This printing process can make plastic products more beautiful and increase their market appeal. The fixing device of the plastic product surface printing machine is an auxiliary device used to fix and stabilize the plastic products to be printed during the printing process.

[0003] Existing printing machines typically use several positioning blocks to achieve a resistive and limiting effect when positioning plastic products. This requires manual adjustment of the plastic products to be centered. Furthermore, the existing positioning blocks are generally set in fixed positions, which cannot adapt to the positioning needs of plastic products of various sizes. Overall usability needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned problems by proposing a fixing device for a plastic product surface printing machine. It improves the existing printing machine, which generally uses several positioning blocks to achieve the effect of resisting and limiting when positioning plastic products. It requires manual adjustment of the plastic products to be centered. Moreover, the existing positioning blocks are generally set in fixed positions, which cannot adapt to the positioning needs of plastic products of various sizes. The overall adaptability needs to be improved.

[0005] A fixing device for a plastic product surface printing machine includes a placement base, a positioning baffle, an abutment limiting mechanism, a spacing adjustment mechanism, and a positioning assembly mechanism: the positioning baffle is fixedly installed on the top outer wall of the placement base;

[0006] The abutment limiting mechanism includes a strip support base, a piston cylinder, a piston rod, and an abutment spring. Two sets of strip support bases are slidably installed opposite each other on the top outer wall of the placement base. Piston cylinders are embedded in the side outer walls of the strip support bases at equal intervals. A piston rod is slidably installed inside the piston cylinder, and an abutment spring is connected between the piston rod and the bottom inner wall of the piston cylinder.

[0007] Preferably, the protruding end of the piston rod is located on the outside of the piston cylinder and connected to the side outer wall of the contact frame, and a friction pad is embedded in the side outer wall of the contact frame away from the piston rod.

[0008] Preferably, the contact frame is configured in the shape of a "U", and the top outer wall of the contact frame is chamfered.

[0009] Preferably, the spacing adjustment mechanism includes a limiting T-block, a limiting T-groove, and a positioning ear plate. The bottom outer wall of the strip support is symmetrically provided with limiting T-blocks, the top outer wall of the placement base is correspondingly provided with a limiting T-groove for sliding installation of the limiting T-blocks, and the side outer wall of the placement base at the bottom position is provided with a positioning ear plate.

[0010] Preferably, the top outer wall of the positioning ear plate is provided with a first threaded groove, and the top outer wall of the placement base is provided with a second threaded groove at equal intervals. The first and second threaded grooves are threadedly installed with the fastening bolts, and scales are symmetrically installed on the side outer wall of the placement base.

[0011] Preferably, the positioning assembly mechanism includes an auxiliary mounting plate and a reinforcing support base.

[0012] Preferably, the reinforcing support is configured as a triangular plate structure, and the top outer wall of the auxiliary mounting plate is provided with two sets of cylindrical through grooves for installing the entire device.

[0013] The beneficial effects of this utility model are:

[0014] 1. When in use, the fixing device of this plastic product surface printing machine uses two sets of spring support components symmetrically arranged. By utilizing the characteristic that springs generate a reaction force synchronously when compressed, the two sets of spring support components can stably position the plastic product to be printed inside the device. This provides a basic guarantee for the accuracy of the subsequent printing position while ensuring the stable and centered positioning of the plastic product. Furthermore, the strip support base is designed to be adjustable through the mechanism components, so that the device can be adjusted to a suitable positioning distance according to the actual size of the plastic product. The overall structure is ingeniously designed and has good adaptability.

[0015] 2. When using this plastic product surface printing machine fixing device, the design of setting friction pads on the side of the elastic support component allows the friction pads to abut against the outer wall of the plastic product. This design increases the contact friction between the device and the outer wall of the plastic product, making the device more stable in positioning the plastic product inside the device.

[0022] 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.

[0023] In practical implementation: such as Figure 1-5 As shown, a fixing device for a plastic product surface printing machine includes a placement base 1, a positioning baffle 2, an abutment limiting mechanism 3, a spacing adjustment mechanism 4, and a positioning assembly mechanism 5: the positioning baffle 2 is fixedly installed on the top outer wall of the placement base 1.

[0024] The contact limiting mechanism 3 includes a strip support base 31, a piston cylinder 32, a piston rod 33, and a contact spring 34. Two sets of strip support bases 31 are slidably installed on the top outer wall of the base 1. The piston cylinders 32 are embedded in the side outer walls of the strip support bases 31 at equal intervals. The piston rod 33 is slidably installed inside the piston cylinder 32. A contact spring 34 is connected between the piston rod 33 and the bottom inner wall of the piston cylinder 32. The protruding end of the piston rod 33 is located on the outside of the piston cylinder 32 and is connected to the side outer wall of the contact frame 35. A friction pad 36 is embedded in the side outer wall of the contact frame 35 away from the piston rod 33.

[0025] When a square plastic product to be printed needs to be placed inside the device for centering, simply push the square plastic product vertically to the middle position of the two sets of contact frames 35. At this time, the contact frames 35 will automatically move to both sides under the pressure of the square plastic product, providing a certain space for the square plastic product. The friction pad 36 here increases the contact friction between the device and the outer wall of the square plastic product, so that the device can better position the square plastic product inside the device. When the contact frames 35 move, they will also automatically drive the piston rod 33 to slide inside the piston cylinder 32. At this time, the contact spring 34 will deform and contract under the pressure of the piston rod 33. At the same time, the contact spring 34 will generate a reaction force under the pressure and push the piston rod 33 to move in the opposite direction and push the contact frame 35 to make tight contact with the side outer wall of the square plastic product. In this process, the square plastic product can be stably positioned inside the device. After printing, it can be taken out directly.

[0026] The contact frame 35 is set in the shape of a "7", and the outer wall of the top of the contact frame 35 is chamfered. Setting the contact frame 35 in the shape of a "7" allows it to be positioned and supported by sliding above the strip support base 31 during movement. The chamfered design on the outer wall of the top of the contact frame 35 makes it easier to push square plastic products to the middle position of the two sets of contact frames 35.

[0027] The spacing adjustment mechanism 4 includes a limiting T-block 41, a limiting T-groove 42, and a positioning ear plate 43. The bottom outer wall of the strip support base 31 is symmetrically provided with limiting T-blocks 41. The top outer wall of the placement base 1 is correspondingly provided with limiting T-grooves 42 for sliding installation of the limiting T-blocks 41. The side outer wall of the placement base 1 at the bottom position is provided with a positioning ear plate 43. The top outer wall of the positioning ear plate 43 is provided with a first threaded groove 44. The top outer wall of the placement base 1 is provided with second threaded grooves 45 at equal intervals. The first threaded groove 44 and the second threaded groove 45 are threadedly installed with the fastening bolt 46. The side outer wall of the placement base 1 is symmetrically provided with a scale 47.

[0028] When the installation spacing of the two sets of strip support seats 31 needs to be adjusted according to the width of the square plastic product, the scale 47 here provides a distance reference for the subsequent movement of the strip support seats 31. When the installation position of the strip support seat 31 needs to be adjusted, the fastening bolt 46 needs to be unscrewed from the inside of the first threaded groove 44, and then the positioning ear plate 43 changes from the locked state to the movable state. Then, the strip support seat 31 is pulled directly to move it to the designated installation position. When the strip support seat 31 moves, it will also automatically drive the limiting T-block 41 to slide inside the limiting T-groove 42. The setting of the limiting T-block 41 and the limiting T-groove 42 here also has the effect of limiting the trajectory of the movement of the strip support seat 31. Then, the fastening bolt 46 is directly passed through the first threaded groove 44 and screwed into the corresponding position of the second threaded groove 45 to complete the relocking of the strip support seat 31.

[0029] The positioning assembly mechanism 5 includes an auxiliary mounting plate 51 and a reinforcing support base 52. The auxiliary mounting plates 51 are symmetrically arranged on the outer walls of the two sides of the base 1 at the bottom position. The reinforcing support base 52 is connected and installed between the top outer wall of the auxiliary mounting plate 51 and the side outer wall of the base 1. The reinforcing support base 52 is set as a triangular plate structure. The top outer wall of the auxiliary mounting plate 51 is provided with two sets of cylindrical through grooves for installing the whole device.

[0030] The cylindrical through slot above the auxiliary mounting plate 51 facilitates the overall positioning and installation of the device at the product placement position on the printing machine, while the triangular structure reinforcement support base 52 above the auxiliary mounting plate 51 utilizes the stability property of triangles to make the device more stable after installation.

[0031] When using this utility model, the device first needs to be positioned and installed at the product placement position of the printing machine through the cylindrical through groove above the auxiliary mounting plate 51.

[0032] Then, adjust the installation spacing of the two sets of strip support seats 31 according to the width of the square plastic product. Here, the scale 47 provides a distance reference for the subsequent movement of the strip support seats 31. When adjusting the installation position of the strip support seats 31, firstly, the fastening bolt 46 needs to be unscrewed from the inside of the first threaded groove 44, and then the positioning ear plate 43 changes from the locked state to the movable state. Then, directly pull the strip support seat 31 to move it to the designated installation position. When the strip support seat 31 moves, it will also automatically drive the limiting T-block 41 to slide inside the limiting T-groove 42. Here, the setting of the limiting T-block 41 and the limiting T-groove 42 also has the effect of limiting the trajectory of the movement of the strip support seat 31. Then, directly pass the fastening bolt 46 through the first threaded groove 44 and screw it into the corresponding position of the second threaded groove 45 to complete the relocking of the strip support seat 31.

[0033] During printing, the square plastic product to be printed needs to be placed inside the device and centered. At this time, simply push the square plastic product vertically to the middle position of the two sets of contact frames 35. The contact frames 35 will automatically move to both sides under the pressure of the square plastic product, providing a certain space for the square plastic product. The friction pad 36 here increases the contact friction between the device and the outer wall of the square plastic product, so that the device can better position the square plastic product inside the device. When the contact frame 35 moves, it will also automatically drive the piston rod 33 to slide inside the piston cylinder 32. At this time, the contact spring 34 is deformed and contracted under the pressure of the piston rod 33. At the same time, the contact spring 34 generates a reaction force under the pressure and pushes the piston rod 33 to move in the opposite direction and push the contact frame 35 to make tight contact with the side outer wall of the square plastic product. In this process, the square plastic product can be stably positioned inside the device. After printing, it can be taken out directly.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
