Description

Technical Field

[0001] This utility model belongs to the field of blow molding machine equipment, specifically a blow molding machine bottle anti-scratch mechanism. Background Technology

[0002] A blow molding machine is a specialized machine for manufacturing plastic bottles. It is highly efficient and automated, and can mass-produce plastic bottles of various shapes and sizes. Therefore, it is widely used in the food, beverage, cosmetics, and pharmaceutical industries.

[0003] The working principle of a blow molding machine is to place a heated plastic preform (also known as a preform) into a mold, and then blow air to make the preform expand and fit against the inner wall of the mold, and finally cool and solidify into the desired plastic bottle.

[0004] Through long-term use and observation, it was found that during the blow molding process of bottles using a blow molding machine, dust adhering to the bottle body would rub against the bottle surface, thereby increasing the risk of the bottle surface being scratched.

[0005] Therefore, this utility model provides a scratch-resistant mechanism for blow molding bottle bodies. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art and solve at least one of the problems mentioned in the background art, a blow molding bottle anti-scratch mechanism is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A blow molding machine bottle anti-scratch mechanism, comprising a worktable; a top seat fixed to the top of the worktable; a plurality of first electric push rods fixedly connected to the top of the top seat; a blow molding machine assembled at the output end of each of the first electric push rods; a fixing component provided in the middle of the side wall of the worktable, which can fix and clean the bottle; the fixing component and the blow molding machine are correspondingly arranged; a support seat fixed to the middle of the side wall of the worktable; a conveyor seat installed on the top of the support seat; a buffer component provided in the middle of the side wall of the conveyor seat, which can reduce the moving speed of the bottle; a motor assembled in the middle of the side wall of the conveyor seat; a conveyor belt fixedly connected to the output end of the motor; the conveyor belt rotating inside the conveyor seat; a pushing component provided on the top of the worktable, which can push the blown bottle from the worktable onto the conveyor belt; guide components provided on both sides of the conveyor seat, which can adjust the moving direction of the bottle; the fixing component includes a pair of second electric push rods; a pair of... The second electric actuator is symmetrically assembled on the side wall of the workbench; a clamp is fixedly connected to the output end of the second electric actuator; a fixing airbag is fixed in the middle of the side wall of the clamp; the fixing airbag is made of elastic material; an air extraction pipe is fixedly connected to the middle of the side wall of the fixing airbag; multiple suction pipes are fixedly connected to the bottom of the fixing airbag; the fixing airbag, air extraction pipe, and suction pipe are all hollow and interconnected; this step, by setting the second electric actuator, clamp, and fixing airbag, can fix the bottle being blown, helping to prevent the bottle from collapsing during the blowing process. To prevent molding defects caused by bottle shaking, such as uneven wall thickness and distorted shape, this system reduces scrap and rework rates, lowers production costs, and stabilizes the bottle's relative position to the blow molding machine. This helps prevent friction between the bottle and the machine's edges or other parts during blow molding, thus reducing scratches. By installing a fixing airbag, suction pipe, and dust suction pipe, dust adhering to the bottle can be cleaned, reducing the risk of dust rubbing against the blow molding machine or other parts during blow molding, which would exacerbate the risk of scratches on the bottle.

[0008] Preferably, the pushing assembly includes a fixing plate; the fixing plate is fixed to the top of the workbench; a third electric push rod is assembled in the middle of the side wall of the fixing plate; a push plate is fixedly connected to the output end of the third electric push rod; an elastic pad is installed in the middle of the side wall of the push plate; the elastic pad is made of elastic material; this step, by setting the fixing plate, the third electric push rod and the push plate, can quickly and accurately remove the blow-molded bottle from the workbench and push it onto the conveyor belt, which helps to maintain the continuous operation of the production line, reduces downtime and waiting time, thereby improving the overall production efficiency. Moreover, this setting can maintain stable force and speed during the bottle pushing process, reducing the generation of scratches and defects. The elastic pad can reduce the impact force on the bottle and reduce the damage or scratches caused by direct collision between the bottle and the push plate.

[0009] Preferably, the buffer assembly includes a fixing rod; the fixing rod is fixed to the side wall of the conveyor seat; a buffer plate is rotatably connected to the middle of the side wall of the fixing rod; a first buffer pad is assembled in the middle of the side wall of the buffer plate; the first buffer pad is made of elastic material; this step, by setting the fixing rod, buffer plate and first buffer pad, can effectively absorb the impact force generated by the buffer plate on the bottle, reduce the instantaneous pressure on the bottle during the pushing process, thereby reducing the damage or deformation of the bottle caused by excessive impact force. At the same time, this setting can reduce the accumulation or misalignment of bottles caused by pushing too fast or too slow, thereby ensuring that the bottles are neatly arranged on the conveyor belt.

[0010] Preferably, the guide assembly includes multiple springs; the springs are fixed to the side wall of the conveyor seat; a guide pad is fixed to the other end of the spring; the guide pad is made of elastic material; this step, by setting the springs and guide pads, can limit the range of movement of the bottle on the conveyor belt, prevent the bottle from deviating due to external force, and make the bottle stably transported along the predetermined path.

[0011] Preferably, a second buffer pad is installed on the top of the workbench; the second buffer pad is made of elastic material; during the blow molding process, high-pressure gas causes the preform to expand rapidly and form, which generates a large impact force. This step, by setting a second buffer pad under the blow molding machine, can absorb and disperse these impact forces, making the bottle bottom more evenly stressed and reducing the possibility of scratches.

[0012] Preferably, a sealing ring is fitted in the middle of the side wall of the blow molding machine; the sealing ring is made of elastic material; this step provides a sealing effect by setting the sealing ring, so that the high-pressure gas during the blow molding process will not leak from the blow nozzle and the bottle.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The anti-scratch mechanism for blow molding bottles described in this utility model, by setting a second electric push rod, a clamping plate, and a fixing airbag, can fix the bottle being blown, which helps to prevent poor molding caused by bottle shaking during the blowing process, such as uneven wall thickness and shape distortion, thereby reducing scrap rate and rework rate, and lowering production costs. Moreover, after the bottle is fixed, its relative position with the blow molding machine is stabilized, which helps to prevent the bottle from rubbing against the edge or other parts of the blow molding machine during the blow molding process, thereby reducing scratches. By setting a fixing airbag, an air extraction pipe, and a dust suction pipe, dust adhering to the bottle can be cleaned, reducing the risk of dust rubbing against the blow molding machine or other parts during the blow molding process, thereby reducing the risk of scratches on the bottle.

[0015] 2. The blow molding bottle anti-scratch mechanism described in this utility model, by setting a fixed plate, a third electric push rod and a push plate, can quickly and accurately take the blow-molded bottle out of the worktable and push it onto the conveyor belt, which helps to maintain the continuous operation of the production line, reduce downtime and waiting time, thereby improving the overall production efficiency. Moreover, this setting can maintain stable force and speed during the bottle pushing process, reducing the generation of scratches and defects. The elastic pad can reduce the impact force on the bottle and reduce the direct collision between the bottle body and the push plate, thus reducing damage or scratches. Attached Figure Description

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 4As shown, an embodiment of the present invention provides a bottle anti-scratch mechanism for a blow molding machine, comprising a workbench 1; a top seat 11 fixed to the top of the workbench 1; a plurality of first electric push rods 12 fixedly connected to the top of the top seat 11; a blow molding machine 13 assembled at the output end of the first electric push rods 12; a fixing component provided in the middle of the side wall of the workbench 1, which can fix and clean the bottle; the fixing component and the blow molding machine 13 are correspondingly arranged; a support seat 14 fixed to the middle of the side wall of the workbench 1; a conveyor seat 15 installed on the top of the support seat 14; a buffer component provided in the middle of the side wall of the conveyor seat 15, which can reduce the moving speed of the bottle; a motor 16 assembled in the middle of the side wall of the conveyor seat 15; a conveyor belt 17 fixedly connected to the output end of the motor 16; the conveyor belt 17 rotates inside the conveyor seat 15; a pushing component provided on the top of the workbench 1, which can push the blown bottle from the workbench 1 onto the conveyor belt 17; and guide components provided on both sides of the conveyor seat 15. The guide component can adjust the direction of bottle movement. During operation, the operator uses the fixing component to fix multiple bottles to be blown, with the bottle mouth aligned with the bottom of the blow molding machine 13. Then, multiple first electric push rods 12 are activated, which push the blow molding machine 13 downward until it is embedded inside the bottle mouth. The blow molding machine 13 is then activated again, blowing air into the bottle to inflate it. Once the bottle is formed, the blow molding machine 13 is stopped and removed. The fixing component is then activated, releasing the bottle, which falls onto the top of the workbench 1. The operator then activates the pushing component, which pushes the bottle to the top of the conveyor belt 17. Simultaneously, the motor 16 is activated, which drives the conveyor belt 17 to rotate inside the conveyor seat 15. When the bottle moves to the top of the conveyor belt 17, the buffer component slows it down, and the guide component guides the bottle to move along the central area of ​​the conveyor belt 17.

[0026] like Figures 1 to 4As shown, the fixing assembly includes a pair of second electric actuators 2; the pair of second electric actuators 2 are symmetrically assembled on the side wall of the workbench 1; a clamping plate 21 is fixedly connected to the output end of the second electric actuator 2; a fixing airbag 22 is fixed in the middle of the side wall of the clamping plate 21; the fixing airbag 22 is made of elastic material; an air extraction pipe 23 is fixedly connected to the middle of the side wall of the fixing airbag 22; multiple suction pipes 24 are fixedly connected to the bottom of the fixing airbag 22; the fixing airbag 22, the air extraction pipe 23, and the suction pipes 24 are all hollow and interconnected; during operation, the working... Personnel place multiple bottles between a pair of retaining airbags 22, then activate the second electric actuator 2. The second electric actuator 2 moves the clamping plate 21, which in turn moves the retaining airbags 22 synchronously. At this point, the pair of retaining airbags 22 clamp the bottles from both sides. Then, the personnel connect the suction pipe 23 to the vacuum pump. Because the retaining airbags 22, suction pipe 23, and suction pipe 24 are connected, the airflow will draw dust adhering to the bottle surface into the retaining airbags through the multiple suction pipes 24. Inside the bladder 22, multiple first electric push rods 12 are then activated. The first electric push rods 12 push the blow molding machine 13 downward. After the blow molding machine 13 is embedded in the bottle, it is activated and begins to blow air into the bottle. At this time, the bottle gradually expands and squeezes the fixed air bladder 22. This step, by setting the second electric push rod 2, clamp 21 and fixed air bladder 22, can fix the bottle being blown, which helps to prevent poor molding caused by bottle shaking during the blowing process, such as uneven wall thickness, shape distortion and other problems, reducing scrap rate and rework rate, and lowering production costs. Moreover, after the bottle is fixed, its relative position with the blow molding machine 13 is stable, which helps to prevent the bottle from rubbing against the edge or other parts of the blow molding machine 13 during the blow molding process, thereby reducing scratches. By setting the fixed air bladder 22, suction pipe 23 and dust suction pipe 24, the dust adhering to the bottle can be cleaned, reducing the friction between dust and the blow molding machine 13 or other parts during the blow molding process, thereby reducing the risk of scratching the bottle.

[0027] like Figures 1 to 4As shown, the feeding assembly includes a fixed plate 3; the fixed plate 3 is fixed to the top of the workbench 1; a third electric push rod 31 is mounted on the middle of the side wall of the fixed plate 3; a push plate 32 is fixedly connected to the output end of the third electric push rod 31; an elastic pad 33 is installed on the middle of the side wall of the push plate 32; the elastic pad 33 is made of elastic material; after the bottle is formed, it will fall onto the top of the workbench 1. When the third electric push rod 31 is activated, it will push the push plate 32 to move. At this time, the push plate 32 will drive the elastic pad 33 to move synchronously. When the elastic pad 33 contacts the bottle, it will push the bottle towards the conveyor. The conveyor belt 17 moves quickly and accurately by setting up the fixed plate 3, the third electric push rod 31 and the push plate 32 to remove the blow-molded bottles from the workbench 1 and push them onto the conveyor belt 17. This helps to maintain the continuous operation of the production line, reduce downtime and waiting time, and thus improve overall production efficiency. This setting can maintain stable force and speed during the bottle pushing process, reducing the generation of scratches and defects. The elastic pad 33 can reduce the impact force on the bottle and reduce the direct collision between the bottle and the push plate 32, thus reducing damage or scratches.

[0028] like Figure 1 and Figure 2 As shown, the buffer assembly includes a fixed rod 4; the fixed rod 4 is fixed to the side wall of the conveyor seat 15; a buffer plate 41 is rotatably connected to the middle of the side wall of the fixed rod 4; a first buffer pad 42 is assembled in the middle of the side wall of the buffer plate 41; the first buffer pad 42 is made of elastic material; during operation, the bottle will contact and squeeze the first buffer pad 42 during the movement process. At this time, the first buffer pad 42 will drive the buffer plate 41 to rotate on the fixed rod 4, so that the bottle passes through the first buffer pad 42 and moves to the top of the conveyor belt 17 after deceleration. This step, by setting the fixed rod 4, the buffer plate 41 and the first buffer pad 42, can effectively absorb the impact force generated by the buffer plate 41 on the bottle, reduce the instantaneous pressure on the bottle during the pushing process, thereby reducing the damage or deformation of the bottle caused by excessive impact force. At the same time, this setting can reduce the accumulation or misalignment of the bottle caused by pushing too fast or too slow, thereby ensuring that the bottle is neatly arranged on the conveyor belt 17.

[0029] like Figure 1 and Figure 2 As shown, the guide assembly includes multiple springs 5; the springs 5 ​​are fixed to the side wall of the conveyor seat 15; the other end of the spring 5 is fixed to a guide pad 51; the guide pad 51 is made of elastic material; during operation, the bottle moves onto the conveyor belt 17 and is moved by the conveyor belt 17. When the bottle comes into contact with the guide pads 51 on both sides of the conveyor belt 17, it will return to the center area of ​​the conveyor belt 17 under the rebound action of the spring 5. This step, by setting the springs 5 ​​and the guide pads 51, can limit the range of movement of the bottle on the conveyor belt 17, prevent the bottle from deviating due to external force, and make the bottle stably transported along the predetermined path.

[0030] like Figure 4 As shown, a second buffer pad 6 is installed on the top of the workbench 1; the second buffer pad 6 is made of elastic material; during the blow molding process, the high-pressure gas causes the preform to expand rapidly and form, which generates a large impact force. This step can absorb and disperse these impact forces by setting the second buffer pad 6 under the blow molding machine 13, making the bottle bottom more evenly stressed and reducing the possibility of scratches.

[0031] like Figure 4 As shown, a sealing ring 7 is fitted in the middle of the side wall of the blow molding machine 13; the sealing ring 7 is made of elastic material; this step provides a sealing effect by setting the sealing ring 7, so that the high-pressure gas during the blow molding process will not leak from the blow head and the bottle.

[0032] Working principle: The operator uses a fixing component to secure multiple bottles to be inflated, with the bottle openings aligned directly below the blow molding machine 13. Then, multiple first electric actuators 12 are activated, pushing the blow molding machine 13 downwards until it is embedded inside the bottle opening. The blow molding machine 13 is then activated again, blowing air into the bottle, causing it to expand. Once the bottle is formed, the blow molding machine 13 is stopped and removed. The fixing component is then activated, releasing the bottle, which falls onto the top of the worktable 1. The operator then activates the pushing component, which pushes the bottle onto the conveyor belt. At the top of 17, motor 16 is started simultaneously. Motor 16 drives conveyor belt 17 to rotate inside conveyor seat 15. When the bottle moves to the top of conveyor belt 17, the buffer component slows it down, and the guide component guides the bottle to move along the central area of ​​conveyor belt 17. The operator places multiple bottles between a pair of fixed airbags 22, and then starts the second electric push rod 2. The second electric push rod 2 moves clamping plate 21. When clamping plate 21 moves, it moves fixed airbags 22 synchronously. At this time, a pair of fixed airbags 22 clamp the bottle from both sides. Then the operator connects the suction pipe 23 and the vacuum tube. The pump is connected because the fixed airbag 22, the suction pipe 23, and the dust suction pipe 24 are connected. At this time, the airflow will draw the dust adhering to the surface of the bottle into the fixed airbag 22 through multiple dust suction pipes 24. Then, multiple first electric push rods 12 are activated, which will push the blow molding machine 13 to move down. After the blow molding machine 13 is embedded in the bottle, it is activated and starts blowing air into the bottle. At this time, the bottle gradually expands and squeezes the fixed airbag 22. After the bottle is formed, it will fall to the top of the workbench 1. The third electric push rod 31 is activated, which will push the push plate 32 to move. At this time, the push plate 32 will carry... The dynamic elastic pad 33 moves synchronously. When the elastic pad 33 contacts the bottle, it will push the bottle towards the conveyor belt 17. During the movement, the bottle will contact and squeeze the first buffer pad 42. At this time, the first buffer pad 42 will drive the buffer plate 41 to rotate on the fixed rod 4, so that the bottle will pass through the first buffer pad 42 after deceleration and move to the top of the conveyor belt 17. The bottle will be carried by the conveyor belt 17 when it moves onto the conveyor belt 17. When the bottle contacts the guide pads 51 on both sides of the conveyor belt 17, it will return to the center area of ​​the conveyor belt 17 under the rebound action of the spring 5.
