Description

Technical Field

[0001] This invention belongs to the technical field of blow molding machine equipment, specifically a fully automatic manual mold entry device for blow molding machines. Background Technology

[0002] In the modern container manufacturing industry, the demand for hollow products with handles (such as large-capacity water tanks and chemical drums) is increasing. In traditional blow molding processes, handle installation mostly relies on manual labor or semi-automatic robotic arms, which has inherent drawbacks such as low efficiency, poor positioning accuracy, and unstable product yield. In existing technologies, handles usually need to be pre-molded by injection molding and then picked up manually or by simple machinery and inserted into the pre-set slots in the blow molding mold. This process is susceptible to human error, which can cause the handle to twist, shift, or even fall off during high-pressure blow molding, seriously affecting the structural strength and appearance quality of the bottle.

[0003] However, in common blow molding machines, the processes of gripping, installing, blowing, and unloading require multiple machines to work together, resulting in large equipment footprints and inconsistent overall equipment coordination, leading to low production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic manual mold entry device for a blow molding machine in order to solve the problems mentioned above.

[0005] The technical solution adopted in this invention is as follows: A fully automatic handle-entering mold device for a blow molding machine includes a frame, the frame being a ring structure, a through sliding groove being provided on the upper part of the frame, a preform mounting cap for carrying preforms being slidably installed in the sliding groove, and a heating plate, a handle mounting cylinder, a handle mounting assembly, a drive shaft of a built-in motor, a left mold fixing plate, a right mold fixing plate, and a collection box being arranged sequentially along the moving direction of the preform mounting cap.

[0006] By adopting the above technical solution, during the operation of the equipment, the rotating shaft of the built-in motor drives the transmission belt to move, thereby moving the fixed block. When the fixed block moves to below the handle mounting cylinder, the drive clamping motor is started, driving the bidirectional lead screw to rotate, thereby causing the clamping plate to clamp the handle inside the handle mounting cylinder. The lifting cylinder retracts, causing the handle to descend and be fitted onto the preform placed on the preform mounting cap. The drive shaft of the built-in motor drives the bottom of the preform mounting cap to rotate in the same direction as the transmission belt through the drive belt and the drive groove on the outside of the drive belt. After the right mold and left mold stop, the preform is formed after mold closing and compression. It moves again, and the lifting cylinder at the transmission shaft rises, causing the formed bottle body and handle to rise and detach from the preform mounting cap. At the same time, the drive clamping motor reverses, causing the clamping plate to release the handle, allowing the bottle body and handle to fall into the collection box. Through this structure, the clamping, fitting, blow molding, unloading and collection of the handle are integrated, making the equipment structure more compact and improving the product processing efficiency.

[0007] In a preferred embodiment, the handle mounting assembly includes a rotating shaft with a built-in motor, a drive shaft, a drive belt, a fixing block, a lifting cylinder, a mounting plate, a C-shaped fixing bracket, a two-way lead screw, a drive clamping motor, and a clamping plate; wherein The rotating shaft and transmission shaft of the built-in motor are respectively positioned above the frame along the moving direction of the preform mounting cap. A transmission belt is fitted around the outer side of the rotating shaft and transmission shaft of the built-in motor. Evenly distributed fixing blocks are provided on the outer side of the transmission belt. A lifting cylinder is fixedly connected above the fixing blocks. A mounting plate is fixedly installed above the lifting cylinder. A C-shaped fixing frame is installed in front of the mounting plate. A drive clamping motor is fixedly connected to the side of the C-shaped fixing frame. The output end of the drive clamping motor passes through the C-shaped fixing frame and extends to the inner side of the C-shaped fixing frame, where a double-acting screw is fixedly connected. A clamping plate is threaded onto the outer side of the double-acting screw.

[0008] By adopting the above technical solution, the handle is gripped by controlling the lifting cylinder to rise, and then the bottle preform is lowered and fitted onto the preform mounting cap. The preform is molded and formed by the movement of the transmission belt, and the bottle body is separated from the preform mounting cap by raising the mounting plate, thereby improving the production efficiency of the equipment.

[0009] In a preferred embodiment, two drive shafts of built-in motors are fixedly arranged below the frame. The two drive shafts of built-in motors are arranged parallel to each other along the movement direction of the preform mounting cap. A drive belt is sleeved on the outer side of the two drive shafts of built-in motors. A drive groove matching the size of the preform mounting cap is opened on the outer side of the drive belt.

[0010] By adopting the above technical solution, the drive belt is driven to rotate by the drive shaft of the built-in motor, and the drive groove opened on the outside of the drive belt engages with the bottom of the preform mounting cap in the sliding groove, thereby driving the preform mounting cap inside the sliding groove to move.

[0011] In a preferred embodiment, an upper limit plate and a lower limit plate are fixedly connected to the upper and lower parts of the preform mounting cap, respectively, and the upper limit plate and the lower limit plate are located at the upper and lower parts of the frame, respectively.

[0012] By adopting the above technical solution, and by setting an upper limit plate and a lower limit plate on the outside of the preform mounting cap, the preform mounting cap can be prevented from falling off, thus ensuring the stable operation of the equipment.

[0013] In a preferred embodiment, the left mold fixing plate and the right mold fixing plate are located on both sides of the frame, and the inner sides of the left mold fixing plate and the right mold fixing plate are respectively provided with corresponding left molds and right molds.

[0014] By adopting the above technical solution, and by installing openable right and left molds on the inner sides of the left mold fixing plate and the right mold fixing plate, the preform can be formed.

[0015] In a preferred embodiment, a handle mounting cylinder is provided on the front side of the heating plate, and a handle is placed on the inner side of the handle mounting cylinder.

[0016] By adopting the above technical solution, and by setting the handle mounting cylinder on the front side of the handle mounting cylinder, the handle can be easily installed, ensuring the stable operation of the equipment.

[0017] In a preferred embodiment, two heating plates are provided, and the two heating plates are symmetrically arranged about the axis of the sliding groove, and a heating wire is fixedly connected to the inner side of the heating plate.

[0018] By adopting the above technical solution, the preform can be heated by the heating wire on the inside of the heating plate, which facilitates the preform molding.

[0019] In a preferred embodiment, a collection box is fixedly connected to the side of the frame, and the collection box is axially aligned with the handle mounting assembly.

[0020] By adopting the above technical solution and setting up collection boxes, it is convenient to collect the bottles that have completed their shaping.

[0021] In a preferred embodiment, a guide post parallel to the bidirectional lead screw is also installed inside the C-shaped fixing frame, and a clamping plate is slidably connected to the outside of the guide post.

[0022] By adopting the above technical solution, the clamping plate can be moved on the guide post by a two-way lead screw, which can ensure the stability of the handle clamping and installation.

[0023] In a preferred embodiment, a through hole is provided at the central axis of the preform mounting cap.

[0024] By adopting the above technical solution, the through hole opened inside the preform mounting cap can facilitate blowing into the preform, ensuring the formation of the bottle body.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: During operation, the built-in motor's rotating shaft drives the transmission belt, which in turn moves the fixed block. When the fixed block moves below the handle mounting cylinder, the drive clamping motor is activated, causing the bidirectional lead screw to rotate. This causes the clamping plate to grip the handle inside the handle mounting cylinder. The lifting cylinder retracts, lowering the handle to fit onto the preform placed on the preform mounting cap. The built-in motor's drive shaft, through the drive belt and the drive groove on the outside of the drive belt, causes the bottom of the preform mounting cap to rotate in the same direction as the transmission belt. After stopping at the right and left molds and compressing the mold, the preform is formed. It then moves again, and the lifting cylinder at the transmission shaft raises, causing the formed bottle body and handle to rise and detach from the preform mounting cap. Simultaneously, the drive clamping motor reverses, causing the clamping plate to release the handle, allowing the bottle body and handle to fall into the collection box. This structure integrates handle gripping, mounting, blow molding, and unloading collection, making the equipment more compact and improving product processing efficiency.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0029] Reference Figure 1-6 A fully automatic handle-feeding mold device for a blow molding machine includes a frame 1, which is a ring structure. A through sliding groove 2 is provided on the top of the frame 1. A preform mounting cap 3 for carrying preforms is slidably installed in the sliding groove 2. A heating plate 14, a handle mounting cylinder 17, a handle mounting assembly 6, a drive shaft 7 of a built-in motor, a left mold fixing plate 10, a right mold fixing plate 11, and a collection box 16 are arranged sequentially along the moving direction of the preform mounting cap 3.

[0030] During operation, the rotating shaft 601 of the built-in motor drives the transmission belt 603 to move, thereby moving the fixing block 604. When the fixing block 604 moves below the handle mounting cylinder 17, the drive clamping motor 609 is activated, driving the bidirectional lead screw 608 to rotate, thereby causing the clamping plate 6010 to clamp the handle inside the handle mounting cylinder 17. The lifting cylinder 605 retracts, causing the handle to descend and be placed on the preform mounting cap 3. The drive shaft 7 of the built-in motor drives the bottom of the preform mounting cap 3 through the drive belt 8 and the drive groove 9 on the outside of the drive belt 8. The part rotates in the same direction as the transmission belt 603. After stopping at the right mold 12 and the left mold 13, the preform is formed after mold closing and compression. It moves again and is raised by the lifting cylinder 605 at the transmission shaft 602, which drives the formed bottle body and handle to rise and detach from the bottle preform mounting cap 3. At the same time, the clamping motor 609 is driven to reverse, causing the clamping plate 6010 to release the handle, so that the bottle body and handle fall into the collection box 16. Through the design of this structure, the clamping, mounting, blow molding and unloading collection of the handle are integrated, making the equipment structure more compact and improving the processing efficiency of the product.

[0031] The handle mounting assembly 6 includes a rotating shaft 601 with a built-in motor, a drive shaft 602, a drive belt 603, a fixing block 604, a lifting cylinder 605, a mounting plate 606, a C-shaped fixing bracket 607, a two-way lead screw 608, a drive clamping motor 609, and a clamping plate 6010; wherein The rotating shaft 601 and the transmission shaft 602 of the built-in motor are respectively arranged above the frame 1 along the moving direction of the preform mounting cap 3. The outer sides of the rotating shaft 601 and the transmission shaft 602 of the built-in motor are jointly fitted with a transmission belt 603. The outer side of the transmission belt 603 is provided with evenly distributed fixing blocks 604. A lifting cylinder 605 is fixedly connected above the fixing block 604. A mounting plate 606 is fixedly installed above the lifting cylinder 605. A C-shaped fixing frame 607 is installed in front of the mounting plate 606. A drive clamping motor 609 is fixedly connected to the side of the C-shaped fixing frame 607. The output end of the drive clamping motor 609 passes through the C-shaped fixing frame 607 and extends to the inner side of the C-shaped fixing frame 607. A double-acting screw 608 is fixedly connected to the inner side of the C-shaped fixing frame 607. A clamping plate 6010 is threadedly connected to the outer side of the double-acting screw 608.

[0032] By controlling the lifting cylinder 605 to raise, the handle is gripped and then lowered to fit the preform onto the preform mounting cap 3. The preform is molded and formed by the movement of the transmission belt 603. Finally, the bottle body is separated from the preform mounting cap 3 by the raising of the mounting plate 606, thus improving the production efficiency of the equipment.

[0033] Two drive shafts 7 with built-in motors are fixedly installed at the bottom of the frame 1. The two drive shafts 7 are parallel to the direction of movement of the preform mounting cap 3. A drive belt 8 is fitted on the outer side of the two drive shafts 7. The outer side of the drive belt 8 has a drive groove 9 that matches the size of the preform mounting cap 3. The drive belt 8 is driven to rotate by the drive shafts 7 of the built-in motors. The drive groove 9 on the outer side of the drive belt 8 engages with the bottom of the preform mounting cap 3 in the sliding groove 2, thereby driving the preform mounting cap 3 to move inside the sliding groove 2.

[0034] An upper limit plate 4 and a lower limit plate 5 are fixedly connected to the upper and lower parts of the preform mounting cap 3, respectively. The upper limit plate 4 and the lower limit plate 5 are located at the upper and lower parts of the frame 1, respectively. By setting the upper limit plate 4 and the lower limit plate 5 on the outside of the preform mounting cap 3, the preform mounting cap 3 can be prevented from falling off, ensuring the stable operation of the equipment.

[0035] The left mold fixing plate 10 and the right mold fixing plate 11 are located on both sides of the frame 1, and the left mold 13 and the right mold 12 are respectively provided on the inner side of the left mold fixing plate 10 and the right mold fixing plate 11. By installing the openable right mold 12 and the left mold 13 on the inner side of the left mold fixing plate 10 and the right mold fixing plate 11, the preform can be formed.

[0036] A handle mounting sleeve 17 is provided on the front side of the heating plate 14, and a handle is placed on the inner side of the handle mounting sleeve 17. By providing a handle mounting sleeve 17 on the front side of the handle mounting sleeve 17, it is convenient to install the handle and ensure the stable operation of the equipment.

[0037] Two heating plates 14 are provided, and the two heating plates 14 are symmetrically arranged about the axis of the sliding groove 2. Heating wires 15 are fixedly connected to the inner side of the heating plates 14. The preforms passing through can be heated by the heating wires 15 on the inner side of the heating plates 14, which facilitates the preforms to be molded and formed.

[0038] A collection box 16 is fixedly connected to the side of the frame 1, and the collection box 16 is axially aligned with the handle mounting assembly 6. By setting up the collection box 16, it is convenient to collect the shaped bottles.

[0039] The C-type fixing bracket 607 also has a guide post parallel to the bidirectional lead screw 608, and a clamping plate 6010 is slidably connected to the outside of the guide post. The bidirectional lead screw 608 drives the clamping plate 6010 to move on the guide post, which can ensure the stability of the handle gripping and installation.

[0040] A through hole is provided at the central axis of the preform mounting cap 3. The through hole in the preform mounting cap 3 facilitates the blowing of the preform into the bottle, ensuring the formation of the bottle body.

[0041] The implementation principle of the fully automatic handle entry device for a blow molding machine of the present invention is as follows: First, the preform is placed on the preform mounting cap 3. The drive belt 8 is driven by the drive shaft 7 of the built-in motor, and the preform mounting cap 3 moves in the sliding groove 2 through the drive belt 8.

[0042] When the preform is installed on the preform mounting cap 3 and passes inside the heating plate 14, the preform is heated by the heating wire 15. When the preform mounting cap 3 engages with the drive groove 9 on the drive belt 8, the clamping plate 6010 is located at the opening of the drive shaft 7 of the built-in motor. The drive clamping motor 609 is started, which drives the bidirectional lead screw 608 and drives the clamping plate 6010 to clamp the handle. Then the lifting cylinder 605 drives the handle to descend and be sleeved on the preform mounting cap 3.

[0043] When the bottle preform passes through the left mold fixing plate 10 and the right mold fixing plate 11, the right mold 12 and the left mold 13 close together, and the bottle preform is blown up through the through hole opened on the preform mounting cap 3 to form the bottle preform.

[0044] When passing through the drive shaft 602, the lifting cylinder 605 rises, and through the handle, it drives the formed bottle body to detach from the preform mounting cap 3. Then, by releasing the handle through the clamp plate 6010, the bottle body falls into the collection box 16.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
