Description

Technical Field

[0001] The present invention relates to the technical field of glove processing equipment, and in particular to a PVC glove raw material cooling device. Background Art

[0002] PVC gloves are a type of plastic gloves, which are usually used in the fields of medical treatment, food processing and cleaning. They are made of polyvinyl chloride as raw material, mixed with other additives and other materials into an emulsion, which is then adhered to the hand mold on the assembly line after filtering, vacuuming, and standing, and then put into the oven for curing and forming, and then naturally cooled and rolled.

[0003] In the processing production line of PVC gloves, cooling equipment is mostly added to assist the cooling of PVC gloves in order to improve production efficiency. The existing glove raw material cooling devices mostly use cold air machines or equipment with refrigeration effects to cool the gloves. In order to avoid the loss of cold air, a frame that can accommodate gloves and support the movement of hand models of gloves is also provided outside the equipment.

[0004] However, since the air outlet of the refrigeration equipment is limited and the density of cold air is greater than that of warm air, it is easy to sink inside the frame. Therefore, the temperature inside the frame that can accommodate the gloves for cooling is prone to unevenness, which can easily affect the quality of the cooling operation. At the same time, since the finger joints of the gloves are relatively narrow and the gloves are mostly in a static state during the cooling process, it is easy to cause a cooling dead angle in the finger joints of the gloves, resulting in a slower cooling speed in this area, affecting the quality of the glove cooling operation. Therefore, the present application provides a PVC glove raw material cooling device to meet the needs. Summary of the invention

[0005] In view of the above problems, the present application provides a PVC glove raw material cooling device.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: a PVC glove raw material cooling device, comprising two groups of cooling pipelines distributed from top to bottom and a refrigerator arranged on the cooling pipelines, wherein a frame is provided on the refrigerator, and the two groups of cooling pipelines are both located on the inner side of the frame.

[0007] Each group of cooling pipelines includes two symmetrically distributed positioning pipes and a connecting pipe group that connects the two positioning pipes. The connecting pipe group is distributed vertically to the positioning pipes. A driving shaft is provided on the connecting pipe group. A plurality of equally distributed impellers are provided on the driving shaft. The impellers extend to the center position of the gap between the connecting pipe groups.

[0008] A movable guide conveyor belt is provided above the positioning pipe, and two groups of symmetrically distributed electric rollers are provided in the gap of the connecting pipe group. When the guide conveyor belt moves away from the positioning pipe, the electric roller can move to the position of the guide conveyor belt to receive a hand mold with a glove.

[0009] Furthermore, a linkage frame is provided on the side of the guide conveyor belt away from the positioning pipe, a support frame corresponding to the linkage frame is provided in the frame, and a driving cylinder which can control the linkage frame and the guide conveyor belt to move synchronously is provided on the support frame. When the guide conveyor belt moves away from the positioning pipe, it moves away from the hand model in a horizontal state.

[0010] Furthermore, the electric roller is provided with a positioning plate perpendicular to it, and multiple positioning plates are arranged on the same extension frame. The extension frame has a multi-section raised structure, and the raised structures are all located in the gap of the connecting pipe group. When the electric roller and the extension frame move to the original position of the guide conveyor belt, the electric roller receives the hand model in a horizontal state.

[0011] Furthermore, both ends of the extension frame are provided with alignment sleeves that can move synchronously therewith, and the alignment sleeves are provided with follower brackets that can move synchronously therewith. A second support frame corresponding to the alignment sleeve is provided in the frame, and the follower bracket runs through the second support frame. The second support frame is provided with a driving cylinder two that can control the synchronous movement of the extension frame, the alignment sleeve and the follower bracket.

[0012] Furthermore, the legs of the extension frame are all passed through the alignment sleeve and the follower bracket, and a driving motor for controlling the rotation of the extension frame, the positioning plate and the electric roller is installed on one of the sides of the two follower brackets facing the two legs of the extension frame.

[0013] Furthermore, one of the positioning pipes in the two groups of cooling pipelines is connected by a guide pipe, and the positioning pipe in the cooling pipeline distributed downwardly that is not connected to the guide pipe is provided with a liquid outlet pipe extending to the outside of the frame, and the bottom end of the liquid outlet pipe is connected to a collection rack.

[0014] The collecting rack is provided with a conveying pipe, the conveying pipe extends to the inner side of the rack, and an electric-controlled pump is provided on the conveying pipe. The positioning pipe in the cooling pipeline distributed upward and not connected with the guide pipe is connected to the conveying pipe.

[0015] Furthermore, the two driving shafts distributed from top to bottom are both arranged on the frame, and a driven wheel is provided at one end of the driving shaft, and the driven wheel is connected to the driving wheel through a linkage belt. The two driving wheels are distributed from front to back, and the two driving wheels are both arranged on the same rotating shaft, and the rotating shaft is arranged outside the frame. A power motor that can control the rotating shaft and the driving wheel to rotate synchronously is provided outside the frame.

[0016] In summary, the technical effects and advantages of the present invention are as follows:

[0017] 1. The present invention uses a refrigerator to inject cold air into the rack, forming a cooling environment with a temperature lower than low temperature inside the rack, so that the raw materials on the gloves put on the hand mold entering the rack can be quickly cooled. The two sets of cooling pipelines from top to bottom can accommodate the upper and lower four sets of hand molds entering the rack, which improves the cooling efficiency. Both sets of cooling pipelines are close to the hand molds and can be located near the hand molds to maintain the low temperature state of the air near them. It can also make the temperature of each position inside the rack tend to be consistent, so that the two sets of cooling pipelines and the four sets of hand mold channels can maintain a uniform low temperature state.

[0018] 2. The present invention is provided with a guide conveyor belt and an electric roller with switchable positions. The electric roller receives the hand mold with the glove and drives the hand mold to rotate, so that both sides of the hand mold can be cooled quickly and evenly, thereby improving the efficiency of the cooling operation. Combined with the airflow generated by the rotation of the impeller, the raw materials at the finger joints of the glove can be cooled quickly, effectively avoiding the phenomenon of incomplete cooling caused by the narrow finger joints that are prone to cooling dead corners, thereby further improving the quality of the cooling operation.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1:

[0032] refer to Figure 1-9 The PVC glove raw material cooling device shown in the figure comprises two groups of cooling pipelines distributed from top to bottom and a refrigerator 4 arranged on the cooling pipelines, a frame 3 is arranged on the refrigerator 4, and the two groups of cooling pipelines are located inside the frame 3. The air outlet of the refrigerator 4 faces the inside of the frame 3, so that the cold air used for cooling the PVC gloves can be injected into the inside of the frame 3, forming a cooling environment with a temperature lower than the low temperature inside the frame 3, so that the raw materials of the gloves put on the hand mold entering the inside of the frame 3 can be quickly cooled.

[0033] Each set of cooling pipelines includes two symmetrically distributed positioning pipelines 1 and a connecting pipe group 2 that connects the two positioning pipelines 1, and the connecting pipe group 2 is vertically distributed with the positioning pipeline 1. The arrangement of two sets of cooling pipelines from top to bottom can accommodate the upper and lower four sets of hand models to enter the interior of the rack 3, thereby improving the cooling efficiency. Both the upper and lower sets of cooling pipelines are close to the hand model, and therefore, on the inner side of the rack 3, they can be located near the hand model to maintain the low temperature of the air near it.

[0034] During the cooling process of the glove raw materials, since the refrigerator 4 is arranged at the top and two groups of cooling pipes are arranged, in order to maintain the uniformity of the temperature inside the frame 3, a driving shaft 5 is arranged on the connecting pipe group 2, and a plurality of groups of equally spaced impellers 6 are arranged on the driving shaft 5, and the impellers 6 extend to the center of the gap between the connecting pipe group 2. During the cooling process of the glove raw materials, the driving shaft 5 can drive the impeller 6 located inside the connecting pipe group 2 to rotate, thereby allowing the cold air inside the frame 3 to circulate quickly, so that the temperature of each position inside the frame 3 tends to be consistent. The phenomenon of cold air accumulating in the lower part of the inner side of the frame 3 is effectively avoided, so that the two groups of cooling pipes and the four groups of hand mold channels can maintain a uniform low temperature state, thereby improving the efficiency and quality of the cooling of the glove raw materials.

[0035] In order to make the two driving shafts 5 and the impeller 6 rotate synchronously, the two driving shafts 5 distributed from top to bottom are both arranged on the frame 3, and one end of the driving shaft 5 is provided with a driven wheel 14, and the driven wheel 14 is connected to the driving wheel 16 through the linkage belt 15. The two driving wheels 16 are distributed from front to back, and the two driving wheels 16 are both arranged on the same rotating shaft. When the two driving wheels 16 rotate, under the connection of the linkage belt 15, the two driven wheels 14 distributed from top to bottom rotate synchronously, so as to achieve the purpose of driving the driving shaft 5 and the impeller 6 to rotate synchronously. The rotating shaft connected with the driving wheel 16 is arranged outside the frame 3, and the frame 3 is provided with a power motor 17 that can control the rotating shaft and the driving wheel 16 to rotate synchronously.

[0036] Embodiment 2:

[0037] like Figure 1-6 As shown, during the transmission process of the hand model, the reverse direction of its movement is mostly controlled by a transmission chain. The transmission chain and the hand model are mostly connected by swingable bearings and rotatable cams, so that the hand model can be flexibly rotated and enter different processing stations. A movable guide conveyor belt 7 is provided above the positioning pipe 1. The setting of the guide conveyor belt 7 can make the hand model entering the frame 3 in a horizontal state. When the hand model enters the designated position inside the frame 3, the direction of the hand model's fingers is facing the impeller 6. Two groups of symmetrically distributed electric rollers 8 are provided in the gap of the connecting pipe group 2. When the guide conveyor belt 7 moves away from the positioning pipe 1, the electric roller 8 can move to the position of the guide conveyor belt 7 to receive the hand model with a glove.

[0038] Specifically, in order to enable the guide conveyor belt 7 to move smoothly, a linkage frame 71 is provided on the side of the guide conveyor belt 7 away from the positioning pipe 1, a support frame 72 corresponding to the linkage frame 71 is provided in the frame 3, and a driving cylinder 73 is provided on the support frame 72 to control the linkage frame 71 and the guide conveyor belt 7 to move synchronously. When the guide conveyor belt 7 moves away from the positioning pipe 1, it moves away from the hand model in a horizontal state.

[0039] At the same time, the electric roller 8 is provided with a positioning plate 81 perpendicular to it, and multiple positioning plates 81 are arranged on the same extension frame 82. The extension frame 82 has a multi-section raised structure, and the raised structures are all located in the gap of the connecting pipe group 2. When the electric roller 8 and the extension frame 82 move to the original position of the guide conveyor belt 7, the electric roller 8 receives the hand model in a horizontal state.

[0040] After the electric roller 8 receives the hand model, the electric roller 8 rotates in place, and can drive the hand model to generate rotational motion. Therefore, in a low temperature environment, both sides of the hand model can be cooled quickly and evenly, further improving the efficiency of the cooling operation.

[0041] During the rotation of the hand mold, the fingers of the hand mold are facing the rotating impeller 6. Therefore, the airflow generated by the rotation of the impeller 6 can quickly cool the raw materials at the finger joints of the glove, effectively avoiding the phenomenon of incomplete cooling caused by the narrow finger joints that are prone to cooling dead corners, and further improving the quality of the cooling operation.

[0042] In order to enable the electric roller 8 to move smoothly, both ends of the extension frame 82 are provided with an alignment sleeve 83 that can move synchronously therewith, and the alignment sleeve 83 is provided with a follower bracket 84 that can move synchronously therewith. A support frame 2 85 distributed corresponding to the alignment sleeve 83 is provided in the frame 3, and the follower bracket 84 runs through the support frame 2 85. The support frame 2 85 is provided with a driving cylinder 2 86 that can control the synchronous movement of the extension frame 82, the alignment sleeve 83 and the follower bracket 84.

[0043] Embodiment 3:

[0044] like Figure 3-7 As shown, when the legs of the extension frame 82 are all inserted through the alignment sleeve 83 and the follower bracket 84, a driving motor 87 for controlling the rotation of the extension frame 82, the positioning plate 81 and the electric roller 8 is installed on one side of the two follower brackets 84 at the two legs of the extension frame 82. During the replacement and cleaning operation of the electric roller 8, the driving motor 87 can rotate the electric roller 8 to form a space for operating the electric roller 8, so as to facilitate the replacement and cleaning operation of the designated electric roller 8, thereby improving the portability during the operation.

[0045] Embodiment 4:

[0046] like Figure 1-7 As shown, in order to enable the two groups of cooling pipelines to be connected and the coolant to flow smoothly, one of the positioning pipelines 1 in the two groups of cooling pipelines is connected through a guide pipe 9. The positioning pipeline 1 in the cooling pipeline distributed downward that is not connected to the guide pipe 9 is provided with a liquid outlet pipe 10 extending to the outside of the frame 3, and the bottom end of the liquid outlet pipe 10 is connected to a collection rack 11, and the liquid outlet pipe 10 can discharge the coolant flowing through the two groups of cooling pipelines into the inside of the collection rack 11.

[0047] The collection rack 11 is provided with a delivery pipe 12, which extends to the inside of the rack 3, and the delivery pipe 12 is provided with an electric control pump 13, and the positioning pipe 1 in the cooling pipeline distributed above that is not connected to the guide pipe 9 is connected to the delivery pipe 12. Under the operation of the electric control pump 13, the coolant recovered in the collection rack 11 can enter the cooling pipeline again through the delivery pipe 12 to realize the circulation of the coolant. The low temperature environment inside the rack 3 can keep the cooling pipeline and the coolant in a low temperature state.

[0048] The two driving shafts 5 distributed from top to bottom are both arranged on the frame 3, and one end of the driving shaft 5 is provided with a driven wheel 14, and the driven wheel 14 is connected to the driving wheel 16 through a linkage belt 15. The two driving wheels 16 are distributed from front to back, and the two driving wheels 16 are both arranged on the same rotating shaft, and the rotating shaft is arranged outside the frame 3. A power motor 17 that can control the rotating shaft and the driving wheel 16 to rotate synchronously is arranged outside the frame 3.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
