Description

Technical Field

[0001] This utility model relates to the technical field of rubber bottle stopper production equipment, and in particular to a waste stripping device for rubber bottle stopper production. Background Technology

[0002] In the production of rubber bottle stoppers, raw rubber sheets are placed in a vulcanizing machine for vulcanization to form semi-finished bottle stoppers. These semi-finished stoppers then undergo a slitting process to separate them into individual stoppers. Currently, slitting is performed using a slitting mold. During slitting, the semi-finished stoppers are placed on a bottom template 20. The upper mold moves downwards under the action of a stamping device, and the lower edge of the stamping cutter at the bottom of the upper mold engages with the upper end of the upper mold hole 21 on the template 20 to cut the stopper from the semi-finished rubber sheet. Afterwards, the upper mold moves upwards under the action of the stamping device. At this point, the waste material from the semi-finished stoppers is still on the template 20, requiring manual removal before new semi-finished stoppers can be placed. To quickly remove the waste material from the template 20 and improve production efficiency, our technical personnel have proposed this utility model for a waste material stripping device in rubber bottle stopper production.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0025] Example 1: See Figure 1 , 4A waste stripping device for rubber bottle stopper production includes a base plate 10 and a template 20. The template 20 is installed on the upper side of the base plate 10 and has several die holes 21. The base plate 10 has a stripping hole 11 located below the die holes 21. A waste stripping nozzle 30 is installed on one side of the template 20. The waste stripping nozzle 30 is elongated and has an air vent 34 on one side of its upper end, facing the die holes 21. An air guide groove 33 is provided inside the waste stripping nozzle 30 and is connected to the air vent 34. An air supply channel 13 is provided on the waste stripping nozzle 30 or the base plate 10 and is connected to the air guide groove 33. By installing a waste stripping nozzle 30 on one side of the template 20, compressed air is injected into the air supply channel 13 when waste needs to be removed. The compressed air is blown out from the air outlet 34, stripping the waste on the template 20 and blowing it to the other side. This eliminates the need for manual removal of waste and improves production efficiency.

[0026] In this embodiment, the waste stripping nozzle 30 is installed on the top surface of the template 20. In one embodiment, the waste stripping nozzle 30 is welded and fixed to the top surface of the template 20. In this way, the air supply channel 13 can be set on the waste stripping nozzle 30, directly supplying compressed air to the air guide groove 33 inside the waste stripping nozzle 30. In another embodiment, the air supply channel 13 can also be set on the base plate 10, and the air supply channel 13 on the base plate 10 communicates with the air guide groove 33 inside the waste stripping nozzle 30.

[0027] Example 2: In this embodiment, see Figure 1-6 A sliding hole 23 is provided on one side of the template 20. A waste stripping nozzle 30 is slidably installed in the sliding hole 23. An air supply channel 13 is provided on the base plate 10 and is connected to the sliding hole 23. When compressed air is introduced into the air supply channel 13, the air outlet 34 of the waste stripping nozzle 30 extends out of the sliding hole 23. With the above structure, when the upper mold needs to be pre-pressed with the template 20, the upper mold and the template 20 need to be in close contact. At this time, the waste stripping nozzle 30 can retract into the sliding hole 23 under the extrusion of the upper mold.

[0028] Specifically, see Figure 3 The sliding hole 23 includes a bottom hole 231 and a top hole 232 located above the bottom hole 231. The width and length of the top hole 232 are both smaller than the width and length of the bottom hole 231. See also Figure 5 , 6 The waste stripping nozzle 30 includes a guide block 31 and an extension block 32 fixed on the upper side of the guide block 31. An air outlet 34 is disposed on the extension block 32. An air guide groove 33 is located inside the guide block 31 and the extension block 32. The guide block 31 is slidably installed in the bottom hole 231. The extension block 32 is located in the top hole 232. The height of the bottom hole 231 is 1.5 to 2 times the height of the guide block 31. The air supply channel 13 is connected to the bottom hole 231.

[0029] Further, see Figure 3 A sealing ring 24 is installed on the step 233 between the bottom hole 231 and the top hole 232. When the waste stripping nozzle 30 moves upward, the waste stripping nozzle 30 and the sealing ring 24 are squeezed together, so that the waste stripping nozzle 30 and the template 20 are better sealed.

[0030] Furthermore, an annular sealing groove 234 is provided on the step 233, and the sealing ring 24 is embedded and fixed in the sealing groove 234.

[0031] Specifically, see Figure 3 The cross-section of the sealing ring 24 is T-shaped.

[0032] The sealing ring 24 and the step 233 can be further bonded and fixed to prevent the sealing ring 24 from falling off.

[0033] See Figure 3 The head end of the air supply channel 13 is provided with an internal thread 14, and the air pipe connector is screwed and fixed to the internal thread 14.

[0034] See Figure 1 The base plate 10 and the template 20 are connected and fixed by screws 40. Specifically, the bottom of the base plate 10 is provided with multiple countersunk bolt holes 12, and the template 20 is provided with multiple threaded holes 22. The threaded end of the screw 40 passes through the countersunk bolt hole 12 and is then screwed into the threaded hole 22 for fixation.

[0035] The working principle or process of the utility model: During use, when the upper mold is in the upper position, compressed air is not supplied to the air supply channel 13. Figure 3 As shown, a semi-finished bottle stopper can be placed on the template 20 at this time. Then, the upper mold moves downwards under the action of the stamping equipment. The lower edge of the stamping cutter at the bottom of the upper mold engages with the upper end of the upper mold hole 21 on the template 20, cutting the bottle stopper off a semi-finished film. Afterwards, the upper mold moves upwards under the action of the stamping equipment. During this upward movement, compressed air is injected into the air supply channel 13. The compressed air is blown out from the air outlet 34, peeling off the waste material on the template 20 and blowing it to the other side. This eliminates the need for manual removal of the waste material, improving production efficiency.

[0036] In practical use, a two-position two-way solenoid valve is installed on the air pipe that supplies air to the air supply channel 13. By controlling the opening of the solenoid valve, compressed air is supplied to the air supply channel 13.

[0037] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
