collide with the rising bottle body 6.

[0036] After the moving rod 310, the moving rod 310, and the guard plate 312 move to the bottom of the bottle body 6, start the air pump 4. The high-pressure gas generated by the air pump 4 is transported to the inner cavity of the fixed cylinder 303, and then the bottle body 6 fixed on the sponge sleeve 3031 is blown onto the guide plate 311 and moves out along the direction of the guide plate 311, completing the blanking work. This device can realize two steps of fixing the bottle body 6 and detaching the bottle body 6 from the bottle blank seat 5 by starting the electric push rod 2, and can complete the final collection work by starting the air pump 4. The steps are relatively simple, improving the blanking efficiency.

[0037] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
