Description

Technical Field

[0001] The present application belongs to the field of paper cup machines, and more specifically, to a knurled outer mold structure of a paper cup machine. Background Art

[0002] When the paper cup machine is producing single-sided coated paper cups, the knurled outer mold needs to be heated to promote the adhesion of the bottom of the paper cup. When producing double-sided coated paper cups, it needs to be replaced with a knurled outer mold with cooling capability to prevent the coating on the outside of the paper cup from being scratched.

[0003] The traditional knurled outer mold usually has a cooling groove on the knurled outer groove, and then the cooling groove is sealed and coolant is passed into the cooling groove. When heating is required, the knurled outer mold with heating function is replaced. The replacement process of this structure is time-consuming and labor-intensive because the position of the knurled outer mold needs to be recalibrated. At the same time, the sealing path on the cooling groove is long, which also has the risk of poor sealing and coolant leakage, affecting the production efficiency of the paper cup machine; therefore, it is necessary to solve the above technical problems. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a knurled outer mold structure for a paper cup machine to solve the technical problem of low replacement efficiency of the knurled outer mold in the prior art.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is: to provide a knurled outer mold structure of a paper cup machine, comprising:

[0006] A body, forming a through hole and a channel ringed around the through hole;

[0007] A heat conducting member, at least a portion of which is accommodated in the channel and abuts against the body, and the channel forms an opening in the radial direction for the heat conducting member to be separated;

[0008] The cover is detachably connected to the main body and is used to close at least a portion of the opening that enables the heat conducting member to be kept in the channel.

[0009] Optionally, the channel has an arc segment arranged around the through hole and straight line segments extending from both ends of the arc segment to the edge of the body respectively;

[0010] Both ends of the heat conducting member extend from the straight section to the outside of the body.

[0011] Optionally, the arc segment of the channel is coaxially arranged with the through hole.

[0012] Optionally, the body forms an avoidance groove between the two straight line segments.

[0013] Optionally, the cover is adapted to the shape of the arc segment and is used to close the opening of the arc segment portion.

[0014] Optionally, the cover has a flat structure and is flatly attached to the body along a thickness direction.

[0015] Optionally, the cover body is connected to the main body via a plurality of fastening bolts, and the plurality of fastening bolts are evenly distributed along an extension direction of the cover body.

[0016] Optionally, the channel has an inner wall surface adapted to the shape of the heat conductor and entirely abutting against the heat conductor.

[0017] Optionally, the heat-conducting member is a cooling tube, and an end of the cooling tube is connected to a quick connector for quick connection with an external infusion pipeline.

[0018] Optionally, the heat conducting member is an electric heating tube.

[0019] The knurled outer mold structure of the paper cup machine provided in the present application has the beneficial effect that: compared with the prior art, in the knurled outer mold structure of the paper cup machine of the present application, a through hole and a channel arranged around the through hole are formed on the body. At least a part of the heat conductor is accommodated in the channel and abuts against the body, the heat conductor can be separated from the channel from the opening arranged on the side wall of the channel, and the interior of the heat conductor can be used to pass the cooling liquid. In this way, when the knurled outer mold structure of the paper cup machine provided in the present application is used to produce a single-sided coated paper cup, the cooling liquid can flow in the heat conductor and the cover body connected to the body and used to close the opening of the channel only needs to play the role of keeping the heat conductor in the channel without being used to seal the channel, which is not only conducive to ensuring that the cooling liquid will not leak, but also when the knurled outer mold needs to be heated, it is only necessary to remove the cover body and replace the cooling tube with an electric heating tube, without reassembling the knurled outer mold, which can significantly improve the replacement efficiency of the knurled outer mold in this embodiment when making paper cups with different raw materials, which is far better than the prior art.

[0029] The main body 101 forms a through hole 102 and a channel 103 arranged around the through hole 102. At least a portion of the heat conductor 104 is accommodated in the channel 103 and abuts against the main body 101. The channel 103 forms an opening along the radial direction for the heat conductor 104 to detach. The cover 105 is detachably connected to the main body 101 and is used to close at least a portion of the opening of the channel 103 so as to keep the heat conductor 104.

[0030] In the knurled outer mold structure of the paper cup machine provided in this embodiment, a through hole 102 and a channel 103 arranged around the through hole 102 are formed on the body 101; at least a part of the heat conductive member 104 is accommodated in the channel 103 and abuts against the body 101, and the heat conductive member 104 can be detached from the channel 103 through an opening arranged on the side wall of the channel 103 and the interior of the heat conductive member 104 can be used to pass cooling liquid. In this way, when the knurled outer mold structure of the paper cup machine provided in this embodiment is producing single-sided coated paper cups, the coolant can flow in the heat conductive member 104 and the cover body 105 connected to the main body 101 and used to close the open channel 103 only needs to keep the heat conductive member 104 in the channel 103, and does not need to be used to seal the channel 103. This is not only conducive to ensuring that the coolant does not leak, but also when the knurled outer mold needs to be heated, it is only necessary to remove the cover body and replace the cooling tube with an electric heating tube without reassembling the knurled outer mold. This can significantly improve the replacement efficiency of the knurled outer mold in this embodiment when making paper cups with different raw materials, which is far superior to the prior art.

[0033] In another embodiment of the present application, please refer to Figure 1 and Figure 2The body 101 forms an avoidance groove 108 between the two straight segments 107. According to the above structure provided in this embodiment, the avoidance groove 108 provided on the body 101 is beneficial to reducing the weight of the knurling outer mold structure in this embodiment on the one hand; on the other hand, it is beneficial to saving the time required for cooling the body 101 and improving the replacement efficiency of the knurling outer mold in this embodiment.

[0034] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The cover 105 is adapted to the shape of the arc segment 106 and is used to close the opening of the arc segment 106. According to the above structure provided in this embodiment, the cover 105 can not only stably support the heat conductor 104 inside the channel 103, but also help to reduce its own weight, thereby reducing the manufacturing cost of the knurled outer mold structure provided in this embodiment.

[0035] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The cover 105 is flat and is flatly attached to the body 101 along the thickness direction. According to the above structure provided in this embodiment, the cover 105 with a flat structure is not only conducive to reducing the manufacturing cost of the knurled outer mold structure provided in this embodiment, but also conducive to more stably connecting to the body 101, thereby improving the installation stability of the heat conducting member 104.

[0036] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The cover 105 is connected to the body 101 by a plurality of fastening bolts 109, and the plurality of fastening bolts 109 are evenly distributed along the extension direction of the cover 105. According to the above structure provided in this embodiment, the plurality of evenly distributed fastening bolts 109 are conducive to more stably connecting the cover 105 to the body 101, thereby further improving the installation stability of the heat conducting member 104.

[0037] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The channel 103 has a shape that is adapted to the shape of the heat conductor 104 and is completely in contact with the inner wall surface of the heat conductor 104.
