Detailed implementation mode

[0027] To make the purpose, technical solution and beneficial effects of the present utility model clearer, the implementation mode of the present utility model will be described in further detail below with reference to the accompanying drawings.

[0028] As Figures 1 to 7 shown, the present utility model provides a new type of trimming machine for silicone rubber parts, including a horizontally arranged workbench 8 with a cavity structure. A vertically distributed storage barrel 4 is installed on the tabletop of the workbench 8. The storage barrel 4 is a cylindrical structure with openings at both ends, and a discharge port is provided on the outer side wall of the storage barrel 4. The discharge port is located at the bottom of the storage barrel 4, and an openable and closable discharge gate 9 is installed on the discharge port. Specifically, the workbench 8, the storage barrel 4 and the discharge gate 9 are all prior arts; when the discharge gate 9 is in the closed state, the discharge port can be sealed; a first driving motor 10 coaxial with the storage barrel 4 is installed in the workbench 8. The output shaft of the first driving motor 10 passes through the tabletop of the workbench 8 and is provided with a rectangular tube located in the storage barrel 4. The rectangular tube is coaxial with the storage barrel 4. A disk 2 coaxial with and adapted to the storage barrel 4 is arranged in the storage barrel 4, that is, the disk 2 can rotate in the storage barrel 4; a rectangular block 1 capable of being inserted into the rectangular tube is fixedly connected to the bottom surface of the disk 2, and a stirring mechanism 3 located in the storage barrel 4 and of different structural forms is coaxially installed on the top surface of the disk 2. Specifically, during use, by setting the first driving motor 10, the stirring mechanism 3 can be driven to rotate. In this way, through the friction between the stirring mechanism 3 and the silicone rubber part products in the storage barrel 4, the flash burrs can be easily detached from the silicone rubber part products; by installing the stirring mechanism 3 on the disk 2, and the disk 2 and the output shaft of the first driving motor 10 are inserted into each other through the rectangular block 1 and the rectangular tube, the stirring mechanism 3 can be easily disassembled and assembled in the storage barrel 4; in addition, since the stirring mechanism 3 has different structural forms, during use, the corresponding stirring mechanism 3 can be replaced according to different types of silicone rubber part products to reduce production costs, so as to facilitate trimming different types of silicone rubber part products.

[0029] After trimming is completed, the discharge gate 9 can be opened, and then the trimmed silicone rubber part products and the detached flash burrs can be discharged out through the discharge port. Subsequently, when screening the flash burrs, the separation of the silicone rubber part products and the flash burrs can be realized.

[0030] The specific setting methods of the stirring mechanism 3 with different structural forms are as follows: First, as Figure 3 And Figure 4As shown, the stirring mechanism 3 includes a stirring shaft 31 coaxially arranged with the disk 2. The bottom end of the stirring shaft 31 is connected to the disk 2, and a number of first stirring blades 32 are installed on the stirring shaft 31 from top to bottom, equally spaced along the circumferential direction of the stirring shaft 31. Each first stirring blade 32 is parallel to the radial direction of the storage barrel 4; secondly, as Figure 5 shown, the length of the first stirring blade 32 at the bottom of the stirring shaft 31 is greater than the length of the first stirring blade 32 at the top of the stirring shaft 31; thirdly, as Figure 6 shown, the stirring mechanism 3 includes a number of horizontally arranged second stirring blades 33. The number of second stirring blades 33 is equally spaced along the circumferential direction of the disk 2, and each second stirring blade 33 is connected to the disk 2 through a countersunk head bolt 34, which facilitates the disassembly and assembly of the second stirring blade 33 on the disk 2; by setting the stirring mechanism 3 into different structural forms, it is convenient to trim different types of silicone rubber parts products.

[0031] When trimming the silicone rubber parts products, to prevent the silicone rubber parts products from splashing out from the top opening position of the storage barrel 4, therefore, as Figure 1 and Figure 7 shown, a barrel cover 11 is provided at the top opening position of the storage barrel 4. One side of the barrel cover 11 is hinged to the storage barrel 4, and a first handle 12 is installed on the outer surface of the barrel cover 11. The first handle 12 facilitates the opening and closing of the barrel cover 11; by setting the barrel cover 11, it can be used to close the top opening position of the storage barrel 4, so that during the process of trimming the silicone rubber parts products, the silicone rubber parts products can be prevented from splashing out from the top opening position of the storage barrel 4.

[0032] When trimming the silicone rubber parts products, to prevent the operator from accidentally opening the barrel cover 11, therefore, as Figure 1 and Figure 2As shown in the figure, a locking mechanism 5 for locking the lid 11 is installed on one side of the storage bucket 4. The locking mechanism 5 includes a second driving motor 51 vertically installed on the outer wall of the storage bucket 4. The second driving motor 51 is a forward and reverse motor. A vertically distributed electric telescopic rod 52 is coaxially installed on the output shaft of the second driving motor 51. The electric telescopic rod 52 can be set as a small cylinder, etc. And in the initial state, the telescopic end of the electric telescopic rod 52 is in the extended state. The top end of the electric telescopic rod 52 is the telescopic end and is installed with a horizontally arranged connecting block 53. A locking screw rod 54 vertically penetrating the connecting block 53 is threadedly connected to the connecting block 53. Specifically, when in use, when the lid 11 is in the closed state, the second driving motor 51 can drive the electric telescopic rod 52 to rotate until the bottom end of the locking screw rod 54 is located above the lid 11. Then, when the electric telescopic rod 52 retracts, it can drive the bottom end of the locking screw rod 54 to abut against the lid 11 to lock the lid 11. In this way, during the process of trimming the silicone rubber parts, it can prevent the operator from accidentally opening the lid 11. Secondly, by rotating the locking screw rod 54, it is convenient to adjust the height position of the bottom end of the locking screw rod 54 in the vertical direction, so that it is more convenient for the locking mechanism 5 to lock the lid 11.

[0033] When the lid 11 is in the open state, to prevent the first driving motor 10 from driving the stirring mechanism 3 to rotate. Therefore, as Figure 1 、 Figure 2 and Figure 7 shown, an inductor 13 is installed on one side of the storage bucket 4. The inductor 13 can be set as a proximity sensor, etc. An induction plate 14 opposite to the position of the inductor 13 is fixedly connected to the lid 11. A control cabinet 15 with a control panel is erected on the tabletop of the workbench 8. The control cabinet 15 is electrically connected to the first driving motor 10, the second driving motor 51, the electric telescopic rod 52, and the inductor 13 respectively. Specifically, the control cabinet 15 is a control cabinet in the prior art. When in use, the control cabinet 15 can automatically control the operation of the first driving motor 10, the second driving motor 51, and the electric telescopic rod 52. And the inductor 13 can judge whether the lid 11 is in the closed state by detecting the position of the induction plate 14, that is, only when the lid 11 is in the closed state, when the inductor 13 senses the induction plate 14, the control cabinet 15 can control the first driving motor 10 to start to drive the stirring mechanism 3 to rotate. On the contrary, when the lid 11 is in the open state, that is, when the inductor 13 does not sense the induction plate 14, the first driving motor 10 cannot be started, thereby improving the safety during operation. In addition, a start key, a stop key, a power switch, a regulator for adjusting the rotation speed of the first driving motor 10, and a display for setting and displaying the rotation time of the first driving motor 10, etc. in the prior art are also installed on the control cabinet 15, which is more convenient to use.

[0034] When trimming silicone rubber parts, after the flash burrs are separated from the silicone rubber parts, to facilitate the cleaning of the flash burrs from the storage bin 4 and reduce the workload of subsequent screening of the flash burrs. Therefore, as Figure 1 and Figure 7 shown, an air inlet pipe 7 vertically penetrating the lid 11 is installed on the lid 11 of the bin. During use, one end of the air inlet pipe 7 outside the lid 11 is connected to an air pump; a number of grid holes 41 are provided on the outer side wall of the storage bin 4. The grid holes 41 can be set to be strip-shaped, and the size of each grid hole 41 cannot allow the silicone rubber parts to pass through; a slag collection bag detachably installed on the outer wall of the storage bin 4 is commonly connected among a number of grid holes 41. One end of the slag collection bag close to the storage bin 4 is installed on the storage bin 4 by bolts. Specifically, a number of grid holes 41 are in a group, and multiple groups of grid holes can be provided along the circumferential direction of the storage bin 4; during use, when the stirring mechanism 3 is stirring the silicone rubber parts, the air pump can be started. In this way, through the air inlet pipe 7, the separated flash burrs can be blown into the slag collection bag through the grid holes 41, so as to facilitate the cleaning of the flash burrs from the storage bin 4; secondly, when it is necessary to clean the flash burrs in the slag collection bag, since the slag collection bag is detachably installed on the storage bin 4, the slag collection bag can be removed for cleaning; or the end of the slag collection bag far from the storage bin 4 can be opened, and the opening can be sealed with a binding band. In this way, when cleaning the flash burrs in the slag collection bag, only the end of the slag collection bag far from the storage bin 4 needs to be opened.

[0035] The specific setting method for the discharge gate 9 to be openable and closable is as follows: as Figure 1 and Figure 7 shown, a discharge pipe 16 which is obliquely distributed and located above the workbench 8 is fixedly connected to the discharge port. The higher end of the discharge pipe 16 is connected to the discharge port, and an observation port is provided on the side of the discharge pipe 16 far from the workbench 8. An observation cover 17 which is openable and closable and used to seal the observation port is installed on the observation port. Specifically, one side of the observation cover 17 is hinged to the discharge pipe 16, and a second handle 18 is installed on the observation cover 17. The second handle 18 can facilitate the opening and closing of the observation cover 17; the discharge gate 9 is vertically distributed, and the discharge gate 9 is located at one end of the discharge pipe 16 close to the storage bin 4 and is inserted into the discharge pipe 16. Specifically, a third handle 19 is installed on the discharge gate 9. The third handle 19 can facilitate the lifting and lowering of the discharge gate 9, so as to facilitate the opening and closing of the discharge gate 9. When the discharge gate 9 is in the open state, the trimmed silicone rubber parts and the fallen flash burrs can be discharged through the discharge pipe 16; in addition, when the observation cover 17 is opened, it is convenient to observe the discharging situation in the discharge pipe 16.

[0036] To facilitate the movement of the position of the present utility model, therefore, as Figure 1 and Figure 7As shown, two symmetrically arranged inverted U-shaped handles 20 are installed on both sides of the tabletop of the workbench 8. By setting the inverted U-shaped handles 20, it is convenient to carry and move this utility model; in addition, leveling legs 6 that can adjust the height position vertically are installed at the four corners of the bottom surface of the workbench 8. Specifically, each leveling leg 6 includes a horizontally arranged support 61, and a vertically distributed leg 62 is installed on each support 61. Each leg 62 is a threaded rod, and each leg 62 is threadedly connected to the workbench 8 through a threaded hole vertically opened on the bottom surface of the workbench 8. During use, by rotating the leg 62, the height position of the support 61 can be adjusted. In this way, after moving this utility model in place, the position of the workbench 8 can be leveled according to requirements; in addition, a locking nut 63 is threadedly connected to each leg 62 between the support 61 and the workbench 8. In this way, after adjusting the height position of the support 61, by rotating the locking nut 63, the locking nut 63 can be tightened against the bottom surface of the workbench 8 to further fix the position of the support 61.

[0037] Furthermore, the use process of this utility model is as follows: In the initial state, the bucket cover 11 is in the open state, and the feeding gate 9 is in the closed state; before use, the corresponding stirring mechanism 3 can be replaced according to different types of silicone rubber parts products; during use, first, pour the silicone rubber parts products to be trimmed into the storage bucket 4, and then close the bucket cover 11. At this time, the locking mechanism 5 can be automatically controlled by the control cabinet 15 to lock the bucket cover 11, and at the same time, start the first driving motor 10 to drive the stirring mechanism 3 to rotate. Then start the air pump, and the separated flash burrs can be blown into the slag collection bag through the air inlet pipe 7. Then, when the trimming is completed, open the feeding gate 9, and the silicone rubber parts products and the flash burrs that have not been blown away can be discharged through the discharge pipe 16.
