Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to an auxiliary device for an extruder. Background Art

[0002] In some plastic product processing techniques, materials are filtered through an extruder to form strips, which are then rolled into sheets. Existing extruders include a housing, a hopper fixedly connected to the top of the housing, a filter fixedly connected within the hopper, a first roller rotatably sleeved on the filter, a rotating rod fixedly connected to the top of the first roller, the rotating rod engaging the filter, a first bevel gear fixedly connected to the bottom end of the first roller, a second bevel gear meshing with the first bevel gear, a second roller fixedly connected to one side of the second bevel gear, and a third bevel gear fixedly connected to one end of the second roller. The extruder can rotate the first bevel gear and the first roller via the second bevel gear. When the rotating rod on the first roller rotates, the material on the filter is continuously moved to prevent the filter from being clogged.

[0003] Existing extruders have the following problems: since some sheets are relatively wide, it is inconvenient for the calendering equipment to calender the strip material at one time and form a sheet of a specified width.

[0004] Based on the above situation, there is an urgent need for an extruder auxiliary device to solve the problem that it is difficult to calender and form a sheet of a specified width in one go. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the calendering equipment is not convenient for calendering the strip material into a sheet of a specified width at one time because some sheets are large in width in the existing extruder.

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

[0007] An extruder auxiliary device, comprising:

[0008] The pre-calendering mechanism is used to receive the strip material discharged from the extruder and perform pre-calendering;

[0009] A fixed conveyor belt is arranged below the pre-calendering mechanism;

[0010] A movable bracket is provided at the unloading end of the fixed conveyor belt, and a movable conveyor belt is installed on the movable bracket;

[0011] The driving mechanism is connected to and drives the movable bracket to swing back and forth.

[0012] In the existing extruder, since some sheets are large in width, it is not convenient for the calendering equipment to calender the strip material at one time and form a sheet of a specified width. In this solution, the strip material discharged from the extruder is pre-calendered by the pre-calendering mechanism, and then the fixed conveyor belt transports the material to the movable conveyor belt. The driving mechanism drives the movable bracket and the movable conveyor belt to swing back and forth, so that the material is circulated to the calendering mechanism within the specified width range of the sheet, and the calendering mechanism can process the material into a sheet of a specified width at one time, which solves the problem that the calendering equipment is not convenient to calender the strip material at one time and form a sheet of a specified width, and improves the calendering efficiency.

[0013] Furthermore, this solution does not solely limit the specific structure of the pre-calendering mechanism. One feasible solution is: the pre-calendering mechanism includes two transmission-connected pre-calendering rollers, one of which is connected to a pre-calendering motor. When this solution is adopted, the two pre-calendering rollers are driven to rotate by the pre-calendering motor, thereby pre-calendering the strip material.

[0014] Furthermore, since the movable bracket will bend the material, in order to avoid the material from breaking, one feasible solution is: the pre-calendering mechanism also includes a dividing piece in contact with one of the pre-calendering rollers. When this solution is adopted, the width of the material is cut by the dividing piece, which can avoid the material from breaking during the bending process.

[0015] Furthermore, this solution does not solely limit the specific structure of the driving mechanism. One feasible solution is: the driving mechanism includes a crank and a toggle rod is formed on the crank, a bar hole is formed on the movable bracket and the toggle rod is arranged in the bar hole. When this solution is adopted, the circular motion can be converted into reciprocating swing of the movable bracket through the crank.

[0016] Furthermore, in order to facilitate the adjustment of the swing speed of the movable bracket, one feasible solution is: the crank is installed on the low-speed shaft of the transmission and the transmission is connected to a drive motor. When this solution is adopted, the transmission ratio is adjusted by the transmission, thereby adjusting the swing speed of the movable bracket.

[0017] Furthermore, in order to reduce the wear of the toggle rod, one feasible solution is that a sleeve is rotatably connected to the toggle rod. When this solution is adopted, the wear of the toggle rod can be reduced due to rolling friction between the sleeve and the strip hole.

[0018] Compared with the existing technology, the beneficial effects of the present invention are:

[0019] First, the strip material discharged from the extruder is pre-calendered by the pre-calendering mechanism, and then the fixed conveyor belt transports the material to the movable conveyor belt. The driving mechanism drives the movable bracket and the movable conveyor belt to swing back and forth, thereby circulating the material to the calendering mechanism within the specified width range of the sheet. The calendering mechanism can process the material into a sheet of a specified width at one time, solving the problem that the calendering equipment is inconvenient to calender the strip material into a sheet of a specified width at one time, thereby improving the calendering efficiency;

[0020] Second, since the pre-calendering mechanism further includes a splitter in contact with one of the pre-calendering rollers, the width of the material is cut by the splitter, thereby preventing the material from breaking during the bending process;

[0021] 3. Since the driving mechanism includes a crank and a toggle rod is formed on the crank, a strip hole is formed on the movable bracket and the toggle rod is arranged in the strip hole, the circular motion can be converted into the reciprocating swing of the movable bracket through the crank.

[0036] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0037] Example:

[0038] Please refer to Figure 1 and Figure 2 , an extruder auxiliary device, comprising:

[0039] The pre-calendering mechanism 1 is used to receive the strip material discharged from the extruder and perform pre-calendering;

[0040] A fixed conveyor belt 2 is arranged below the pre-calendering mechanism 1;

[0041] The movable bracket 3 is provided at the unloading end of the fixed conveyor belt 2, and a movable conveyor belt 31 is installed on the movable bracket 3;

[0042] The driving mechanism 4 is connected to and drives the movable bracket 3 to swing back and forth;

[0043] The pre-calendering mechanism 1 , the fixed conveyor belt 2 , the movable bracket 3 and the driving mechanism 4 are all installed on the base 5 .

[0044] In the existing extruder, since some sheets are large in width, the calendering equipment is not convenient for calendering the strip material at one time and forming a sheet of a specified width. In this solution, the strip material discharged from the extruder is pre-calendered by the pre-calendering mechanism 1, and then the fixed conveyor belt 2 transports the material to the movable conveyor belt 31, and the driving mechanism 4 drives the movable bracket 3 and the movable conveyor belt 31 to swing back and forth, so that the material is circulated to the calendering mechanism within the specified width range of the sheet, which enables the calendering mechanism to process the material into a sheet of a specified width at one time, thereby solving the problem that the calendering equipment is not convenient for calendering the strip material at one time and forming a sheet of a specified width, and improving the calendering efficiency.

[0045] This solution does not limit the specific structure of the pre-calendering mechanism 1. One feasible solution is: the pre-calendering mechanism 1 includes two pre-calendering rollers 11 connected by transmission, one of the pre-calendering rollers 11 is connected to a pre-calendering motor 12. Specifically, in this embodiment, the two pre-calendering rollers 11 are driven by gear transmission. When this solution is adopted, the pre-calendering motor 12 drives the two pre-calendering rollers 11 to rotate synchronously, thereby pre-calendering the strip material.

[0046] Reference Figure 3 Since the movable bracket 3 will bend the material, in order to avoid the material from breaking, one feasible solution is: the pre-calendering mechanism 1 also includes a splitting piece 13 in contact with one of the pre-calendering rollers 11. When this solution is adopted, the width of the material is cut by the splitting piece 13, which can avoid the material from breaking during the bending process.

[0047] Preferably, in order to facilitate the installation and fixation of the split piece 13, one feasible solution is: a mounting rod 51 is formed on the base 5 and the mounting rod 51 is passed through the split piece 13, and a nut 52 is installed on the mounting rod 51. When this solution is adopted, the split piece 13 can be easily installed and fixed by operating the nut 52.

[0048] Reference Figure 5 Preferably, in order to facilitate the adjustment of the split piece 13, one feasible solution is that an adjustment hole 131 is formed on the split piece 13. When this solution is adopted, the installation position of the split piece 13 can be adaptively adjusted.

[0049] Reference Figure 4 This solution does not limit the specific structure of the driving mechanism 4. One feasible solution is: the driving mechanism 4 includes a crank 41 and a toggle rod 42 is formed on the crank 41, a bar hole 32 is formed on the movable bracket 3 and the toggle rod 42 is arranged in the bar hole 32. When this solution is adopted, the circular motion can be converted into the reciprocating swing of the movable bracket 3 through the crank 41.

[0050] In order to facilitate the adjustment of the swing speed of the movable bracket 3, one feasible solution is: the crank 41 is installed on the low-speed shaft of the transmission 43 and the transmission 43 is connected to the drive motor 44. When this solution is adopted, the transmission ratio is adjusted by the transmission 43, thereby adjusting the swing speed of the movable bracket 3.

[0051] In order to reduce the wear of the toggle rod 42, one feasible solution is that a sleeve 421 is rotatably connected to the toggle rod 42. When this solution is adopted, the wear of the toggle rod 42 can be reduced due to rolling friction between the sleeve 421 and the strip hole 32.

[0052] In order to solve the problem that the calendering equipment is not convenient for calendering the strip material and forming a sheet of a specified width at one time, in this solution, the strip material discharged from the extruder is pre-calendered by the pre-calendering mechanism 1, and then the fixed conveyor belt 2 transports the material to the movable conveyor belt 31, and the driving mechanism 4 drives the movable bracket 3 and the movable conveyor belt 31 to swing back and forth, so that the material is circulated to the calendering mechanism within the specified width range of the sheet, and the calendering mechanism can process the material into a sheet of a specified width at one time, which solves the problem that the calendering equipment is not convenient for calendering the strip material and forming a sheet of a specified width at one time, and improves the calendering efficiency.

[0053] In order to avoid material breakage, in this solution, since the pre-calendering mechanism 1 further includes a splitter 13 in contact with one of the pre-calendering rollers 11, the width of the material is cut by the splitter 13, which can avoid breakage during the bending process of the material.

[0054] In order to make the movable bracket 3 swing back and forth, in this solution, since the driving mechanism 4 includes a crank 41 and a toggle rod 42 is formed on the crank 41, a bar hole 32 is formed on the movable bracket 3 and the toggle rod 42 is arranged in the bar hole 32, the circular motion can be converted into the reciprocating swing of the movable bracket 3 through the crank 41.
