Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to a bottle injection molding machine with a filtration function. Background Technology

[0002] Injection molding machines are capable of molding complex, precisely dimensional, or densely textured plastic products with metal inserts in a single process. They are widely used in national defense, machinery and electronics, automotive, transportation, building materials, packaging, agriculture, education and healthcare, and various aspects of daily life.

A water inlet is provided on the upper end of the bottle cap.

[0009] As an improved technical solution, an adjustment frame is fixedly provided at the end of the ring sleeve away from the connecting frame, an adjustment rod is inserted into the middle of the adjustment frame, an adjustment sleeve is threaded on the outer wall of the adjustment rod, and the outer wall of the end of the adjustment rod located on the inner wall of the adjustment sleeve has a thread that matches the adjustment sleeve.

[0011] As an improved technical solution, the positioning sleeve and the upper end of the long rod are rotatably connected, the sand and gravel filter plate is fixedly sleeved on the outer wall of the upper end of the long rod, and the magnetic filter plate and the activated carbon filter plate are movably sleeved on the outer wall of the long rod.

[0012] As an improved technical solution, the outer wall of the positioning sleeve is fixedly provided with two sets of symmetrical connecting plates. The lower end of the connecting plate is fixedly provided with a first spring. The lower end of the first spring is fixedly provided with a brush plate. The lower end of the brush plate is provided with brush bristles, and the brush bristles are in contact with the upper surface of the sand and gravel filter plate.

[0013] As an improved technical solution, the installation assembly includes an installation rod fixedly disposed at the lower end of the sand and gravel filter plate. An insert plate is movably inserted into the inner wall of the installation rod. Two sets of receiving blocks are provided on the outer wall of one end of the insert plate. The receiving blocks movably pass through the inner wall of the installation rod. A second spring is provided at the end of the insert plate away from the receiving blocks.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the chilled water to be filtered is injected into the filter bottle through the water inlet at the top of the bottle cap. The chilled water first passes through a sand and gravel filter plate, which can intercept larger fixed particles such as mud and welding slag in the chilled water. Then, the chilled water passes through a magnetic filter plate, which can adsorb small metal particles and metal debris in the chilled water, preventing metal particles and metal debris from entering the mold water channel and causing blockage.

[0017] 2. In this utility model, when larger fixed particles such as mud, sand, and welding slag in chilled water are intercepted and filtered through a sand and gravel filter plate, these larger impurities tend to accumulate on the upper part of the sand and gravel filter plate, causing blockage of the filter holes. The starting motor drives the adjusting component to rotate, which in turn drives the first block to rotate. The first block, through a positioning sleeve, drives the connecting plate to rotate, which in turn drives the brush plate to rotate. Under the reverse elastic force of the first spring, the bristles at the lower end of the brush plate fit more closely to the upper surface of the sand and gravel filter plate, thus cleaning the upper surface of the sand and gravel filter plate, preventing blockage, and improving the filtration efficiency of the chilled water.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0029] like Figure 1 and Figure 3 As shown in the figure, this embodiment provides a bottle injection molding machine with a filtration function, including a filter bottle 1 and a base 2 located at the four corners of the lower end of the filter bottle 1. A bottle cap 3 is provided on the upper end of the base 2, and a motor 4 is provided on the upper end of the bottle cap 3. An adjustment component 6 is provided at the lower end of the motor 4. The adjustment component 6 includes a rotating shaft 61 located at the lower end of the motor 4. A first block 62 is provided at the lower end of the rotating shaft 61. A positioning sleeve 63 is fitted on the outer wall of the first block 62. A long rod 64 is provided at the lower end of the positioning sleeve 63. A sand and gravel filter plate 10, a magnetic filter plate 11, and an activated carbon filter plate 12 are respectively fitted on the outer wall of the long rod 64 from top to bottom. Two sets of installation components 7 are provided at the lower end of the sand and gravel filter plate 10. A water outlet pipe 8 is connected to the lower end of the outer wall of the filter bottle 1. An injection molding machine 9 is provided at the water outlet end of the water outlet pipe 8.

[0030] The chilled water to be filtered is injected into the filter bottle 1 through the inlet at the top of the bottle cap 3. The chilled water first passes through the sand and gravel filter plate 10, which can intercept larger fixed particles such as mud, sand and welding slag in the chilled water. Then the chilled water passes through the magnetic filter plate 11, which can adsorb small metal particles and metal debris in the chilled water, preventing metal particles and metal debris from entering the mold water channel and causing blockage. Then the chilled water passes through the activated carbon filter plate 12, which can clean the water quality and reduce the risk of scaling in the mold water channel.

[0031] like Figure 1 and Figure 2As shown, the fixing component 5 includes a connecting ring 51 located at the lower end of the bottle cap 3. Two sets of symmetrical ring sleeves 52 are fitted on the outer wall of the connecting ring 51. A connecting frame 53 is fixedly installed on the upper end of the outer wall of the filter bottle 1. The ends of the two sets of ring sleeves 52 that are close to each other are hinged to the inner wall of the connecting frame 53. A water inlet is provided at the upper end of the bottle cap 3. An adjusting frame 54 is fixedly installed at the end of the ring sleeve 52 away from the connecting frame 53. An adjusting rod 55 is inserted into the middle of the adjusting frame 54. An adjusting sleeve 56 is threaded on the outer wall of the adjusting rod 55. The outer wall of the adjusting rod 55 located on the inner wall of the adjusting sleeve 56 has a thread that matches the adjusting sleeve 56. The end of the adjusting rod 55 away from the adjusting sleeve 56 is hinged to one of the adjusting frames 54.

[0032] When it is necessary to open the filter bottle 1 for cleaning, the adjusting sleeve 56 can be rotated to unscrew the adjusting sleeve 56 from the threaded end of the adjusting rod 55. Then, the adjusting rod 55 is rotated to keep the adjusting rod 55 parallel to the adjusting frame 54. Next, the ring 52 is unfolded to both sides along the connecting frame 53 so that the ring 52 moves out from the outer wall of the connecting ring 51. Then, the bottle cap 3 can be lifted up to complete the removal of the bottle cap 3. When it is necessary to install the bottle cap 3, the bottle cap 3 can be placed on the upper end of the filter bottle 1. The ring 52 is rotated to cover the outer wall of the connecting ring 51. The two sets of adjusting frames 54 are parallel to each other. Then, the adjusting rod 55 is rotated to make the adjusting rod 55 perpendicular to the adjusting frame 54. Then, the adjusting sleeve 56 is rotated to make the front end of the adjusting sleeve 56 fit against the outer wall of the adjusting frame 54. At this time, the ring 52 cannot be rotated, and the bottle cap 3 cannot be lifted up, thus completing the fixation of the bottle cap 3.

[0033] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the upper end of the positioning sleeve 63 has a first square groove that mates with the first square block 62. The first square block 62 is movably inserted into the first square groove. The lower end of the inner wall of the filter bottle 1 is fixedly provided with a receiving bracket 66. The upper end of the receiving bracket 66 is fixedly provided with a second square block 65. The lower end of the long rod 64 has a second square groove that mates with the second square block 65. The second square block 65 is movably inserted into the second square groove. The upper ends of the positioning sleeve 63 and the long rod 64 are rotatably connected. The sand and gravel filter plate 10 is fixedly sleeved on the outer wall of the upper end of the long rod 64. The magnetic filter plate 11 and the activated carbon filter plate 12 are movably sleeved on the outer wall of the long rod 64. The outer wall of the positioning sleeve 63 is fixedly provided with two sets of symmetrical connecting plates 67. The lower end of the connecting plate 67 is fixedly provided with a first spring 68. The lower end of the first spring 68 is fixedly provided with a brush plate 69. The lower end of plate 69 is provided with bristles, which are in contact with the upper surface of sand and gravel filter plate 10. The mounting assembly 7 includes a mounting rod 71 fixedly mounted on the lower end of sand and gravel filter plate 10. An insert plate 72 is movably inserted into the inner wall of the mounting rod 71. Two sets of receiving blocks 73 are provided on the outer wall of one end of the insert plate 72. The receiving blocks 73 movably pass through the inner wall of the mounting rod 71. A second spring 74 is provided at the end of the insert plate 72 away from the receiving blocks 73. The end of the second spring 74 away from the insert plate 72 is fixedly connected to the inner wall of the mounting rod 71. A limiting block 75 is fixedly provided at the upper end of the inner wall of the mounting rod 71. The upper end of the insert plate 72 is movably sleeved on the outer wall of the limiting block 75. The magnetic filter plate 11 and the activated carbon filter plate 12 are movably sleeved on the outer wall of the mounting rod 71 at both ends. The lower ends of the magnetic filter plate 11 and the activated carbon filter plate 12 overlap the receiving blocks 73.

[0034] When the sand and gravel filter plate 10 intercepts and filters larger fixed particles such as mud, sand, and welding slag in the chilled water, these larger impurities tend to accumulate on the upper part of the sand and gravel filter plate 10, causing blockage of the filter holes. The starting motor 4 drives the adjusting component 6 to rotate, which in turn drives the first block 62 to rotate. The first block 62 drives the connecting plate 67 to rotate through the positioning sleeve 63, and the connecting plate 67 drives the brush plate 69 to rotate. Under the reverse elastic force of the first spring 68, the bristles at the lower end of the brush plate 69 fit more closely to the upper surface of the sand and gravel filter plate 10, so that the brush plate 69 can clean the upper surface of the sand and gravel filter plate 10, preventing blockage and improving the filtration efficiency of the chilled water.

[0035] When the bottle cap 3 leaves the upper end of the filter bottle 1, the first block 62 is pulled out from the first square groove at the upper end of the positioning sleeve 63. Then, the operator lifts the positioning sleeve 63, causing the second square groove at the lower end of the long rod 64 to move out from the upper end of the second block 65. At this time, the sand filter plate 10, the magnetic filter plate 11, and the activated carbon filter plate 12 move out of the outer wall of the filter bottle 1 along with the long rod 64. Then, the sliding plate 72 compresses the second spring 74, causing the receiving block 73 to move towards the inner wall of the mounting rod 71, so that the receiving block 73 leaves the lower end of the magnetic filter plate 11 and the activated carbon filter plate 12. Then, the magnetic filter plate 11 and the activated carbon filter plate 12 slide down along the mounting rod 71 and the long rod 64, thus completing the sand filter plate 10 and the magnetic filter plate 12. The separation of filter plate 11 and activated carbon filter plate 12 facilitates the individual cleaning of multiple filter plates, making them easier to maintain and preventing excessive impurities from accumulating on the filter plates and affecting their filtration effect. The second block 65 facilitates the positioning of the long rod 64 during installation. After cleaning the filter plates, the magnetic filter plate 11 and activated carbon filter plate 12 are sequentially placed onto the upper end of the mounting rod 71 and the long rod 64. Then, the insert plate 72 is released, and under the reverse elastic force of the second spring 74, the receiving block 73 passes through the mounting rod 71, so that the magnetic filter plate 11 and activated carbon filter plate 12 overlap the upper end of the receiving block 73 to complete the installation of the magnetic filter plate (11) and activated carbon filter plate (12).

[0036] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
