Technical Field
[0001] This utility model relates to the field of plastic processing technology, specifically to a drum molding device. Background Technology
[0002] In some plastic processing techniques, plastic granules are heated and pressed into sheets to form semi-finished products, which are then vulcanized using a drum vulcanizing machine. Existing drum vulcanizing machines include a machine body with an upper roller, a lower roller, and a vulcanizing drum on the front side. A conveyor roller is located at the rear of the machine body. The upper roller is mounted diagonally above the vulcanizing drum, the lower roller diagonally below it, and the conveyor roller is positioned behind the vulcanizing drum. A drive motor is mounted on the upper roller. A control box is located on the side of the machine body. The vulcanizing drum has a textured surface. Rubber products are fed into the vulcanizing drum by the lower roller and pressed against its textured surface. The vulcanized rubber products are then passed through the upper roller and exited by the conveyor roller. The aforementioned drum vulcanizing machine, with its textured vulcanizing drum, eliminates the need for padding belts in actual production, reducing production and labor costs; it also improves production speed and efficiency.
[0003] The existing drum vulcanizing machine has the following problems: because the vulcanizing drum is fixed, the wrap angle range of the semi-finished product on the vulcanizing drum is difficult to adjust, and the vulcanizing time can only be adjusted by adjusting the semi-finished product conveying rate.
[0004] Based on the above situation, there is an urgent need for a drum molding device to solve the problem of difficulty in adjusting the wrap angle range. Utility Model Content
[0005] The purpose of this invention is to address the problem that existing drum vulcanizing machines, due to the fixed setting of the vulcanizing drum, make it difficult to adjust the wrap angle range of the semi-finished product on the vulcanizing drum. The vulcanizing time can only be adjusted by adjusting the conveying speed of the semi-finished product, thus solving the problem of the difficulty in adjusting the wrap angle range.
[0006] The technical solution of this utility model is as follows:
[0007] A drupe molding apparatus, comprising:
[0008] A support frame on which an upper roller and a lower roller are mounted;
[0009] A vulcanizing drum is disposed between the upper roller and the lower roller, and the vulcanizing drum is connected to a movable shaft seat;
[0010] A steel strip is wrapped around the upper roller, lower roller, and vulcanizing drum;
[0011] The adjustment mechanism connects to and drives the movable shaft seat to move.
[0012] Existing drum vulcanizing machines, due to the fixed setting of the vulcanizing drum, make it difficult to adjust the wrap angle range of the semi-finished product on the vulcanizing drum. The vulcanization time can only be adjusted by adjusting the conveying speed of the semi-finished product. In this solution, the semi-finished product is conveyed to the vulcanizing drum and the steel belt for vulcanization by the upper roller. The adjustment mechanism drives the movable shaft seat and the vulcanizing drum to move synchronously to adjust the wrap angle range of the semi-finished product on the vulcanizing drum. This allows for more flexible adjustment of the vulcanization time and solves the problem of the difficulty in adjusting the wrap angle range.
[0013] Furthermore, this solution is not limited to the specific structure of the adjustment mechanism. One feasible solution is that the adjustment mechanism includes a lead screw passing through the movable shaft seat and a lead screw motor for driving the lead screw. When this solution is adopted, the lead screw is rotated by the lead screw motor, thereby causing the movable shaft seat to move along the axial direction of the lead screw. Due to the self-locking property of the lead screw structure, the adjusted movable shaft seat can remain stationary.
[0014] Furthermore, to make the movement of the movable bearing smoother, one feasible solution is that the adjustment mechanism further includes a guide rod passing through the movable bearing. When this solution is adopted, the movement of the movable bearing can be made smoother through the guiding effect of the guide rod.
[0015] Furthermore, to facilitate the adjustment of vulcanization pressure, one feasible solution is to install a tensioning mechanism on the bracket for adjusting the tension of the steel strip. When this solution is adopted, while the adjusting mechanism drives the movable shaft seat to move, the tensioning mechanism adjusts the tension of the steel strip to ensure that the vulcanization pressure during the vulcanization process is within a preset range.
[0016] Furthermore, this solution does not exclusively limit the specific structure of the tensioning mechanism. One feasible solution is that the tensioning mechanism includes a tensioning roller and a hydraulic cylinder connected to the tensioning roller. When this solution is adopted, the tensioning roller is moved by the hydraulic cylinder, thereby adjusting the tension of the steel strip.
[0017] Furthermore, to facilitate the adjustment of the conveying speed of the semi-finished product, one feasible solution is that the upper or lower roller is connected to a gearbox and a conveying motor is installed on the gearbox. When this solution is adopted, by cooperating with the gearbox and the adjustment mechanism, the vulcanization time can be adjusted by adjusting the wrap angle range under the preset conveying speed conditions, thereby adjusting the degree of vulcanization to ensure that the performance of the vulcanized material is qualified.
[0018] Compared with existing technologies, the beneficial effects of this utility model are:
[0019] 1. The semi-finished product is conveyed to the vulcanizing drum and the steel strip through the upper roller for vulcanization. The adjustment mechanism drives the movable shaft seat and the vulcanizing drum to move synchronously to adjust the wrap angle range of the semi-finished product on the vulcanizing drum. This allows for more flexible adjustment of the vulcanization time and solves the problem of difficulty in adjusting the wrap angle range.
[0020] Second, since the adjustment mechanism includes a lead screw passing through the movable shaft seat and a lead screw motor for driving the lead screw, the lead screw motor drives the lead screw to rotate, thereby causing the movable shaft seat to move along the axial direction of the lead screw. Due to the self-locking property of the lead screw structure, the adjusted movable shaft seat can remain stationary.
[0021] Third, since the bracket is equipped with a tensioning mechanism for adjusting the tension of the steel strip, while the adjusting mechanism drives the movable shaft seat to move, the tension of the steel strip is adjusted by the tensioning mechanism to ensure that the vulcanization pressure during the vulcanization process is within the preset range.

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.
[0033] The features and performance of this utility model will be further described in detail below with reference to the embodiments.
[0034] Example:
[0035] Please refer to Figure 1 , Figure 2 and Figure 3 A drupe molding apparatus, comprising:
[0036] Support 1, on which upper roller 2 and lower roller 3 are mounted;
[0037] A vulcanizing drum 4 is located between the upper roller 2 and the lower roller 3, and a movable shaft seat 5 is connected to the vulcanizing drum 4.
[0038] Steel strip 6 is wrapped around the upper roller 2, lower roller 3 and vulcanizing drum 4;
[0039] Adjustment mechanism 7 connects to and drives the movable shaft seat 5 to move.
[0040] Existing drum vulcanizing machines, due to the fixed setting of the vulcanizing drum, make it difficult to adjust the wrap angle range of the semi-finished product on the vulcanizing drum. The vulcanization time can only be adjusted by adjusting the conveying speed of the semi-finished product. In this solution, the semi-finished product is conveyed to the vulcanizing drum and the steel belt 6 by the upper roller 2 for vulcanization. The adjusting mechanism 7 drives the movable shaft seat 5 and the vulcanizing drum 4 to move synchronously to adjust the wrap angle range of the semi-finished product on the vulcanizing drum 4. This allows for more flexible adjustment of the vulcanization time and solves the problem of the difficulty in adjusting the wrap angle range.
[0041] Reference Figure 2 and Figure 4This solution does not limit the specific structure of the adjustment mechanism 7. One feasible solution is that the adjustment mechanism 7 includes a lead screw 71 that passes through the movable shaft seat 5 and a lead screw motor 72 for driving the lead screw 71. When this solution is adopted, the lead screw motor 72 drives the lead screw 71 to rotate, thereby causing the movable shaft seat 5 to move along the axial direction of the lead screw 71. Due to the self-locking property of the lead screw structure, the adjusted movable shaft seat 5 can remain stationary.
[0042] To make the movement of the movable bearing 5 smoother, one feasible solution is that the adjusting mechanism 7 also includes a guide rod 73 passing through the movable bearing 5. When this solution is adopted, the movement of the movable bearing 5 can be made smoother through the guiding effect of the guide rod 73.
[0043] Reference Figure 2 To facilitate the adjustment of vulcanization pressure, one feasible solution is to install a tensioning mechanism 8 on the bracket 1 for adjusting the tension of the steel strip 6. When this solution is adopted, while the adjusting mechanism 7 drives the movable shaft seat 5 to move, the tension of the steel strip 6 is adjusted by the tensioning mechanism 8 to ensure that the vulcanization pressure during the vulcanization process is within the preset range.
[0044] Reference Figure 3 and Figure 5 This solution does not limit the specific structure of the tensioning mechanism 8. One feasible solution is that the tensioning mechanism 8 includes a tensioning roller 81 and a hydraulic cylinder 82 connected to the tensioning roller 81. Specifically, in this embodiment, the hydraulic cylinder 82 is connected to a cylinder bearing 83 and the tensioning roller is mounted on the cylinder bearing 83. When this solution is adopted, the tensioning roller 81 is moved by the hydraulic cylinder 82, thereby adjusting the tension of the steel belt 6.
[0045] Reference Figure 2 To facilitate the adjustment of the conveying speed of the semi-finished products, one feasible solution is: the upper roller 2 or the lower roller 3 is connected to a gearbox 21 and a conveying motor 22 is installed on the gearbox 21. When this solution is adopted, by cooperating with the adjustment mechanism 7 through the gearbox 21, the vulcanization time can be adjusted by adjusting the wrap angle range under the preset conveying speed conditions, thereby adjusting the degree of vulcanization, so as to ensure that the performance of the vulcanized material is qualified.
[0046] To address the difficulty in adjusting the wrap angle range, this solution involves conveying the semi-finished product to the vulcanizing drum and steel belt 6 via the upper roller 2 for vulcanization. The adjusting mechanism 7 drives the movable shaft seat 5 and the vulcanizing drum 4 to move synchronously, thereby adjusting the wrap angle range of the semi-finished product on the vulcanizing drum 4. This allows for more flexible adjustment of the vulcanization time and solves the problem of difficulty in adjusting the wrap angle range.
[0047] In order to keep the adjusted movable bearing 5 stationary, in this scheme, the adjusting mechanism 7 includes a lead screw 71 passing through the movable bearing 5 and a lead screw motor 72 for driving the lead screw 71. The lead screw motor 72 drives the lead screw 71 to rotate, thereby causing the movable bearing 5 to move along the axial direction of the lead screw 71. Due to the self-locking property of the lead screw structure, the adjusted movable bearing 5 can be kept stationary.
[0048] In order to adjust the tension of the steel strip 6, in this scheme, since the bracket 1 is equipped with a tensioning mechanism 8 for adjusting the tension of the steel strip 6, while the adjusting mechanism 7 drives the movable shaft seat 5 to move, the tension of the steel strip 6 is adjusted by the tensioning mechanism 8 to ensure that the vulcanization pressure during the vulcanization process is within the preset range.
