Description

Technical Field

[0001] The present application relates to the technical field of a polytetrafluoroethylene film degreasing and stretching oven, and in particular to a feeding mechanism of the degreasing and stretching oven. Background Art

[0002] The degreasing and stretching oven is an oven with degreasing and stretching structure and function, which is mainly used for heating, degreasing and stretching of materials in the degreasing and stretching process. The degreasing and stretching oven can evenly control the temperature inside the oven to ensure that the material is evenly heated during the degreasing and stretching process to achieve the expected degreasing and stretching effect.

[0003] In the field of medical beauty prostheses, expanded polytetrafluoroethylene is often used as a material for making prostheses. When making a prosthesis with an expanded polytetrafluoroethylene film, it is necessary to first use a degreasing stretching oven to deoil and stretch the film material. In the related art, the degreasing stretching oven includes an oven body, a unwinding roller and a winding roller, and the unwinding roller and the winding roller are rotatably installed at the feed port and the discharge port of the oven body, respectively. When in use, the film coil is installed on the unwinding roller, and then the film is passed through the oven, and after being deoiled, stretched, and dried in the oven, it is wound on the winding roller.

[0004] In actual production, it is found that when the previous roll of film is unwound, another roll of film needs to be replaced in time. In the process of replacing the film roll, a material table needs to be placed on the side of the unwinding roller, and the film roll to be loaded is placed on the workbench. When the previous roll of film is almost used up, the film on the material table is connected with the film being loaded, and then the new film roll is replaced. The whole process requires placing a material table on the side of the unwinding roller of the degreasing stretching oven, which takes up a lot of space and is inconvenient to use. Utility Model Content

[0005] In order to improve the problem that the material table occupies space and is inconvenient to use, the present application provides a loading mechanism for a degreasing stretching oven.

[0006] The present application provides a feeding mechanism for a degreasing stretching oven, which adopts the following technical solution:

[0007] A feeding mechanism of a degreasing stretching oven comprises a machine body, an unwinding roller and a damper, and also comprises a material table and a folding assembly, wherein the material table is connected to a side wall of the machine body through the folding assembly;

[0008] The folding assembly includes a folding rod, a support rod, a fixed rod and a locking structure, wherein the fixed rod is vertically fixed on the side wall of the machine body; the folding rod is rotatably mounted on the fixed rod and the rotation axis is perpendicular to the length direction of the fixed rod, and the material table is fixed on the folding rod; one end of the support rod is rotatably connected to the fixed rod, and the other end of the support rod is slidably set on the folding rod; the locking structure is set on the folding rod, and is used to lock the position of the support rod.

[0009] By adopting the above technical solution, the material platform can be opened or folded to one side of the machine body through the folding assembly to achieve flexible use of space. In the process of opening the material platform, the material platform drives the folding rod to rotate. Since one end of the support rod is rotatably connected to the fixed rod, the other end of the support rod slides on the folding rod during the process of the folding rod rotating and opening. When the material platform is rotated to a horizontal position, the position of the support rod on the folding rod is locked by the locking structure, thereby achieving horizontal fixation of the material platform. When the material platform needs to be folded, the locking structure is released from the locking of the sliding end of the support rod, and the sliding end of the support rod can slide freely on the folding rod. Then the material platform is rotated to make the sliding end of the support rod slide to the end of the folding rod away from the fixed rod, so that the material platform is folded to one side of the machine body, thereby effectively reducing the space occupied by the material platform and facilitating operation.

[0010] Preferably, a slide groove is provided on the folding rod, and the length direction of the slide groove is parallel to the length direction of the folding rod; a slide rod is fixed to one end of the support rod close to the folding rod, and the slide rod is slidably installed in the slide groove along the length direction of the slide groove.

[0011] By adopting the above technical solution, a sliding groove is opened on the folding rod, the sliding rod is fixed on the supporting rod, and the sliding rod is slidably installed in the sliding groove. During use, the sliding rod will slide along the sliding groove to realize the sliding connection between the supporting rod and the folding rod; at the same time, the sliding rod slides along the sliding groove, which can improve the position accuracy of the sliding rod on the folding rod.

[0012] Preferably, the locking structure includes a locking plate and an elastic member, the locking plate is rotatably mounted on the folding rod, and the rotation axis of the locking plate is perpendicular to the length direction of the slide groove; the elastic member connects the folding rod and the locking plate, so that one end of the locking plate close to the fixed rod elastically abuts against the folding rod; the slide groove is located at one end of the folding rod away from the fixed rod, and a locking gap is formed between one end of the folding rod that the locking plate abuts against and the side wall of the end of the slide groove to lock the slide rod.

[0013] By adopting the above technical solution, the locking piece is rotatably mounted on the folding rod, and one end of the locking piece close to the fixed rod is elastically abutted against the folding rod through an elastic member, so that a locking gap is formed between the locking piece and the side wall of the end of the chute; when the sliding rod slides to the end of the chute close to the fixed rod, the sliding rod falls into the locking gap, and at this time, the end of the locking piece abuts against the sliding rod to lock the position of the support rod. When it is necessary to release the locking of the support rod, press one end of the locking piece away from the fixed rod, and the locking piece rotates around the rotating shaft, so that the sliding rod disengages from the locking gap, and the sliding rod can slide in the chute, so that the material table can be folded. The overall structure of the locking structure is simple and convenient to use.

[0014] Preferably, the elastic member is a torsion spring, and the elastic member is mounted on the rotating shaft of the locking piece.

[0015] Preferably, there are two support rods, and the two support rods are symmetrically mounted on both sides of the fixed rod. One ends of the two support rods away from the fixed rod are respectively fixed to both ends of the sliding rod, and the support rods are located on both sides of the folding rod.

[0016] By adopting the above technical solution, two support rods are symmetrically arranged. When the material table bears pressure, the two support rods can evenly distribute the pressure to both sides of the fixed rod and the folding rod, making the force on the folding rod and the fixed rod more uniform, so that the supporting effect when the material table is opened is more stable.

[0017] Preferably, the fixed rod is made of a profile with a "U" - shaped cross - section, and the opening direction of the fixed rod faces away from the machine body; the end of the folding rod is inserted into the fixed rod and is rotatably connected to the two side walls of the fixed rod.

[0018] By adopting the above technical solution, when folding the material table, the folding rod can be folded and stored in the opening of the fixed rod, so that the material table can be closer to the machine body, thereby further reducing the space occupied when the material table is folded.

[0019] Preferably, there are two sets of folding assemblies, and the two sets of folding assemblies are respectively arranged on both sides under the material table.

[0020] By adopting the above technical solution, the two sets of folding assemblies are arranged on both sides of the material table. When the material table is in use, it will bear the pressure from the film coil, and the folding assemblies can support it from both sides of the material table, effectively improving the stability of the material table during use.

[0021] Preferably, the tabletop of the material table is a downward - concave arc - shaped structure.

[0022] By adopting the above technical solution, the arc - shaped tabletop can prevent the film coil from rolling on the material table.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The material table can be opened or folded to one side of the machine body through the folding assembly. In the process of opening the material table, the material table drives the folding rod to rotate. Since one end of the support rod is rotatably connected to the fixed rod, the other end of the support rod slides on the folding rod during the process of the folding rod rotating and opening. When the material table is rotated to a horizontal position, the position of the support rod on the folding rod is locked by the locking structure, thereby realizing the fixation of the material table in the horizontal direction. When the material table needs to be folded, the locking structure on the sliding end of the support rod is released, and the end of the support rod can slide freely on the folding rod, and then the material table is rotated to make the sliding end of the support rod slide to the end of the folding rod away from the fixed rod, so that the material table is folded to one side of the machine body, thereby effectively reducing the space occupied by the material table, so as to realize flexible use of space and facilitate operation.

[0025] 2. By symmetrically setting two support rods, when the material platform is under pressure, the two support rods can evenly distribute the pressure to both sides of the fixed rod and the folding rod, so that the force of the folding rod and the fixed rod is more uniform, so that the support effect of the material platform when it is opened is more stable;

[0026] 3. By setting the table top as a downwardly concave arc structure, the film roll can be prevented from rolling on the material table, making it convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The embodiment of the present application discloses a loading mechanism of a degreasing stretching oven.

[0035] Reference Figure 1 and Figure 2 A feeding mechanism of a degreasing stretching oven is located at one end of the feeding port of the degreasing stretching oven, and the feeding mechanism is used to feed the film to be processed into the oven box 6. The feeding mechanism includes a machine body 1, a reel 2, a material table 3, a damper 4 and a folding component 5. The reel 2 is rotatably installed above the machine body 1, and the damper 4 is connected to one end of the reel 2 to control the reeling damping of the reel 2; the material table 3 is arranged on the side of the machine body 1 away from the oven box 6, and the material table 3 is connected to the machine body 1 through the folding component 5, and the material table 3 can be folded on one side of the machine body 1 through the folding component 5.

[0036] When in use, the material table 3 is opened, and the film coil to be loaded is placed on the material table 3. When the previous film coil is almost used up, the film on the material table 3 is connected with the film being loaded, and then a new film coil is replaced. After the material table 3 is used up, the material table 3 is folded by the folding component 5 to achieve the effect of saving space and convenient use.

[0037] The material table 3 is a rectangular plate structure. When the material table 3 is opened, the material table 3 is horizontally connected to the end of the machine body 1 away from the oven box 6, and the end of the material table 3 close to the machine body 1 is in contact with the side wall of the end of the machine body 1 away from the oven box 6. A baffle 31 is fixed to the peripheral side of the material table 3. The baffle 31 is arranged along the contour direction of the material table 3. When the material table 3 is opened to a horizontal position, the baffle 31 is located on the upper side of the material table 3, which is used to limit the film coil. The table top of the material table 3 is a circular arc structure that is concave downward. The axis of the circular arc table top is parallel to the axis of the unwinding roller 2. The circular arc table top can prevent the film coil from rolling on the material table 3.

[0038] Reference Figure 1 and Figure 3, the folding assembly 5 includes a folding rod 51, a support rod 52, a fixed rod 53, and a locking structure 54. The fixed rod 53 is vertically fixed on the side wall of the machine body 1. The fixed rod 53 is a profile with a "U" - shaped cross - section, and the opening direction of the fixed rod 53 faces away from the machine body 1. The folding rod 51 is fixed to the bottom of the material table 3 perpendicular to the direction of the unwinding roller 2. The folding rod 51 is a profile with a "U" - shaped cross - section, and the opening direction of the folding rod 51 faces away from the material table 3. The end of the folding rod 51 is inserted into the fixed rod 53, and the side wall of the folding rod 51 is rotatably connected to the side wall of the fixed rod 53. The rotation axis of the folding rod 51 is perpendicular to the length direction of the fixed rod 53, and the folding rod 51 can be folded and stored in the fixed rod 53. One end of the side wall of the folding rod 51 away from the fixed rod 53 is provided with a chute 511, and the length direction of the chute 511 is parallel to the length direction of the folding rod 51. One end of the support rod 52 is rotatably connected to the lower end of the fixed rod 53, and the other end of the support rod 52 is fixed with a sliding rod 521. The sliding rod 521 is slidably installed in the chute 511 along the length direction of the chute 511. The locking structure 54 is arranged at one end of the folding rod 51 close to the chute 511 for limiting the position of the sliding rod 521 in the chute 511.

[0039] When the material table 3 is opened, the material table 3 drives the folding rod 51 to rotate. Since one end of the support rod 52 is rotatably installed on the fixed rod 53, during the process of the folding rod 51 rotating and opening, the sliding rod 521 slides towards one end of the fixed rod 53 in the chute 511. When the sliding rod 521 slides to one end of the chute 511 close to the fixed rod 53, the locking structure 54 limits the position of the sliding rod 521. At this time, the fixed rod 53, the support rod 52, and the folding rod 51 form a right - angled triangle structure, thereby realizing the stable support of the folding assembly 5 for the material table 3.

[0040] There are two support rods 52, and the two support rods 52 are symmetrically installed on both sides of the fixed rod 53. A connecting rod 522 is fixed at one end of the support rod 52 close to the fixed rod 53. The connecting rod 522 is perpendicular to the length direction of the fixed rod 53, and the support rods 52 are respectively located at both ends of the connecting rod 522. The connecting rod 522 penetrates through the two side walls of the fixed rod 53 and is rotatably matched with it. The two ends of the support rods 52 away from the fixed rod 53 are respectively fixed to both ends of the sliding rod 521, and the support rods 52 are located on both sides of the folding rod 51.

[0041] Refer to Figure 3 and Figure 4 , the locking structure 54 includes a lock piece 542 and an elastic member 541. The lock piece 542 is a long strip - shaped plate body. The lock piece 542 is rotatably connected to one end of the folding rod 51 close to the chute 511, and the rotation axis of the lock piece 542 is perpendicular to the two side walls of the folding rod 51. The elastic member 541 is a torsion spring. The elastic member 541 is installed on the rotation axis of the lock piece 542, so that one end of the lock piece 542 close to the fixed rod 53 abuts against the bottom of the folding rod 51.

[0042] Reference Figure 4 and Figure 5 A circular arc groove 543 is formed at one end of the locking piece 542 close to the fixing rod 53, and a locking gap 544 is formed between one end of the locking piece 542 close to the circular arc groove 543 and the side wall of the end of the sliding groove 511. When the sliding rod 521 is located in the locking gap 544, the sliding rod 521 abuts against the groove wall of the circular arc groove 543 to lock the position of the support rod 52.

[0043] When the material table 3 needs to be folded, the locking plate 542 is pressed away from one end of the fixed rod 53, and the locking plate 542 rotates around the rotating shaft to make the sliding rod 521 disengage from the locking gap 544, and then the material table 3 is rotated to be folded. At this time, the sliding rod 521 slides to the other end of the sliding groove 511, so that the material table 3 can be folded and pressed against one side of the machine body 1.

[0044] Reference Figure 3 A side wall of the folding rod 51 near one end of the fixed rod 53 is provided with an avoidance groove 512, and the position of the avoidance groove 512 corresponds to the position of the connecting rod 522. When the material platform 3 is folded, the connecting rod 522 falls into the avoidance groove 512, so that the folding rod 51 can be stored in the fixed rod 53, so that the material platform 3 can be closer to the body 1, thereby further reducing the space occupied by the material platform 3 when it is folded.

[0045] Two groups of folding components 5 are provided, and the two groups of folding components 5 are respectively arranged on both sides below the material platform 3, so that the folding components 5 support and fix the material platform 3 more stably.

[0046] The implementation principle of the embodiment of the present application is: by setting a folding component 5, the material table 3 can be folded and stored on one side of the body 1 through the folding component 5. When the film roll needs to be replaced, the material table 3 is opened through the folding component 5, and then the film roll is placed on the material table 3, which is convenient for replacing the film roll; when the material table 3 is not needed, the material table 3 is folded and stored on one side of the body 1, which can effectively reduce the space occupied by the material table 3, realize flexible use of space, and facilitate operation.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
