DETAILED DESCRIPTION

[0026] In order to clearly understand the technical solution of the present application, a fully automatic intelligent freezing drum and a chloroprene rubber freezing and condensation device provided by the present application will be described in detail below in combination with specific embodiments and drawings.

[0027] The terms used in the following embodiments are only for the purpose of describing specific embodiments, and are not intended to be used as limitations to the present application. As used in the specification and claims of the present application, the singular expressions "one", "a kind of", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear indication to the contrary in the context. It should also be understood that in the following embodiments of the present application, "at least one", "one or more" refer to one, two or more than two.

[0028] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0029] Example 1, this example provides a fully automatic intelligent freezing drum, reference Figure 1 , which shows a schematic diagram of the three-dimensional structure of the fully automatic intelligent freezing drum. It can be seen from the figure that the fully automatic intelligent freezing drum includes a latex storage tank 1, a freezing drum 2 is arranged in the latex storage tank 1, and a freezing brine inlet 3 and a freezing brine outlet 4 are formed at the left and right ends of the freezing drum 2 respectively; the freezing brine inlet 3 and the freezing brine outlet 4 are rotatably connected to support ring bodies 5 respectively, and the rod part of the support ring body 5 is fixedly connected to the adjacent edge of the latex storage tank 1; a scraper 6 is arranged on one side of the outer surface of the freezing drum 2, and the blade part of the scraper 6 is opposite to the outer surface of the freezing drum 2 and forms a gap, and the blade part of the scraper 6 is used to scrape off the crystallized latex on the freezing drum 2; in order to ensure that the latex crystallized on the freezing drum 2 is removed The scraped latex lands smoothly on the washing belt on one side of the scraper blade 6 (the washing belt directly uses the existing technology on the market, which will not be described here). The blade of the scraper blade 6 is sloped, and the bottom of the slope of the scraper blade 6 faces the washing belt. The unloading part of the scraper blade 6 is used to face the upper surface of the washing belt. On the other hand, when the latex on the surface of the freezing drum 2 is crystallized, the gap between the scraper blade 6 and the outer surface of the drum is different due to the excessive cooling and icing of the outer surface of the drum or the unevenness and uneven thickness of the film. In order to adjust the gap between the scraper blade 6 and the outer surface of the drum to a suitable distance range in time, the present invention can design a distance adjustment device. The present invention cites a distance adjustment device as follows. Of course, the distance adjustment device is not limited to this embodiment. In practical applications, distance adjustment devices of other embodiments can also be used.

[0030] Continue to refer Figure 1 The distance adjustment device includes an electric telescopic cylinder 7, which is fixedly connected to one side of the latex storage tank 1 through a carrier plate 8. The telescopic movement of the electric telescopic cylinder 7 forms a fixed connection with the unloading portion of the scraper blade 6, and a pressure sensor is embedded in the blade portion of the scraper blade 6 (the pressure sensor is not shown in the figure). When the distance adjustment device is in use, once the blade portion of the scraper blade 6 contacts the raised or recessed crystal latex, the pressure on the pressure sensor will fluctuate accordingly; once the pressure value is not within the set value, the pressure sensor will transmit a signal to the terminal controller (directly using the existing technology, no further description here), and the terminal controller will immediately send an extension or retraction command to the electric telescopic cylinder 7 until the pressure on the pressure sensor returns to a suitable range.

[0031] When the freezing drum 2 is used to crystallize the latex in the latex storage tank 1, the freezing drum 2 needs to first be cooled by using frozen brine, and then the driving device is used to rotate the freezing drum 2. Finally, the rotating freezing drum 2 causes the latex to continuously crystallize along the drum surface and condense and adhere to form a film. To this end, the present invention needs to design a frozen brine cooling device for refrigerating the freezing drum 2, and the specific structure of the frozen brine cooling device is as follows.

[0032] As a first embodiment of the refrigerated brine cooling device, refer to Figure 2 , the schematic diagram of the installation structure of the frozen brine cooling device of the first embodiment is shown. It can be seen from the figure that the frozen brine cooling device includes a spray pipe 9, which can movably pass through the frozen brine inlet 3 and is placed in the inner cavity of the freezing drum 2. The spray pipe 9 is placed on the outer side of the freezing drum 2 and is fixedly connected to a reinforcing rib 10 at one end, and the reinforcing rib 10 is fixedly connected to the latex storage tank 1; the spray pipe 9 placed in the inner cavity of the freezing drum 2 is provided with a plurality of nozzles, and the spray pipe 9 is connected to a guide pipe 11, and the other end of the guide pipe 11 is connected to a first pump body, and the first pump body is placed in a storage tank filled with frozen brine (the first pump body and the storage tank are not shown in the figure). When this embodiment is used, the frozen brine in the storage tank is first pumped to the guide pipe 11 and the spray pipe 9 in sequence by the first pump body, and then the frozen brine in the spray pipe 9 is sprayed from each nozzle and evenly sprayed to the outer surface of the frozen brine, so that the outer surface of the freezing drum 2 achieves the effect of freezing and cooling.

[0033] Among them, for the fully automatic intelligent freezing drum after the frozen brine cooling device of the first embodiment, the present invention correspondingly designs a first driving device for driving the freezing drum 2 to rotate, referring to Figure 3, which is a schematic diagram of the three-dimensional structure of the first driving device. It can be seen from the figure that the first driving device includes a steering gear 32, which is fixedly connected to the latex storage tank 1, and the output shaft of the steering gear 32 forms a transmission connection with the outer wall of the frozen brine inlet 3 or the frozen brine outlet 4 of the freezing drum 2 through a conveyor belt.

[0034] As a second embodiment of the refrigerated brine cooling device, refer to Figure 4-5 ,in, Figure 4 FIG. 1 shows a schematic diagram of the installation structure of the second embodiment of the frozen brine cooling device from a first viewing angle. Figure 5 Shown is a schematic diagram of the cross-sectional structure of the second embodiment of the chilled brine cooling device from the second viewing angle. It can be seen from the above two figures that the chilled brine cooling device includes a circulating refrigeration network 12, and the circulating refrigeration network 12 is placed in the inner cavity of the freezing drum 2; the inlet pipe 17 of the circulating refrigeration network 12 is rotatably connected to the chilled brine inlet 3, and the outlet pipe 18 of the circulating refrigeration network 12 is rotatably connected to the chilled brine outlet 4; the outer wall of the inlet pipe 17 of the circulating refrigeration network 12 is transmission-connected to the rotating shaft 14 through the first belt 13, and the rotating shaft 14 is rotatably connected to the flange on the edge of the latex storage tank 1; the rotating shaft 14 is transmission-connected to the second belt 15, and the second belt 15 is transmission-connected to the output shaft of the electric motor 16, and the electric motor 16 is fixedly connected to the base 22 of the latex storage tank 1. Specifically, further in combination with Figure 6 The schematic diagram of the three-dimensional structure of the circulating refrigeration network 12 shown in the figure shows that the circulating refrigeration network 12 is composed of multiple circulating pipes, for example, the number of circulating pipes can be eight; the multiple circulating pipes are arranged in a circular array, the left ends of the multiple circulating pipes are connected to the inlet pipe 17, and the right ends of the multiple circulating pipes are connected to the outlet pipe 18. The outlet pipe 18 is rotatably connected to one end of the curved pipe 19, and the curved pipe 19 is fixedly connected to the latex storage tank 1 through a locking plate. The free end of the curved pipe 19 is used to be connected to the frozen brine temporary storage tank. The frozen brine temporary storage tank is equipped with a refrigeration device for refrigerating the brine. The refrigeration device can use the existing technology. The frozen brine temporary storage tank and the refrigeration device are not shown in the figure. The inlet pipe 17 of the circulating refrigeration network 12 is rotatably connected to the liquid inlet pipe 30 of the frozen brine filling unit; the specific structure of the frozen brine filling unit is as follows.

[0035] Continue as Figure 4As shown in the figure, the frozen brine filling unit includes a cylinder 20, which is rotatably connected to a support ring 21, and the other end of the support ring 21 is fixedly connected to the edge of the latex storage tank 1 through a base 22; a filling port for adding frozen brine is provided on the cylinder 20, and the frozen brine added to the cylinder 20 through the filling port at a regular interval comes from the frozen brine temporary storage tank, thereby realizing the recycling of the frozen brine; a second water pump body is provided in the cylinder 20 for extracting the frozen brine from the cylinder 20 into the liquid inlet pipe 30 and the inlet pipe 17, and the second water pump body is not shown in the figure.

[0036] Among them, for the fully automatic intelligent freezing drum after the frozen brine cooling device of the second embodiment, the present invention correspondingly designs a second driving device for driving the freezing drum 2 to rotate, referring to Figure 7 , which is a schematic diagram of the three-dimensional structure of the second driving structure. It can be seen from the figure that the second driving structure includes a sleeve 23, which is fixedly sleeved on the outer wall of the inlet pipe 17, and a pawl 25 is connected to the outer wall groove of the sleeve 23 through an elastic component 24 (such as a torsion spring, etc.); when the elastic component 24 is in a natural state, the back of the pawl 25 forms a conflict with the adjacent side of the outer wall groove; a circle of thorn grooves 26 are formed on the inner wall of the frozen brine inlet 3, and the thorn grooves 26 are meshed with the pawl 25 to form a ratchet mechanism.

[0037] The working principle of the fully automatic intelligent freezing drum after the second application embodiment of the frozen brine cooling device and the second driving structure is as follows: first, before using the frozen brine cooling device, the frozen brine in the frozen brine temporary storage tank needs to be injected into the cylinder 20; the second pumping pump body is started, and the second pumping pump body draws the frozen brine from the cylinder 20 into the inlet pipe 17; at the same time, the electric motor 16 is started, such as Figure 7 and Figure 4 As shown in the figure, the electric motor 16 drives the inlet pipe 17 and the circulating refrigeration network 12 to rotate along the direction a1. At this time, according to the principle of the ratchet mechanism (the prior art, which will not be repeated here), the pawl 25 will slide through the thorn groove 26 and flip toward the outer wall groove (the elastic component 24 is in a compressed state at this time), and the friction force generated between the pawl 25 and the thorn groove 26 is not enough to drive the freezing drum 2 to rotate; before the freezing drum 2 crystallizes the latex in a rotating manner, due to the continuous injection of frozen brine into the circulating refrigeration network 12, the circulating refrigeration network 12 continues to pre-refrigerate various parts of the freezing drum 2 during rotation; the frozen brine discharged from the circulating refrigeration network 12 enters the frozen brine temporary storage tank for subsequent use of the cylinder 20.

[0038] Then, when the freezing drum 2 is precooled, the rotation direction of the output shaft of the electric motor 16 is adjusted, so that the inlet pipe 17 and the circulating refrigeration pipe network 12 rotate along the direction a2, and the ratchet 25 presses the thorn groove 26 to rotate along the direction a2, which indirectly rotates the freezing drum 2 along the direction a2, and the latex is continuously crystallized along the drum surface and condensed and adhered into a film when the freezing drum 2 rotates. The present invention realizes mutual linkage among the freezing brine cooling device, the second driving structure, and the freezing drum 2 by combining the second embodiment of the freezing drum 2 and the second driving structure; when the freezing drum 2 is precooled itself, the second driving structure rotates to one side and only drives the freezing brine cooling device to rotate; and when the freezing drum 2 crystallizes the latex, the second driving structure rotates to the other side, and drives the freezing drum 2 and the freezing brine cooling device to rotate at the same time.

[0039] Compared with the prior art, the present invention can ensure that the latex on the freezing drum 2 is scraped off by the scraper blade 6 by providing a scraper blade 6, and can ensure that the latex lands smoothly on the washing belt; on the other hand, the present invention further provides a distance adjustment device to ensure that the gap between the freezing drum 2 and the scraper blade 6 is within a reasonable range.

[0040] Embodiment 2. This embodiment provides a chloroprene rubber freezing and condensation device, including the fully automatic intelligent freezing drum disclosed in the above embodiment 1, a washing belt is provided on one side of the fully automatic intelligent freezing drum (the existing technology can be used), and a cleaning machine is provided on one side of the washing belt (for example, the existing product model DLXG can be used).

[0041] Due to the presence of salt, the frozen brine may precipitate at the bottom of the water when it is in a static state; for this reason, the frozen brine in the cylinder 20 needs to be shaken and mixed to a certain extent before entering the circulating refrigeration network 12; in response to the above-mentioned problems, the present invention optimizes the frozen brine filling unit as follows.

[0042] refer to Figure 8 , which shows a schematic diagram of the optimized three-dimensional structure of the frozen brine filling unit. It can be seen from the figure that the frozen brine filling unit also includes a transmission gear 27, and the transmission gear 27 is concentrically fixedly connected to the rotating shaft 14; the peripheral edge of the cylinder 20 is formed with a circle of teeth 28 in a ring array, and the transmission teeth mesh with the circle of teeth 28 to form a linkage. When in use, when the electric motor 16 indirectly drives the circulating refrigeration pipe network 12 to rotate, the corresponding linkage transmission gear 27 and the cylinder 20 rotate (the cylinder 20 rotates on the liquid inlet pipe 30), thereby initially shaking and mixing the frozen brine in the cylinder 20.

[0043] In order to further enhance the mixing effect of the frozen brine in the cylinder 20, refer to Fig. 9, which shows a schematic diagram of the cross-section structure of the frozen brine filling unit after further optimization. It can be seen from the figure that the frozen brine filling unit also includes a driven gear ring 29, which is fixedly connected to the liquid inlet pipe 30 in a concentric manner, and a plurality of stirring blades 31 are fixedly connected to the liquid inlet pipe 30 placed on the inner side of the cylinder 20. When in use, the rotating transmission gear 27 can synchronously mesh with the driven magnetic ring to achieve rotation, so that the liquid inlet pipe 30 and the stirring blade 31 rotate; at this time, the rotation direction of the cylinder 20 and the stirring blade 31 is opposite, which forms a turbulent effect on the frozen brine in the cylinder 20 to the greatest extent, and further improves the mixing effect of the frozen brine.

A circle of thorn grooves (26) is formed on the inner wall of the frozen brine inlet (3). The thorn grooves (26) mesh with the ratchet (25) to form a ratchet mechanism.
