Description

Technical Field

[0001] This application relates to the field of blow molding machine technology, and in particular to a blow molding machine feeding device. Background Technology

[0002] A blow molding machine is a device used to manufacture hollow plastic products. Its working principle is to heat and melt thermoplastic raw materials, and then form a tubular preform by extrusion or injection. High-pressure gas is then injected into the preform to make it expand and adhere tightly to the inner wall of the mold. After cooling and solidification, the desired plastic product, such as bottles, buckets, and toys, is obtained.

[0003] Plastic pellets are typically stored in bags. When feeding them into a blow molding machine, the bags usually need to be opened, and the pellets poured into the machine. Once the pellets are used up, another bag needs to be moved to the machine, cut open, and fed again. This feeding process is cumbersome and labor-intensive. Utility Model Content

[0004] The purpose of this application is to provide a feeding device for a blow molding machine that can feed multiple bags of plastic particles at once, without having to move a bag for feeding each time. The feeding process is simple and the labor cost is low.

[0005] The present application provides a feeding device for a blow molding machine, which adopts the following technical solution: A feeding device for a blow molding machine, comprising: A feeding hopper, used to connect to a blow molding machine, with an open top; A first linear guide rail is provided on one side of the feeding hopper and a platform is fixed at the output end. The first linear guide rail is used to drive the platform to move in the vertical direction. The platform is used to carry multiple bags of stacked plastic particles. A push plate is slidably disposed at the top of the first linear guide rail and is used to push a single package of plastic particles into the feeding hopper. A cutting blade is installed inside the hopper and is used to cut open single packages of plastic particles inside the hopper.

[0006] Optionally, the two ends of the cutting blade are fixed to the two symmetrical inner walls of the feeding hopper and located in the middle of the feeding hopper.

[0007] Optionally, it also includes a pressure plate and a first telescopic member, the pressure plate being located above the feeding hopper, and the first telescopic member being connected to the pressure plate and used to drive the pressure plate to move closer to the cutting blade.

[0008] Optionally, it also includes an insert plate and a second telescopic member. The insert plate is disposed on one side of the cutting blade and can fit against the cutting blade. The second telescopic member is connected to the insert plate and is used to drive the insert plate to move away from or towards the cutting blade.

[0009] Optionally, the insert plate is provided on both sides of the cutting blade.

[0010] Optionally, a two-dimensional moving platform is also included. The output end of the two-dimensional moving platform is fixed with a mounting plate, and a clamp is provided on the mounting plate. The two-dimensional moving platform is used to drive the clamp to move towards or away from the cutting blade. The clamp is used to clamp the packaging bag containing the plastic particles.

[0011] Optionally, at least one pair of clamps is provided, with the pair of clamps located at both ends of the cutting blade.

[0012] This application, through the setting of a first linear guide rail and platform, can place multiple bags of plastic granules at once, and feed one bag of plastic granules by a push plate and cut the packaging bag by a cutting blade, thus realizing the feeding of plastic granules. The feeding process only requires placing multiple bags of plastic granules on the platform at once, making the feeding process simple and convenient, optimizing the feeding process, and reducing labor costs.

[0013] Furthermore, this application uses clamps to clamp both ends of the packaging bag, allowing both ends of the packaging bag to tilt upwards, thereby reducing the residue of plastic particles at both ends of the packaging bag and avoiding waste of plastic particles.

Detailed Implementation

[0018] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0019] A feeding device for a blow molding machine, as described in the following description. Figure 1 and Figure 2The system includes a feeding hopper 1, a first linear guide rail 2, a push plate 3, and a cutting blade 4. The feeding hopper 1 is installed on the blow molding machine and has an open top. Plastic particles enter the feeding hopper 1 from above and flow into the blow molding machine to complete the feeding process. In this embodiment, the lower end of the feeding hopper 1 can be connected to the blow molding machine through a pipe.

[0020] A first linear guide rail 2 is positioned on one side of the feeding hopper 1, and a platform 21 is fixed to its output end. The first linear guide rail 2 drives the platform 21 to move vertically. Plastic particles are packaged in bags, and multiple bags of plastic particles can be stacked on the platform 21. First, the topmost bag of plastic particles is moved along the first linear guide rail 2 to align with the opening of the feeding hopper 1. Then, the topmost bag of plastic particles is pushed into the feeding hopper 1 for loading. Each time manual handling is required, multiple bags of plastic particles can be stacked on the platform 21, reducing frequent and repetitive manual handling and optimizing the loading process.

[0021] Specifically, a pusher plate 3 is provided at the top of the first linear guide rail 2. The pusher plate 3 can move towards or away from the feeding hopper 1 to push a bag of plastic particles into the feeding hopper 1. The pusher plate 3 can be driven by an electric telescopic rod, a telescopic cylinder, or other driving components.

[0022] In some embodiments, a barrier net 6 is fixed on the first linear guide rail 2. The barrier net 6 is arranged around the first linear guide rail 2 and is located in the middle of the first linear guide rail 2. Specifically, there is a space between the lower part of the barrier net 6 and the lower part of the first linear guide rail 2, which allows the staff to place the packaged plastic particles on the platform 21 through this space. When the platform 21 moves the topmost package of plastic particles to the position corresponding to the feeding hopper 1, the topmost package of plastic particles is offset from the barrier net 6. The second topmost package of plastic particles is blocked by the barrier net 6, which prevents the second package of plastic particles from moving along with the first package of plastic particles when the first package of plastic particles is pushed, thus preventing the situation of multiple stacked packages of plastic particles from tipping over.

[0023] In some embodiments, a cutting blade 4 is installed inside the feeding hopper 1. The cutting blade 4 is used to cut open the single-packaged plastic particles located in the feeding hopper 1. Specifically, when the packaged plastic particles fall into the feeding hopper 1, they will land on the cutting blade 4, which will cut open the packaging bag and allow the plastic particles to fall out, thus achieving the feeding of plastic particles.

[0024] Specifically, the two ends of the cutting blade 4 are fixed to the two symmetrical inner walls of the feeding hopper 1, and it is located in the middle of the feeding hopper 1. By fixing both ends of the cutting blade 4 to the two symmetrical inner walls of the feeding hopper 1, the length of the cutting blade 4 is ensured, allowing it to cut larger slits in the plastic particle packaging bags, thus enabling faster feeding of the plastic particles. Furthermore, because the cutting blade 4 is located in the middle of the feeding hopper 1, it aligns with the middle of the packaging bag during the descent of the packaging belt, creating an opening in the middle of the bag and making it easier for the plastic particles to fall out of the bag, facilitating feeding.

[0025] Reference Figure 2 and Figure 3 In some embodiments, a pressure plate 7 and a first telescopic member 8 are also included. The pressure plate 7 is located above the feeding hopper 1, and the first telescopic member 8 is connected to the pressure plate 7 and is used to move the pressure plate 7 toward or away from the cutting blade 4. When a packaging bag filled with plastic particles falls into the feeding hopper 1 and rests on the cutting blade 4, pressure can be applied to the packaging bag by the pressure plate 7, making it easier for the cutting blade 4 to cut the packaging bag, further facilitating feeding. The first telescopic member 8 can be an electric telescopic rod, a telescopic cylinder, or other telescopic components.

[0026] In some embodiments, a two-dimensional moving platform 9 is further included. An installation plate 91 is fixed to the output end of the two-dimensional moving platform 9. The two-dimensional moving platform 9 is used to drive the installation plate 91 to move in the vertical and horizontal directions. The first telescopic member 8 is fixedly installed on the installation plate 91. The pressure plate 7 can be moved to align with the packaging bag filled with plastic particles by means of the two-dimensional moving platform 9.

[0027] In some embodiments, a clamp 10 is also included. The clamp 10 is fixed on the mounting plate 91 and is used to clamp the packaging bag containing plastic particles. When all or most of the plastic particles in the packaging bag fall into the feeding hopper 1, the empty packaging bag can be removed from the feeding hopper 1 by the clamp 10 to make room for the next bag of plastic particles to be fed.

[0028] In some embodiments, at least one pair of clamps 10 are provided, with the pair of clamps 10 located at both ends of the cutting blade 4. That is, when most of the plastic particles from the packaging bag leak out, the two-dimensional moving platform 9 moves the pair of clamps 10 to the packaging bag position, clamps both ends of the packaging bag, and then lifts it upwards, causing the ends of the packaging strap to curl up, thereby causing the plastic particles located at both ends of the packaging bag to slide towards the middle and fall into the feeding hopper 1, further reducing the residue of plastic particles in the packaging bag. Specifically, two claws are provided at both ends of the mounting plate 91, and the four claws clamp the four corners of the packaging bag respectively. Due to the provision of four claws, the residue of plastic particles in the packaging bag is further reduced.

[0029] In some embodiments, the system further includes an insert plate 20 and a second telescopic member 30. The insert plate 20 is disposed on one side of the cutting blade 4 and can be attached to the cutting blade 4. The second telescopic member 30 is used to move the insert plate 20 towards or away from the cutting blade 4. When a packaging bag filled with plastic particles falls onto the cutting blade 4, the pressure plate 7 presses down, causing the packaging bag to move downwards, thereby inserting the insert plate 20 into the packaging bag. At this time, the second telescopic member 30 moves the insert plate 20 away from the cutting blade 4, increasing the gap at the cutting position of the packaging bag, further facilitating the falling of plastic particles into the feeding hopper 1. Specifically, the second telescopic member 30 is fixedly installed on the feeding hopper 1. The second telescopic member 30 can move the insert plate 20 by moving the guide rod 5, which can be inserted into the feeding hopper 1 and slidably connected to the feeding hopper 1. The second telescopic member 30 can be an electric telescopic rod, a telescopic cylinder, or other telescopic components.

[0030] In some embodiments, insert plates 20 are provided on both sides of the cutting blade 4. Each insert plate 20 is moved by a second telescopic member 30. That is, during the downward movement of the packaging bag, both insert plates 20 are inserted into the packaging bag, and then the two insert plates 20 move away from each other to further widen the cutting gap on the packaging bag, making it easier for plastic particles to leak out. Finally, the clamps 10 clamp the four corners of the packaging bag upward, causing the plastic particles located at both ends of the packaging bag to move towards the cutting gap, thereby reducing the residue of plastic particles in the packaging bag.

[0031] In some embodiments, the upper end of the insert plate 20 is provided in a blade shape to facilitate insertion into the packaging bag.
