Description

Technical Field

[0001] This utility model relates to the technical field of positioning fixtures for toothbrush handles, and in particular to a pad printing positioning fixture for toothbrush handles. Background Technology

[0002] Toothbrush handle positioning fixtures are key devices used to precisely fix the position of toothbrush handles during the pad printing process.

[0003] Existing positioning fixtures have the following shortcomings when in use:

[0004] The existing positioning fixture uses an internal anti-form positioning clamp. In actual production, the handle is often not inserted into the internal anti-form properly, which leads to misalignment of the printed product and reduces the yield rate. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that existing positioning fixtures use internal anti-shaping positioning jigs, which in actual production are prone to situations where the handle is not inserted into the internal anti-shaping, resulting in product printing misalignment and reducing the yield rate. Therefore, this utility model proposes a pad printing positioning fixture for toothbrush handle products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pad printing positioning fixture for toothbrush handles includes a base, with anti-conformity limiting blocks fixed to the top of the base by bolts. Two external anti-conformity positioning blocks for the handles are fixedly installed on the top of the base, and toothbrush handles are placed on the two external anti-conformity positioning blocks. A positioning mechanism is provided on the top of the base, which can position the toothbrush handles when positioning is required.

[0008] In one possible design, the positioning mechanism includes a cylinder, a bracket, and a second anti-conformity positioning block. The bottom of the cylinder is fixedly connected to one side of the top of the base. The bracket is U-shaped, and one side of the bracket is fixedly connected to the telescopic part of the cylinder. One side of the second anti-conformity positioning block is fixedly connected to one side of the bracket, and one end of the second anti-conformity positioning block is inserted into the toothbrush handle.

[0009] In one possible design, a blocking groove is provided on the top side of the base to prevent the toothbrush handle from moving when the second anti-shaping positioning block retracts, and the bottom of one end of the toothbrush handle abuts against the blocking groove.

[0010] In one possible design, a guide rail for improving the stability of the support movement is fixedly mounted on the top of the base, and a slider for cooperation is slidably connected to the top of the guide rail, with the top of the slider fixedly connected to the bottom of the support.

[0011] In one possible design, both sides of the second anti-deformation positioning block are provided with guide positioning grooves that are adapted to the internal shape of the toothbrush handle.

[0012] In one possible design, the outer anti-conformity positioning block of the handle is made of Teflon, and the shape of the middle part of the outer anti-conformity positioning block is adapted to the shape of the toothbrush handle.

[0013] In this application, during use, the toothbrush handle is manually placed onto the two external anti-conformity positioning blocks, with one end of the toothbrush handle aligned with one side of the anti-conformity limiting block. Then, the cylinder is activated, causing its telescopic part to extend and retract. This extension and retraction moves the bracket and the second anti-conformity positioning block, allowing the second anti-conformity positioning block to insert into the toothbrush handle. This positions and tightens the toothbrush handle. During the insertion of the second anti-conformity positioning block, the guide and alignment groove guides and aligns the insertion, ensuring accurate insertion and precise positioning of the toothbrush handle. (If the product is slightly misaligned during manual placement, the second anti-conformity positioning block will not insert into the toothbrush handle; this design allows for secondary correction, ensuring accurate positioning.) After positioning is complete... An external pad printing machine prints on the toothbrush handle. Then, the cylinder retracts, causing the second anti-shaping positioning block to leave the toothbrush handle. As the second anti-shaping positioning block retracts, the tail of the handle slightly engages with the blocking limit groove, creating resistance. This prevents the toothbrush handle from retracting along with the product, significantly reducing defects. This application can complete the most complex positioning action at the lowest cost. Based on the requirement for precision, it incorporates multiple designs to achieve the superposition of positioning accuracy for products that cannot be positioned externally. It also designs a secondary calibration action. These calibration mechanisms do not require additional mechanisms; they are all extensions of necessary actions. Furthermore, an innovative material ejection blocking design eliminates the risk of the product being pulled out by the user during ejection. It should be noted that the cylinder requires an external air source, power supply, and controller for operation.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this utility model, the toothbrush handle product pad printing positioning fixture achieves precise positioning of the toothbrush handle by setting a dual positioning structure of an external anti-deformation positioning block and a second anti-deformation positioning block. The external anti-deformation positioning block can initially fix the position of the toothbrush handle, while the second anti-deformation positioning block is inserted into the toothbrush handle for further positioning. The combination of the two greatly improves the positioning accuracy.

[0016] In this utility model, the toothbrush handle product pad printing positioning fixture, through the guide and alignment grooves opened on both sides of the second anti-shaping positioning block, can play a guiding and alignment role during the insertion process, ensuring that the second anti-shaping positioning block can be accurately inserted into the toothbrush handle, avoiding the printing misalignment problem caused by incomplete insertion, thereby improving the product yield.

[0017] In this invention, the toothbrush handle is precisely positioned by a dual positioning structure consisting of an external anti-deformation positioning block and a positioning mechanism. The external anti-deformation positioning block initially fixes the position of the toothbrush handle, while the second anti-deformation positioning block is inserted into the toothbrush handle for further positioning. The combination of the two greatly improves the accuracy of positioning. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figure 1-4A positioning fixture includes a base 10, an anti-conformity limiting block 1, an external anti-conformity positioning block 2 for the handle, a positioning mechanism, a blocking and limiting groove 11, a guide rail 5, and a slider 7. These components work together to precisely position the toothbrush handle 3 for transfer printing. The base 10, as the basic support structure of the entire fixture, is made of sturdy and durable materials to ensure stability during use. The anti-conformity limiting block 1 is bolted to the top of the base 10. During installation, the anti-conformity limiting block 1 is first placed in a preset position on the top of the base 10, and then bolts are used to tightly connect the anti-conformity limiting block 1 to the base 10, ensuring accurate positioning and secure fixation.

[0026] The outer anti-conformity positioning block 2 of the handle is made of Teflon, which has a low coefficient of friction and good wear resistance, effectively reducing wear on the surface of the toothbrush handle 3. The central shape of the outer anti-conformity positioning block 2 is adapted to the shape of the toothbrush handle 3 to achieve initial positioning of the toothbrush handle 3. Two outer anti-conformity positioning blocks 2 are fixedly installed on the top of the base 10. During installation, the outer anti-conformity positioning blocks 2 are placed in the corresponding positions on the top of the base 10, and are firmly fixed to the base 10 by welding, bonding or other suitable fixing methods.

[0027] The positioning mechanism includes a cylinder 6, a bracket 9, and a second anti-deformation positioning block 4. The bottom of the cylinder 6 is fixedly connected to the top side of the base 10. During installation, the cylinder 6 is placed at the designated position on the top of the base 10, and the cylinder 6 is tightly fixed to the base 10 using bolts or other fasteners to ensure that the cylinder 6 does not shake or shift during operation.

[0028] The bracket 9 is U-shaped, and one side of the bracket 9 is fixedly connected to the telescopic part of the cylinder 6. Align one side of the bracket 9 with the telescopic part of the cylinder 6, and use welding, bolts or other methods to firmly connect the bracket 9 and the telescopic part of the cylinder 6 so that the telescopic part of the cylinder 6 can drive the bracket 9 to move.

[0029] One side of the second anti-conformity positioning block 4 is fixedly connected to one side of the bracket 9. During installation, the second anti-conformity positioning block 4 is placed in a suitable position on one side of the bracket 9, and bolts or other fixing methods are used to ensure that the second anti-conformity positioning block 4 is tightly connected to the bracket 9, ensuring that the second anti-conformity positioning block 4 can move with the bracket 9. One end of the second anti-conformity positioning block 4 is designed to be inserted into the toothbrush handle 3 to achieve further positioning of the toothbrush handle 3.

[0030] This application is for positioning fixtures for toothbrush handles, but can also be used in other fields applicable to this application.

[0031] Example 2

[0032] refer to Figure 1-4 An improvement based on Embodiment 1: A pad printing positioning fixture for toothbrush handle products, which is used in the field of positioning fixtures for toothbrush handle products.

[0033] A blocking and limiting groove 11 is provided on one side of the top of the base 10. The function of the blocking and limiting groove 11 is to prevent the toothbrush handle 3 from moving when the second anti-shaping positioning block 4 retracts. When the toothbrush handle 3 is placed on the fixture, the bottom of one end of the toothbrush handle 3 abuts against the blocking and limiting groove 11, thereby playing a blocking role.

[0034] A guide rail 5 is fixedly mounted on the top of the base 10, and a matching slider 7 is slidably connected to the top of the guide rail 5. The top of the slider 7 is fixedly connected to the bottom of the bracket 9. When installing the guide rail 5, place it at a preset position on the top of the base 10 and securely fix it to the base 10 using bolts or other fixing methods. Then, install the slider 7 on the guide rail 5, ensuring that the slider 7 can slide smoothly on the guide rail 5. Finally, fix the bottom of the bracket 9 to the top of the slider 7, using welding, bolting, or other methods to ensure a tight connection between the bracket 9 and the slider 7. Thus, when the cylinder 6 moves the bracket 9, the slider 7 will slide along the guide rail 5, thereby improving the stability of the bracket 9's movement.

[0035] Guide and alignment grooves 8, adapted to the internal shape of the toothbrush handle 3, are formed on both sides of the second anti-formation positioning block 4. During the machining of the second anti-formation positioning block 4, milling machines, wire cutting machines, and other machining equipment are used to precisely form the guide and alignment grooves 8 on both sides of the second anti-formation positioning block 4 according to design requirements, ensuring that the shape and size of the guide and alignment grooves 8 match the internal shape of the toothbrush handle 3. The guide and alignment grooves 8 play a guiding and alignment role during the insertion of the second anti-formation positioning block 4 into the toothbrush handle 3, ensuring that the second anti-formation positioning block 4 can be accurately inserted into the toothbrush handle 3, thus improving positioning accuracy.

[0036] However, as is well known to those skilled in the art, the working principle and wiring method of cylinder 6 are commonplace and are all conventional methods or common knowledge, so they will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0037] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
