Description

Technical Field

[0001] The utility model relates to the technical field of hot water shrinking machines, in particular to a water curtain type hot water shrinking machine. Background Art

[0002] Traditional hot water shrinking machines generally shrink the packages by bringing the packages into contact with the hot water in the water tank. The main working process is: By utilizing a lifting mechanism to adjust the height of the conveyor line or table for placing the packages, the packages on the conveyor line or table can be immersed in the hot water in the water tank or float out of the hot water.

[0003] This method has the following defects or deficiencies: when the package is shrinking, the lifting mechanism needs a certain amount of time to adjust the height of the conveyor line or the placement table, so when the conveyor line moves the package to this link, it has to pause for a certain period of time: the package first moves downward to contact the hot water, and after shrinking, it must float up out of the hot water to return to the original conveying path. In summary, it can be seen that the traditional hot water shrinking machine cannot shrink the package while conveying the package uninterruptedly, so the production efficiency is relatively low.

DETAILED DESCRIPTION

[0031] The following will be combined with the attached embodiment of the utility model Figure 1-9 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example:

[0033] like Figures 1 to 9 As shown, the utility model discloses a water curtain type hot water shrinking machine, including a frame 1, in which a packaging material conveying frame 11 with a forward and backward conveying direction and a water pump circulation system are arranged, wherein the water pump circulation system includes a first water injection mechanism, a second water injection mechanism, a hot water concentration mechanism and a water supply mechanism. In this structure, the first water injection mechanism and the second water injection mechanism are respectively used to supply water to the upper and lower ends of the packaging material conveying frame 11, the hot water concentration mechanism is used to receive water below the packaging material conveying frame 11, and the water supply mechanism is used to enable the hot water concentration mechanism to supply water to the first water injection mechanism and the second water injection mechanism.

[0034] The working principle of this structure is as follows: in the process of the packaging conveying rack 11 conveying the packaging, the packaging will pass through the drainage route of the first water injection mechanism and the second water injection mechanism. The first water injection mechanism and the second water injection mechanism are respectively used to pour hot water on the surface of the packaging from the upper and lower sides of the packaging to achieve the effect of shrinking the packaging. At the same time, when the hot water hits the packaging, it will naturally fall down. At this time, the hot water concentration mechanism is used to receive and collect the hot water, and wait for the water supply mechanism to re-supply the hot water to the first water injection mechanism and the second water injection mechanism. During this process, the conveying process of the packaging conveying rack 11 can continue without interruption.

[0035] The first water injection mechanism includes a water bucket 2 fixedly arranged above the packaging material conveying rack 11, and a strip-shaped water outlet slot 211 is provided at the lower end of the water bucket 2, and the extension direction of the water outlet slot 211 is from left to right. At the same time, the second water injection mechanism includes a water inlet square pipe 3, which is arranged below the packaging material conveying rack 11, and a strip-shaped water spray slot 31 is provided on the upper end surface of the water inlet square pipe 3, and the extension direction of the water spray slot 31 is from left to right. Through this structure, the water bucket 2 and the water inlet square pipe 3 can respectively pour hot water on the packaging from the upper and lower sides of the packaging.

[0036] The hot water concentration mechanism includes a water tank 4, which is arranged at the lower end of the water inlet square pipe 3, and the upper end of the water tank 4 is opened; the frame 1 is provided with two first water baffles 51 between the water inlet square pipe 3 and the water tank 4, the edges of the first water baffles 51 are fixedly connected to the inner side wall of the frame 1 and a water droplet 53 is reserved between the ends of the two first water baffles 51 close to each other, and the water droplet 53 is located above the opening at the upper end of the water tank 4. At the same time, the first water baffle 51 has a first water guide slope 52; the frame 1 is provided with second water baffles 54 on the left and right sides of the packaging conveying rack 11, the second water baffle 54 is fixedly arranged in the frame 1 and its upper end is higher than the packaging conveying rack 11, and the upper end of the second water baffle 54 is provided with a second water guide slope 55.

[0037] The working principle of this structure is as follows: after the water bucket 2 and the water inlet square pipe 3 drain water outwards, the hot water will flow onto the first water baffle 51. At this time, the hot water must flow downwards through the drain port 53, so the hot water discharged from the water bucket 2 and the water inlet square pipe 3 can be collected by the water tank 4. Since the water bucket 2 is located at a higher position, water splashes will occur when the hot water is poured onto the packaging or the first water baffle 51. In this structure, the second water baffle 54 and the second water guide slope 55 on the second water baffle 54 can further play a role in blocking water, so that the splashed hot water can flow downwards along the side wall of the second water baffle 54 to the first water baffle 51 or the drain port 53. The first water guide slope 52 can be used to divert the hot water so that the hot water can flow toward the drain port 53.

[0038] The water supply mechanism includes a centrifugal pump 41 and a diverter box 42. The diverter box 42 is fixedly arranged on the water tank 4 and is connected to the water inlet square pipe 3 and the water bucket 2. The centrifugal pump 41 connects the diverter box 42 and the water tank 4 and is used to supply water to the diverter box 42.

[0039] The scoop 2 includes an outer scoop 21 and an inner scoop 22 fixedly arranged inside the outer scoop 21, and a scoop water inlet pipe 24 is arranged on the scoop 2. In this structure, the scoop water inlet pipe 24 is connected to the diversion box 42 and passes through the outer scoop 21 to communicate with the inner scoop 22. A strip-shaped water outlet 221 is arranged at the lower end of the inner scoop 22, and the water outlet 221 is connected to the outer scoop 21. In this structure, the water outlet 221 is arranged above the water outlet slot 211 and the length of the water outlet 221 is shorter than the length of the water outlet slot 211. At the same time, a plurality of water outlets 221 are arranged at intervals in the left and right directions. At the same time, a third water baffle 222 is fixedly arranged above the inner scoop 22. The third water baffle 222 is arranged horizontally and lower than the upper end of the outer scoop 21. A return water port 212 is opened on the side wall of the outer scoop 21.

[0040] The working principle of this structure is as follows: the diversion box 42 transports the hot water in the water tank 4 to the inner water bucket 22 through the water bucket inlet pipe 24. A plurality of water outlets 221 are provided at the lower end of the inner water bucket 22, which can be used to evenly flow the hot water downward from the long water outlet groove 211. At the same time, in order to prevent excessive hot water from being discharged into the inner water bucket 22, resulting in the hot water not being poured onto the packaging according to the predetermined displacement, the third water baffle 222 is used to make the hot water overflowing from the inner water bucket 22 flow into the outer water bucket 21. The return water port 212 on the side wall of the second outer water bucket 21 can be used to connect an external return water pipe. The return water pipe can be connected to the water tank 4 or connected to an external water storage tank 4, so as to discharge the hot water overflowing from the return water port 212 out of the outer water bucket 21.

[0041] The interior of the inner water bucket 22 and the interior of the outer water bucket 21 are arranged from front to back to form a plurality of V-shaped water accumulation grooves 23, wherein the long water outlet groove 211 and the water outlet 221 are respectively opened at the bottom of the V-shaped water accumulation groove 23. At the same time, the water inlet square pipe 3 is provided with a plurality of water spray grooves 31 arranged from front to back. The advantage of this structure is that the water bucket 2 and the water inlet square pipe 3 can pour hot water to the same position on the surface of the packaging multiple times, thereby lengthening the contact time between the packaging and the hot water, which is beneficial to improving the shrinkage quality.

[0042] A pull-out filter screen 43 is slidably provided at the top opening of the water tank 4. The pull-out filter screen 43 is mainly used to prevent impurities and residues from falling into the water tank 4, thereby avoiding blockage during the transportation of hot water.

[0043] In addition, in order to prevent insufficient hot water, a three-stage float 44 is provided in the water tank 4. At the same time, the water tank 4 is also connected to a water tank inlet pipe 45. The three-stage float 44 is used to detect the remaining hot water inside the water tank 4. When the hot water is too little, the water tank inlet pipe 45 can add water to the water tank 4. A heating pipe 46 is also provided in the water tank 4. When the hot water temperature is insufficient, the heating pipe 46 is used to heat the water in the water tank 4.

[0044] The scheme of injecting water into the water tank inlet pipe 45 according to the detection result of the three-stage float 44 can be completed by the existing technology. At the same time, the connection scheme between the water inlet square pipe 3, the water bucket 2 and the water tank 4, the filter net for filtering impurities and sundries in this embodiment have a lot of technical knowledge as a basis in the existing technology, so this article will not elaborate on them.
