The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application. The specific structure of the present application is shown in Figures 1-8 .

[0034] The embodiment 1 is a cooling device for injection molded bottle caps, comprising a cooling pool 1, two vertical seats 2 are respectively fixedly installed at the bottom of the cooling pool 1, the bottom of each vertical seat 2 is fixed on the top of a ground connecting seat 3, the bottom of the ground connecting seat 3 is fixed on the ground, a cooling cavity 4 is arranged in the cooling pool 1, cooling liquid 5 is stored in the cooling cavity 4, a water filtering and material guiding mechanism is installed in the cooling cavity 4, a jacking control mechanism is installed in the space below the cooling pool 1, the top of the jacking control mechanism is movably and sealingly extended into the cooling cavity 4 and fixedly connected with the bottom of the water filtering and material guiding mechanism, the inside of the cooling cavity 4 above the water filtering and material guiding mechanism is used for receiving the high-temperature injection molded bottle caps 6 falling from the upstream, and lateral protection plates 7 are symmetrically fixedly installed on the front and rear sidewalls of the cooling pool 1.

[0035] When the injection molded bottle caps 6 falling from the upstream are received, the cooling device for injection molded bottle caps 6 in the design can quickly cool and shape the high-temperature injection molded bottle caps 6 by means of the cooling liquid 5. After the shaping of the numerous bottle caps falling in succession is completed, the current injection molding work can be temporarily stopped, the water filtering and material guiding mechanism is driven by the jacking control mechanism to be jacked upward, the cooled bottle caps are jacked upward, and after being separated from the cooling cavity 4, the bottle caps are guided to the left and right sides. After the guiding is completed, the water filtering and material guiding mechanism is controlled to be driven by the jacking control mechanism to be reset, and then the injection molding equipment in the upstream is started to continue the injection molding work.

[0036] The bottle caps guided to the left and right sides will continue to be inclined downward and enter the secondary material guiding members, and then fall into the corresponding external bottle cap collecting equipment at the end of the secondary material guiding members to be collected.

[0037] In any of the above schemes, it is preferred that secondary material guiding members are respectively installed on the two sides of the cooling pool 1, the upper end of each secondary material guiding member is used for receiving the injection molded bottle caps 6 discharged from the cooling pool 1, and the lower end of each secondary material guiding member is used for being connected with an external bottle cap collecting equipment.

[0038] In any of the above schemes, it is preferred that the water filtering and material guiding mechanism comprises a ridge type filter plate 8 arranged in the cooling cavity 4, the front and rear sides of the ridge type filter plate 8 abut against the inner walls of the cooling cavity 4, the left and right ends of the ridge type filter plate 8 are formed with L-shaped angle steel segments, the vertical segments 801 of each L-shaped angle steel segment abut against the corresponding inner walls of the cooling cavity 4, the bottom of the horizontal segment 802 of each L-shaped angle steel segment is used for being fixedly connected with the top of the jacking control mechanism, and the surfaces of the inclined segments 803 on the two sides of the ridge type filter plate 8 are provided with a plurality of water filtering mesh holes 804.

[0039] The up-down movement of the water filtering and material guiding mechanism mainly relies on the up-down jacking of the jacking and position controlling mechanism, which can drive the whole ridge-shaped filter plate 8 to move up and down, and can drive the vertical segment 801 of the L-shaped angle steel segment to abut against the inner wall of the cooling cavity 4 to realize the constraint and position limiting, so as to ensure the stability during the up-down movement.

[0040] When the inclined segments 803 on the left and right sides of the ridge-shaped filter plate 8 are higher than the cooling pool 1 and the top of the vertical segment 801 of the L-shaped angle steel segment is flush with the top of the cooling pool 1, the various injection molded bottle caps 6 inside the cooling pool 1 are directly moved downward and outward to the corresponding side secondary material guiding member under the action of gravity, and then continue to fall downward, and finally fall into the inside of the corresponding end portion external collecting equipment.

[0041] During the downward material guiding of the injection molded bottle caps 6, the excess water will continuously flow downward to the inside of the cooling cavity 4 through the water filtering mesh hole 804, and the small amount of residual water will continue to be dried under the action of the subsequent first fan 17 and second fan 18.

[0042] In any of the above schemes, preferably, the jacking and position controlling mechanism comprises two synchronous jacking electric cylinders 9 which are symmetrically arranged and fixedly installed at the top of the ground connecting base 3, and the two synchronous jacking electric cylinders 9 are in synchronous lifting state in the working state, and the top of the piston rod of each synchronous jacking electric cylinder 9 is movably and sealingly extended to the inside of the cooling cavity 4 and fixedly connected with the bottom of the horizontal segment 802 of the L-shaped angle steel segment at the corresponding top.

[0043] When the jacking and position controlling mechanism works, the synchronous starting of the two synchronous jacking electric cylinders 9 on the two sides can drive the ridge-shaped filter plate 8 at the top to complete the lifting control as required, so as to realize the jacking and material guiding of the injection molded bottle caps 6.

[0044] In any of the above schemes, preferably, a drainage pipe joint 11 with a drainage valve 10 is fixedly installed at the bottom center of the cooling pool 1, and the inside of the drainage pipe joint 11 is in communication with the inside of the cooling cavity 4.

[0045] When the water inside the cooling cavity 4 becomes higher in temperature or turbid after a long time of use, the opening of the drainage valve 10 can quickly drain the water outside and wait for the injection of new cooling liquid 5 into the inside of the cooling cavity 4.

[0046] Preferably in any of the above solutions, the sub-guide member comprises a sub-guide net plate 12 arranged obliquely, an inner end of the sub-guide net plate 12 is hingedly connected to an upper lug 13 of the side wall of the cooling pool 1, an outer end of the sub-guide net plate 12 is arranged obliquely downward, and an oblique control cylinder 14 is hingedly connected to a lower end of the sub-guide net plate 12.

[0047] The sub-guide member in the utility model is mainly used for receiving the injection molded bottle cap 6 from the upstream guide, and the injection molded bottle cap 6 falls on the sub-guide net plate 12, and because the outer end of the sub-guide net plate 12 is arranged obliquely downward, the bottle cap on the sub-guide net plate 12 is continuously guided downward, and finally falls into the inside of the external collecting device.

[0048] In the process of guiding by the sub-guide net plate 12, the extension and retraction of the corresponding oblique control cylinder 14 can drive the change of the inclination angle of the sub-guide net plate 12 hingedly connected to the top, so as to quickly control the effect and speed of guiding the injection molded bottle cap 6 on the sub-guide net plate 12 downward, and avoid the occurrence of the injection molded bottle cap 6 on the sub-guide net plate 12.

[0049] Embodiment 2: Compared with embodiment 1, the difference lies in that it further comprises the following technical features:

[0050] Preferably in any of the above solutions, the bottom of each of the two lateral protection plates 7 below the sub-guide net plate 12 is inwardly and horizontally folded to form a horizontal supporting section 701, and a first fan 17 is installed on the top of each horizontal supporting section 701, and the first fan 17 is used for drying the surface moisture of the injection molded bottle cap 6 passing through the sub-guide net plate 12.

[0051] Preferably in any of the above solutions, a second fan 18 is fixedly installed on the side wall of the cooling pool 1 on the inner side of each sub-guide net plate 12, and the second fan 18 is used for drying the surface moisture of the injection molded bottle cap 6 passing through the sub-guide net plate 12.

[0052] The first fan 17 and the second fan 18 are installed in cooperation to simultaneously dry the surface moisture of the injection molded bottle cap 6 on the sub-guide net plate 12 at the current position, and the two fans cooperate with each other to better improve the drying effect and ensure that the surface moisture of the injection molded bottle cap 6 is quickly dried.

[0053] Preferably in any of the above solutions, a transition inclined plate 16 is fixedly installed on the side wall of the cooling pool 1 above each sub-guide net plate 12, and an outer end of the transition inclined plate 16 is arranged obliquely downward.

[0054] The installed transition inclined plate 16 can better ensure that the injection molded bottle cap 6 completes the receiving control of the middle part of the bottle cap during the falling process when guiding the material downward.

[0055] In any of the above solutions, it is preferred that the angle between the two inclined sections 803 of the ridge-shaped filter plate 8 is 120°-150°.

[0056] Controlling the angle between the two inclined sections 803 of the ridge-shaped filter plate 8 can ensure the smoothness of the injection molded bottle cap 6 falling on the surface of each inclined section 803 when it is set to incline downward, avoiding the problem of unsmooth bottle cap guiding caused by too slow inclination angle.

[0057] Specific working principle: When the device is working, the injection molded bottle cap 6 cooling device can quickly cool and shape the high-temperature injection molded bottle cap 6 when receiving the high-temperature injection molded bottle cap 6 falling from above by relying on the cooling liquid 5.

[0058] After the shaping of the numerous bottle caps falling one after another is completed, the current injection work can be suspended, the filter water guiding mechanism is driven upward by the jacking control mechanism to jacking the cooled bottle caps upward, and after leaving the cooling cavity 4, the bottle caps are guided to the left and right sides.

[0059] After the guiding is completed, the filter water guiding mechanism is controlled to return to the original position by the jacking control mechanism, and at this time the upstream injection equipment is started to continue the injection work. The bottle caps guided to the left and right sides will continue to incline downward into the secondary guiding part, and after being guided by the secondary guiding part, they will fall into the corresponding external bottle cap collecting equipment inside to complete the collection.

[0060] As can be seen from the above, the injection molded bottle cap 6 cooling device is mainly arranged below the outlet of the upstream bottle cap injection molding machine, and the extruded high-temperature bottle cap falls directly into the cooling cavity 4 and is quickly water-cooled under the action of the cooling liquid 5. The bottle cap directly falls into the cooling liquid 5, avoiding the impact deformation caused by the traditional falling of the bottle cap, and at the same time realizing the quick cooling and shaping; when a certain number of bottle caps are accumulated in the cooling pool 1 and are water-cooled, the jacking control mechanism is controlled to jacking and driving the filter water guiding mechanism to move upward above the liquid level of the cooling liquid 5, and at the same time, the cooled injection molded bottle cap 6 is directly jacked out of the cooling pool 1 and guided to the left and right sides under the action of the inclined sections 803 of the ridge-shaped filter plate 8, thereby realizing the quick guiding; the first fan 17 and the second fan 18 can quickly dry the injection molded bottle cap 6 during the inclined downward guiding process, effectively removing the residual moisture on the surface of the injection molded bottle cap 6.

[0061] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application; any alternative improvement or change made by those skilled in the art to the embodiments of the present application falls within the protection scope of the present application.
