Description

Technical Field

[0001] This utility model belongs to the field of waste recycling technology, specifically relating to a material recycling device for blow molding equipment. Background Technology

[0002] Blow molding is one of the core production processes for plastic products (such as plastic bottles, buckets, and industrial containers). Its steps include preform extrusion, mold closing and blow molding, cooling and demolding, and cutting. Cutting is the final step in blow molding, where cutting tools separate the finished product from preform flash, connecting rods, and other waste materials. A large amount of cutting waste is generated during blow molding, requiring recycling equipment to collect it.

[0003] Traditional blow molding equipment recycling devices often have issues with the recycling of cut materials. These materials are cut into various shapes during production, such as strips, blocks, and fragments. These irregularly shaped materials are difficult to stack tightly in the recycling device, taking up a lot of space and making subsequent packaging and transportation inconvenient. In response to this, this application proposes a material recycling device for blow molding equipment. Utility Model Content

[0004] The purpose of this invention is to provide a material recycling device for blow molding equipment in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A material recycling device for a blow molding equipment includes a recycling box, a crushing mechanism installed on the top of the recycling box, a guiding mechanism installed in the middle of the recycling box, and a compression mechanism installed at the bottom of the recycling box. The guiding mechanism includes a guide plate that is rotatably installed inside the recycling box and inclined, and a limiting rod that is fixed to the inner wall of the recycling box. One side of the limiting rod abuts against the outer wall at the top of the guide plate.

[0007] The compression mechanism includes a hydraulic cylinder fixedly installed at the bottom of the inner side of the recycling bin, and a pressure plate fixedly installed at one end of the hydraulic cylinder for compressing the cut material discharged from the guide plate. The top of the pressure plate is provided with an elastic pushing mechanism for pushing the bottom end of the guide plate to contact the inner wall of the recycling bin during compression.

[0008] As a further optimization of this utility model, the crushing mechanism includes two crushing rollers rotatably disposed on the top of the inner side of the recycling box, and a motor fixedly disposed on the outer side of the recycling box for driving the crushing rollers to rotate. A feed hopper located between the tops of the two crushing rollers is fixedly disposed on the top of the recycling box.

[0009] As a further optimization of this utility model, a bottom plate is fixedly provided on the inner bottom of the recycling bin, and the pressure plate abuts against the top of the bottom plate.

[0010] As a further optimization of this utility model, a discharge port is provided on one side of the bottom of the recycling bin, and a pressure baffle for closing the discharge port is movably provided between the inner side of the recycling bin and the bottom of the base plate.

[0011] As a further optimization of this utility model, a multi-stage electric push rod is fixedly provided at the bottom of the inner wall of the recycling bin, and the pressure-bearing baffle is fixedly connected to the top of the multi-stage electric push rod.

[0012] As a further optimization of this utility model, the elastic pushing mechanism includes a fixed sleeve plate fixedly disposed on the top of the pressure plate, a movable plate slidably disposed inside the top of the fixed sleeve plate and in cooperation with the bottom of the guide plate, and a plurality of springs fixedly disposed between the bottom of the inner side of the fixed sleeve plate and the bottom of the movable plate.

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

[0014] 1. The crushing mechanism can crush irregularly shaped cut materials. The extension and retraction of the hydraulic cylinder can drive the pressure plate to move. The moved pressure plate can compress the crushed cut materials. The compressed cut materials occupy less space, which is convenient for subsequent packaging and transportation. After the pressure plate moves, the bottom end of the guide plate can be pressed against the inner wall of the recycling box by the elastic pushing mechanism to divide the recycling box. This allows for simultaneous feeding and compression, enabling the device to continuously compress and recycle cut materials without stopping the machine, which is convenient and practical.

[0015] 2. The multi-stage electric push rod can drive the pressure baffle to rise and fall. After the pressure baffle moves down, the compression mechanism can push the compressed material out through the discharge port for discharge. After the pressure baffle moves up, it can cooperate with the compression mechanism to compress the material, which is convenient to use. The guide plate can send the material crushed by the crushing mechanism to the pressure baffle to concentrate the material and facilitate subsequent compression. Attached Figure Description

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example

[0023] like Figure 1-4 As shown, a material recycling device for a blow molding equipment includes a recycling box 1, a crushing mechanism, a guiding mechanism, and a compression mechanism. The blow molding equipment can be raised using a support frame, and the recycling box 1 is located below the cutting port of the external blow molding equipment, which can recycle the cut material.

[0024] like Figure 1-3 As shown, the crushing mechanism is installed on the top of the recycling bin 1. The crushing mechanism includes two crushing rollers 2 that are rotatably installed on the top inner side of the recycling bin 1, and a motor 21 that is fixed on the outside of the recycling bin 1 and is used to drive the crushing rollers 2 to rotate. The top of the recycling bin 1 is fixedly provided with a feeding hopper 11 located between the tops of the two crushing rollers 2. The feeding hopper 11 can be located directly below the cutting port of the external blow molding equipment, so that the cut material can enter the recycling bin 1 through the feeding hopper 11 and be recycled.

[0025] There can be two motors 21, and the output ends of the two motors 21 can be fixedly connected to one end of the two crushing rollers 2 respectively, so as to drive the two crushing rollers 2 to rotate synchronously in opposite directions. The synchronous rotation of several conventional motors is a public technology and can be accomplished by means of motion controllers and other equipment, which will not be elaborated here. After the two crushing rollers 2 rotate synchronously in opposite directions, they will crush the irregularly shaped cut material fed into the feed hopper 11 to reduce the volume of the cut material.

[0026] like Figure 2As shown, the material guiding mechanism is installed in the middle of the recycling box 1, and the compression mechanism is installed at the bottom of the recycling box 1. The material guiding mechanism includes a guide plate 3 that is rotatably installed inside the recycling box 1 and inclined, and a limiting rod 31 that is fixed to the inner wall of the recycling box 1. One side of the limiting rod 31 abuts against the outer wall of the top of the guide plate 3. The material guiding mechanism can guide the material cut by the crushing mechanism to one side of the compression mechanism. The length of the guide plate 3 is greater than the length of the recycling box 1, so that the bottom end of the guide plate 3 will abut against the inner wall of the recycling box 1 after it rotates upward. The limiting rod 31 can support the top of the guide plate 3, so that the guide plate 3 can be kept in an inclined state.

[0027] like Figure 2 As shown, a discharge port 12 is provided on one side of the bottom of the recycling box 1. A bottom plate 15 is fixedly provided on the bottom inner side of the recycling box 1. A pressure baffle 14 for closing the discharge port 12 is movably provided between the bottom inner side of the recycling box 1 and the bottom of the bottom plate 15. A multi-stage electric push rod 13 is fixedly provided on the bottom inner wall of the recycling box 1. The pressure baffle 14 is fixedly connected to the top of the multi-stage electric push rod 13. The pressure baffle 14 can be L-shaped. A conveyor belt for conveying the compressed and cut material can be provided on the outside of the discharge port 12 of the recycling box 1.

[0028] The multi-stage electric push rod 13 can extend and retract to drive the pressure baffle 14 to rise and fall. After the pressure baffle 14 moves down, it will disengage from the discharge port 12 so that the compression mechanism can push the compressed material out through the discharge port 12 for discharge. After the pressure baffle 14 moves up, it can close the discharge port 12. The upward-moving pressure baffle 14 can cooperate with the compression mechanism to compress the material, which is convenient to use. The guide plate 3 can send the material crushed by the crushing mechanism to the pressure baffle 14 to concentrate the material and facilitate subsequent compression of the material.

[0029] like Figure 2 and Figure 4 As shown, the compression mechanism includes a hydraulic cylinder 4 fixedly installed at the bottom of the inner side of the recycling box 1, and a pressure plate 41 fixedly installed at one end of the hydraulic cylinder 4 for compressing the cut material discharged from the guide plate 3. The top of the pressure plate 41 is provided with an elastic pushing mechanism for pushing the bottom end of the guide plate 3 to contact the inner wall of the recycling box 1 during compression. The pressure plate 41 is in cooperation with the top of the bottom plate 15, and the bottom plate 15 can support and limit the pressure baffle 14 and other components.

[0030] The hydraulic cylinder 4 can extend and retract to drive the pressure plate 41 to move. After moving, the pressure plate 41 can push the bottom plate 15 cutting material to the side of the pressure baffle 14, thereby compressing the crushed material. The compressed material occupies less space, which is convenient for subsequent packaging and conveying. Moreover, the multi-stage electric push rod 13 and motor 21 are existing equipment, and their specific models can be selected according to actual needs, which will not be elaborated here.

[0031] like Figure 2 and Figure 4 As shown, the elastic pushing mechanism includes a fixed sleeve plate 42 fixedly mounted on the top of the pressure plate 41, a movable plate 43 slidably mounted inside the top of the fixed sleeve plate 42 and in cooperation with the bottom of the guide plate 3, and a plurality of springs 44 fixedly mounted between the bottom of the inner side of the fixed sleeve plate 42 and the bottom of the movable plate 43. The springs 44 can connect the movable plate 43 and the fixed sleeve plate 42.

[0032] When compressing and cutting materials, the pressure plate 41 will move towards the pressure baffle 14, thereby driving the fixed sleeve plate 42 and the movable plate 43 to move together. At this time, the movable plate 43 will push the bottom end of the guide plate 3 and cause the guide plate 3 to rotate, so that the bottom end of the rotated guide plate 3 can abut against the inner wall of the recycling box 1 to separate the recycling box 1. This allows for simultaneous feeding and compression, enabling the device to continuously compress and recycle the cut materials without stopping the machine.

[0033] As the pressure plate 41 continues to move toward the pressure baffle 14, the bottom of the guide plate 3 is pressed against the inner wall of the recycling box 1, preventing the guide plate 3 from moving. At this time, the movable plate 43 will slowly retract into the fixed sleeve 42 under the tilting guidance of the guide plate 3, so as not to damage the pressure plate 41 and other components.

[0034] It should be noted that, when using this material recycling device for blow molding equipment, the feeding hopper 11 of the recycling device is first placed directly below the cutting port of the external blow molding equipment, so that the material cut by the blow molding equipment can enter the recycling box 1 through the feeding hopper 11 and be recycled.

[0035] At the same time, the motor 21 is turned on to drive the two crushing rollers 2 to rotate synchronously in opposite directions. After the two crushing rollers 2 rotate synchronously in opposite directions, they will crush the irregularly shaped cutting material fed into the feed hopper 11 to reduce the volume of the cutting material. The guide plate 3 can send the cutting material after being crushed by the crushing mechanism to the pressure baffle 14 to concentrate the cutting material and facilitate subsequent compression of the cutting material.

[0036] Then, the hydraulic cylinder 4 extends and retracts to drive the pressure plate 41 to move. After moving, the pressure plate 41 can push the bottom plate 15 cutting material towards the pressure baffle 14 side, thereby compressing the crushed material. The compressed material occupies less space, and when compressing the material, the pressure plate 41 will move towards the pressure baffle 14 side, thereby driving the fixed sleeve plate 42 and the movable plate 43 to move together. At this time, the movable plate 43 will push the bottom end of the guide plate 3 and cause the guide plate 3 to rotate, so that the bottom end of the rotated guide plate 3 can abut against the inner wall of the recycling box 1 to separate the recycling box 1. Thus, feeding and compression can be carried out at the same time, so that the feeding and compression processes of the device will not affect each other, and the device can continuously compress and recycle the material without stopping.

[0037] After compression, the multi-stage electric push rod 13 can be shortened to drive the pressure baffle 14 to move downward. After moving downward, the pressure baffle 14 will disengage from the discharge port 12 so that the compression mechanism can push the compressed material out through the discharge port 12 for discharge. After the pressure baffle 14 moves upward, it can close the discharge port 12 so that other materials can be compressed.

[0038] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
