Description

Technical Field

[0001] The present invention relates to the field of film processing, and particularly to a machete device. Background Art

[0002] The transverse stretching temperature of a double-drawn polyester film production line is very high, usually at 240 degrees Celsius. On the one hand, it is necessary to keep the film at a high temperature of 240 degrees Celsius. On the other hand, it is necessary to cool the chain clips to avoid the high temperature at the chain clip part, which easily causes the film to adhere to the chain clip and result in film breakage. For example, in the comparative document with the Chinese patent publication number CN203919695U, it directly blows cold air on the chain clips for cooling, which will inevitably affect the processing temperature required for the film in the oven; if relatively cold pipes such as water-cooled pipes are used to approach the chain clips to achieve the purpose of heat exchange, since the chain clips are moving, it is difficult for the water-cooled pipes to keep in contact with the chain clips, and such heat exchange efficiency is not high enough to achieve an ideal heat exchange effect.

The various technical features in the present invention can be interactively combined without conflicting with each other.

[0023] Referring to Figures 1 to 4 , a chain clip cooling device includes an oven 1, a rack 2 disposed in the horizontal drawing oven 1, and two chain clip assemblies disposed on the rack 2. Each chain clip assembly includes a bracket 31 disposed on the rack 2, a chain 32, and a plurality of chain clips 33 disposed on the chain 32. The chain clips 33 are used to clamp the film. A partition block 4 is provided on each bracket 31. The partition block 4 extends in the left-right direction. Each chain 32 extends in the left-right direction and surrounds the partition block 4 end to end. The chain 32 and the partition block 4 are arranged in one-to-one correspondence. A cooling cover 8 is provided on each bracket 31. The cooling cover 8 is fixedly connected to the bracket 31. A cooling channel is formed between the cooling cover 8 and the partition block 4. The chain 32 passes through the cooling channel in one-to-one correspondence. The two cooling channels are disposed on the mutually facing sides of the two partition blocks 4. An air inlet pipe 6 and an air outlet pipe 7 are provided on the cooling cover 8. One end of the air inlet pipe 6 communicates with the outside of the oven 1, and the other end communicates with the cooling channel. One end of the air outlet pipe 7 communicates with the outside of the oven 1, and the other end communicates with the cooling channel.

[0024] As described above, during use, the chain 32 on the mutually facing sides of the partition blocks 4 drives the chain clips 33 to perform a return movement, and the chain 32 on the mutually facing sides of the partition blocks 4 drives the chain clips 33 to perform a forward movement. The chain clips 33 are used to clamp the film. The chain clips 33 in the forward movement section clamp the film. There are multiple temperature zones in the oven 1 and a certain predetermined temperature is maintained according to the preset of the user; the partition blocks 4 separate the forward movement section and the return movement section of the chain 32, so that the chain clips 33 in the return movement section can be cooled separately, avoiding affecting the temperature of the film clamped by the chain clips 33 in the forward movement section. The cooling channel formed between the cooling cover 8 and the partition blocks 4 can be used to cool the chain 32 performing the return movement and the chain clips 33 on the chain 32, effectively avoiding the temperature of the chain clips 33 from being too high. At the same time, through the setting of the cooling cover 8, it can effectively avoid the heat exchange of the air inlet pipe 6 and the air outlet pipe 7 with the chain 32 and the chain clips 33 in the return movement section from having a greater impact on the temperature in the oven 1. Moreover, by setting the air inlet pipe 6 and the air outlet pipe 7, the user connects a fan to the air inlet pipe 6 and / or connects a fan to the air outlet pipe 7, so that an air flow is formed in the cooling cover 8. On the one hand, the heat exchange effect on the chain clips 33 and the chain 32 is better, and on the other hand, the impact on the temperature in the oven 1 can be reduced.

[0025] The above-mentioned forward movement refers to the movement from the upstream of processing to the downstream of processing, the return movement refers to the movement from the downstream of processing to the upstream of processing, the above-mentioned forward movement section refers to the travel section of the forward movement, and the above-mentioned return movement section refers to the travel section of the return movement.

The lengths of the upper horizontal plate 41, the vertical plate 43, and the lower horizontal plate 42 extend in the left-right direction. The chain 32 is disposed between the upper horizontal plate 41 and the lower horizontal plate 42, and the chain 32 surrounds the vertical plate 43. Through this I-shaped arrangement, its structure is stable. In addition, the vertical plate 43 can separate the chains 32 and chain clips 33 in the process section and the return section, avoiding the influence of the cooling air flow on the chains 32 and chain clips 33 in the process section. At the same time, through the arrangement of the upper horizontal plate 41 and the lower horizontal plate 42, on the one hand, a space cooperating with the cooling cover 8 can be formed, which is convenient to use and facilitates the installation of the cooling cover 8. On the other hand, the upper horizontal plate 41 and the lower horizontal plate 42 can further prevent the air flow for cooling the chains 32 and chain clips 33 in the return section from flowing too much to the outside.

[0032] As a further preferred embodiment, a raised edge 421 is provided on the top surface of the lower horizontal plate 42. The raised edge 421 extends in the left-right direction and is provided at the edge of the lower horizontal plate 42 close to the cooling cover 8.

In some embodiments, the user can use this embodiment in combination with the above-mentioned embodiments of the groove 411 and the clamping edge 84. Through the arrangement of the buckle and the raised edge 421, the connection between the lower horizontal plate 42 and the bottom plate 83 can be facilitated.

[0033] Further as a preferred embodiment, the air inlet pipe 6 and the air outlet pipe 7 are fixedly connected to the back plate 82. This structure is simple and convenient to set up. In some embodiments, the air inlet and the air outlet are provided on the back plate 82, and the back plate 82 faces the chain 32 and the chain clip 33 between the upper horizontal plate 41 and the lower horizontal plate 42. Thus, the user can connect a blower for blowing air to the air inlet on the back plate 82, so that the air blown out from the air outlet can directly blow towards the chain clip 33 and the chain 32. In addition, by providing the air outlet on the back plate 82, the user can connect a blower for exhausting air to the air outlet, thereby facilitating the formation of an air gate for exhausting air and reducing the cooling air in the cooling hood 8 from entering the oven 1.

A tension spring 9 is provided between the connecting plate and the first block 422, and two ends of the tension spring 9 are respectively connected to the connecting plate and the first block 422. This structure is simple and convenient to set up. Through the setting of the tension spring 9, a pre-tightening force generated by the tension spring 9 can be continuously generated between the connecting plate and the first block 422, making the connection between the cooling hood 8 and the partition block 4 more stable. In addition, the connecting plate is connected to the bottom plate 83 by screws, which is convenient for installation and disassembly.

The air inlet pipes 6 communicating with the two cooling channels are arranged in a mirror image of each other, and the air outlet pipes 7 communicating with the two cooling channels are arranged in a mirror image of each other.
