Description

Technical Field

[0001] This utility model relates to the field of sheet processing technology, specifically to a sheet calendering device. Background Technology

[0002] In some plastic product processing technologies, raw materials are heated, mixed, filtered, and extruded, then pre-calendered. The intermediate sheet formed by pre-calendering is then circulated to a calender for further calendering to form a sheet of a specified width. Existing calenders include a frame with several calendering rolls and several sets of support rolls. The calendering rolls include a feed end roll group and a coating roll group. The feed end roll group includes a pair of first and second feed end calendering rolls spaced vertically apart, with the first feed end calendering roll positioned above the second feed end calendering roll. The coating roll group includes a first coating calendering roll arranged transversely to the second feed end calendering roll; the upper edge of the second feed end calendering roll is flush with the upper edge of the first coating calendering roll. Support rolls include a first set of support rolls positioned between the second feed end calendering roll and the first coating calendering roll, with the upper edge of the first set of support rolls flush with the upper edges of both the second feed end calendering roll and the first coating calendering roll. The calender has added a set of support rollers, which allows the sheet material blank to travel horizontally, avoiding the blank from moving downwards due to its own weight, thus affecting the quality of the sheet processing.

[0003] Existing calenders have the following problems: the edges of the calendered sheets need to be pre-cut, resulting in low production efficiency.

[0004] Based on the above situation, there is an urgent need for a sheet calendering device to solve the problem of low production efficiency. Utility Model Content

[0005] The purpose of this invention is to address the problem of low production efficiency in existing cutting machines, which require additional pre-cutting of the edges of the calendered sheets.

[0006] The technical solution of this utility model is as follows:

[0007] A sheet calendering apparatus, comprising:

[0008] A calendering mechanism, including calendering rolls and guide rolls disposed below the calendering rolls;

[0009] A cutting mechanism that contacts the guide roller and is used to cut the sheet;

[0010] Adjustment mechanism, connected to and adjusting the cutting position of the cutting mechanism;

[0011] The transport mechanism is located below the cutting mechanism.

[0012] Existing cutting machines require additional pre-cutting of the edges of the calendered sheet, resulting in low production efficiency. In this solution, the calendering mechanism calenders the intermediate sheet to form a sheet of a specified width. The cutting position of the cutting mechanism is adjusted by the adjusting mechanism to cut both ends of the sheet, facilitating subsequent bonding processes. The resulting scraps are transported to the pre-calendering equipment by the transport mechanism for reuse, saving material costs and solving the problem of low production efficiency.

[0013] Furthermore, this solution does not exclusively limit the specific structure of the cutting mechanism. One feasible solution is that the cutting mechanism includes two bases and cutting slices detachably mounted on the bases. The cutting slices are in contact with the guide rollers. When this solution is adopted, as the guide rollers rotate, the sheet material can be cut because the cutting slices are in contact with the guide rollers, and the width of the cut material can be adjusted by the spacing between the two cutting slices.

[0014] Furthermore, this solution is not limited to the specific structure of the adjustment mechanism. One feasible solution is that the adjustment mechanism includes a sleeve connected to the base and a guide rod passing through the base. A locking element is installed on the sleeve. When this solution is adopted, the cutting position of the cutting piece is adjusted by adjusting the position of the sleeve along the axial direction of the guide rod. After the adjustment is completed, the sleeve is fixed to the guide rod by the locking element to ensure that the cutting position remains fixed.

[0015] Furthermore, this solution does not exclusively limit the specific structure of the locking component. One feasible solution is that the locking component includes a bolt rod and a rotating rod connected to the bolt rod. When this solution is adopted, the bolt rod can be rotated by operating the rotating rod, which can conveniently and quickly fix or adjust the sleeve.

[0016] Furthermore, this solution does not exclusively limit the specific structure of the transport mechanism. One feasible solution is that the transport mechanism includes a first conveyor belt disposed below one of the bases and a second conveyor belt disposed parallel to the guide rollers. When this solution is adopted, the scrap material formed above the first conveyor belt falls directly onto the first conveyor belt. The scrap material formed on the side away from the first conveyor belt is transported to the first conveyor belt by the second conveyor belt. Then, the scrap material formed by the two-time cutting of the sheet is transported to the pre-calendering equipment for reuse by the first conveyor belt.

[0017] Furthermore, to prevent scrap materials from falling off the second conveyor belt, one feasible solution is to install a baffle on the second conveyor belt. With this solution, the scrap materials on the second conveyor belt can be prevented from falling off under the action of the baffle.

[0018] Compared with existing technologies, the beneficial effects of this utility model are:

[0019] 1. The calendering mechanism calenders the intermediate sheet to form a sheet of a specified width. The cutting position of the cutting mechanism is adjusted by the adjusting mechanism to cut both ends of the sheet to facilitate subsequent bonding processes. The scraps formed by cutting are transported to the precalendering equipment by the transport mechanism for reuse, saving material costs and solving the problem of low production efficiency.

[0020] 2. Since the cutting mechanism includes two bases and a cutting slice detachably mounted on the base, the cutting slice contacts the guide roller. As the guide roller rotates, the sheet material can be cut because the cutting slice contacts the guide roller, and the width of the cut material can be adjusted by the distance between the two cutting slices.

[0021] Third, since the adjustment mechanism includes a sleeve connected to the base and a guide rod passing through the base, and a locking element is installed on the sleeve, the cutting position of the cutting piece can be adjusted by adjusting the position of the sleeve along the axial direction of the guide rod. After the adjustment is completed, the sleeve is fixed to the guide rod by the locking element to ensure that the cutting position remains fixed. Attached Figure Description

[0034] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0035] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0036] Example:

[0037] Please refer to Figure 1 , Figure 2 and Figure 3 A sheet calendering apparatus, comprising:

[0038] The calendering mechanism 1 includes a calendering roller 11 and a guide roller 12 disposed below the calendering roller 11;

[0039] The cutting mechanism 2 contacts the guide roller 12 and is used to cut the sheet material;

[0040] Adjustment mechanism 3 connects to and adjusts the cutting position of cutting mechanism 2;

[0041] The transport mechanism 4 is located below the cutting mechanism 2.

[0042] Existing cutting machines require additional pre-cutting of the edges of the calendered sheet, resulting in low production efficiency. In this solution, the calendering mechanism 1 calenders the intermediate sheet to form a sheet of a specified width. The cutting position of the cutting mechanism 2 is adjusted by the adjusting mechanism 3, thereby cutting both ends of the sheet to facilitate subsequent bonding processes. The scraps formed by cutting are transported to the pre-calendering equipment by the transport mechanism 4 for reuse, saving material costs and solving the problem of low production efficiency.

[0043] Reference Figure 3This solution does not limit the specific structure of the cutting mechanism 2. One feasible solution is that the cutting mechanism 2 includes two bases 21 and a cutting slice 22 that is detachably installed on the bases 21. The cutting slice 22 is in contact with the guide roller 12. When this solution is adopted, as the guide roller 12 rotates, the sheet material can be cut because the cutting slice 22 is in contact with the guide roller 12, and the width after cutting can be adjusted by the distance between the two cutting slices 22.

[0044] Preferably, in this embodiment, the cutting slice 22 is a wood slice. When this solution is adopted, since the hardness of the wood slice is greater than that of the sheet material and less than that of the guide roller 12, cutting can be performed without scratching the guide roller 12.

[0045] Reference Figure 4 This solution does not limit the specific structure of the adjustment mechanism 3. One feasible solution is as follows: The adjustment mechanism 3 includes a sleeve 31 connected to the base 21 and a guide rod 32 passing through the base 21. A locking element 33 is installed on the sleeve 31. When this solution is adopted, the cutting position of the cutting piece 22 is adjusted by adjusting the position of the sleeve 31 along the axial direction of the guide rod 32. After the adjustment is completed, the sleeve 31 is fixed to the guide rod 32 by the locking element 33 to ensure that the cutting position remains fixed.

[0046] This solution does not limit the specific structure of the locking component 33. One feasible solution is that the locking component 33 includes a bolt rod 331 and a rotating rod 332 connected to the bolt rod 331. When this solution is adopted, the bolt rod 331 can be rotated by operating the rotating rod 332, which can conveniently and quickly fix or adjust the sleeve 31.

[0047] Reference Figure 2 This solution does not limit the specific structure of the transport mechanism 4. One feasible solution is that the transport mechanism 4 includes a first conveyor belt 41 located below one of the bases 21 and a second conveyor belt 42 arranged parallel to the guide roller 12. When this solution is adopted, the scrap material formed above the first conveyor belt 41 falls directly onto the first conveyor belt 41. The scrap material formed on the side away from the first conveyor belt 41 is transported to the first conveyor belt 41 by the second conveyor belt 42. Then, the scrap material formed by the two-time cutting of the sheet is transported to the pre-calendering equipment for reuse by the first conveyor belt 41.

[0048] Reference Figure 5 To prevent scrap materials from falling off the second conveyor belt 42, one feasible solution is to install a baffle 43 on the second conveyor belt 42. With this solution, the scrap materials on the second conveyor belt 42 can be prevented from falling off under the action of the baffle 43.

[0049] To address the issue of low production efficiency, this solution involves calendering the intermediate sheet using a calendering mechanism 1 to form a sheet of a specified width. The cutting position of the cutting mechanism 2 is adjusted using an adjusting mechanism 3, thereby cutting both ends of the sheet to facilitate subsequent bonding processes. The scraps generated from the cutting are transported to a pre-calendering equipment via a transport mechanism 4 for reuse, saving material costs and resolving the issue of low production efficiency.

[0050] To facilitate the cutting of the sheet material, in this solution, the cutting mechanism 2 includes two bases 21 and a cutting blade 22 detachably mounted on the bases 21. The cutting blade 22 contacts the guide roller 12. As the guide roller 12 rotates, the sheet material can be cut because the cutting blade 22 contacts the guide roller 12, and the width of the cut material can be adjusted by the spacing between the two cutting blades 22.

[0051] To facilitate adjustment of the cutting position of the cutting slice 22, in this solution, the adjustment mechanism 3 includes a sleeve 31 connected to the base 21 and a guide rod 32 passing through the base 21. A locking element 33 is installed on the sleeve 31. By adjusting the position of the sleeve 31 along the axial direction of the guide rod 32, the cutting position of the cutting slice 22 can be adjusted. After adjustment, the sleeve 31 is fixed to the guide rod 32 by the locking element 33 to ensure that the cutting position remains fixed.
