Description

Technical Field

[0001] The present utility model relates to the technical field of transfer printing machines, in particular to an anti-offset heat transfer printing machine for cosmetic bottles. Background Art

[0002] At present, in the process of decorating the outer surface of cylindrical containers such as cosmetic bottles, heat transfer printing is generally used to transfer patterns or characters to the surface of the bottle body. Traditional heat transfer printing equipment usually consists of a base, a pressing block and a heat transfer film conveying assembly, and pattern transfer is completed through unilateral pressing in cooperation with rolling support under the bottle body.

[0003] In a typical prior art, a cosmetic bottle is placed in a roller groove of a bearing seat, the pressing block carries the heat transfer film to press downward, so that the film contacts the surface of the bottle body, and pattern transfer is realized by means of the rotation of the bottle body on the bearing seat. Although this type of structure can complete basic transfer processing, it has the following deficiencies: Since most traditional devices rely on the unilateral pressing block for downward pressing, the bottle body is only limited and supported on the lower bearing roller, and lacks upper and lower clamping cooperation. During the transfer process, the bottle body is prone to position offset or shaking due to uneven force or changes in frictional resistance, which results in pattern misalignment, blurring or deformation, and affects the aesthetic appearance and processing accuracy of the finished product.

[0004] Existing devices usually control the conveying of the pressing block and the heat transfer film manually, or drive the movement of the film through a simple motor, and fail to realize linkage control with the actual pressed and fitted state of the bottle body. When the bottle body is not accurately positioned or not sufficiently fitted, the heat transfer process may still be started, leading to waste of film and increase in product defect rate.

[0005] In some improved structures, although an electric heating assembly and a winding transmission mechanism are provided, they fail to combine the pressure detection of the bottle body for coordinated control, and the situation that the transfer film is conveyed in advance or the heating is started too early may still occur, which reduces the processing consistency and stability.

[0006] In summary, in the prior art, there are generally problems of unstable pressure support and easy offset of the bottle body, and lack of detection linkage for heat transfer control. These deficiencies not only lead to decreased transfer accuracy and low finished product rate, but also increase operational complexity and energy consumption, which can hardly meet the actual requirements of high precision, stability and automation for cosmetic bottle appearance decoration. Contents of Utility Model

[0007] The present utility model aims to solve one of the technical problems existing in the prior art or related art.

[0008] Therefore, the technical solution adopted by this utility model is as follows: a cosmetic bottle anti-deviation heat transfer machine, including a base, a frame, a pressure rod, a support, and a heat transfer assembly. The support is disposed above the base, and a set of support rollers is rotatably mounted on its surface to support the cosmetic bottle and allow it to rotate during the heat transfer process. The heat transfer assembly includes a pressure block and a positioning block. The pressure block is fixedly connected to the bottom end of the pressure rod, enabling it to press the positioning block against the surface of the cosmetic bottle. The positioning block is movably connected to the pressure block via an elastic guide rod and is monitored by a microswitch during the pressing process, achieving deviation detection and linkage control. Through the above structural design, the upper and lower clamping of the bottle, deviation prevention, and automated linkage heat transfer are achieved.

[0009] In a preferred example, a set of support rollers is rotatably mounted on the surface of the support, with multiple support rollers forming a limiting groove. The cosmetic bottle can be stably placed within the limiting groove. During the transfer process, the support rollers cooperate with the bottle's rotation to achieve continuous pattern transfer on the outer wall of the bottle. Specifically, this structure can prevent the bottle from rolling and misaligning during transfer, improving support stability.

[0010] In a preferred example, the positioning patch has elastic guide rods at the four corners of its top surface, which are movably connected to the bottom surface of the pressure block. This allows the positioning patch to float vertically when the pressure block is pressed down, preventing uneven force distribution caused by uneven bottle surfaces. Specifically, this structure achieves uniform pressure distribution through elastic buffering, thereby improving the consistency of the transfer effect.

[0011] In a preferred example, the surface of the pressure block is provided with an unwinding roller and a rewinding roller. The unwinding roller is used to release the heat transfer film, and the rewinding roller is used to rewind the waste film. Specifically, this structure allows the heat transfer film to be continuously conveyed during the rotation of the bottle, ensuring the efficiency and stability of the transfer process.

[0012] In a preferred example, the bottom surface of the positioning patch has an arc-shaped groove for close contact with the outer curved surface of the bottle. An electric heating component is embedded inside the positioning patch. During operation, the electric heating component heats the heat transfer film, firmly transferring the pattern on the film to the bottle surface. Specifically, this structure improves the adhesion between the film and the bottle, as well as the transfer adhesion, preventing blurring or peeling of the transfer.

[0013] In a preferred example, a microswitch mounted on the bottom of the pressure block is electrically connected to a control circuit. The output of the control circuit is connected to the drive end of the take-up roller and the electric heating assembly, respectively. When the microswitch detects that the positioning patch is fully aligned with the bottle, the control circuit triggers the drive end of the take-up roller and the electric heating assembly to operate, ensuring that heat transfer only occurs when the bottle is stably positioned. Specifically, this structure achieves automatic linkage control, avoiding misoperation when the bottle is not aligned, and improving the intelligence and reliability of the equipment.

[0014] In a preferred embodiment, the frame is equipped with a vertical sliding guide rail, through which the pressure rod moves up and down, driving the pressure block to achieve lifting and lowering motion. A rack is provided on the surface of the pressure rod, and a motor unit and manual throttle are mounted on the frame surface to mesh with the rack, enabling automatic lifting and lowering of the pressure rod or manual operation. Specifically, this structure improves the operational flexibility and applicability of the equipment, meeting both the needs of automated production and allowing for manual operation during power outages or maintenance.

[0015] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, the bearing roller group of the bearing seat and the positioning block of the pressure block form an upper and lower clamping cooperation, and synchronous rotation is achieved under the motor group or manual drive, so that the cosmetic bottle can be stably pressed and maintain axial rotation during the heat transfer process, avoiding the problem of bottle body offset or shaking under the traditional single-sided pressing method, thereby effectively improving the accuracy and stability of heat transfer.

[0016] 2. In this utility model, by setting a micro switch at the bottom of the pressure block and combining it with the control circuit to control the winding wheel, the bearing roller group and the electric heating component, the heat transfer film conveying and heating transfer process is started only when the positioning patch is precisely attached to the surface of the cosmetic bottle. This avoids transfer failure caused by misalignment or offset of the bottle, and improves the automation level and reliability of the equipment. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0020] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0021] The following describes, with reference to the accompanying drawings, some embodiments of a cosmetic bottle anti-deviation heat transfer machine.

[0022] Combination Figures 1-5 As shown, the present invention provides a cosmetic bottle anti-displacement heat transfer machine, including a base 100, a frame 110, a pressure rod 120, a support 200, and a heat transfer assembly 300.

[0023] The support 200 is disposed above the base 100. A roller assembly 210 is rotatably mounted on the surface of the support 200. The roller assembly 210 is used to provide circumferential limiting support for the cosmetic bottle and to drive the cosmetic bottle to rotate during the heat transfer process. The heat transfer assembly 300 includes a pressure block 310 and a positioning block 320. The pressure block 310 is fixedly connected to the bottom end of the pressure rod 120 and is located directly above the support 200. It can press the cosmetic bottle on the support 200 vertically under the action of the pressure rod 120.

[0024] The positioning patch 320 is located below the pressure block 310. Elastic guide rods 321 are provided at the four corners of the top surface of the positioning patch 320, and are movably connected to the bottom surface of the pressure block 310 via the elastic guide rods 321. A micro switch 322 is installed on the bottom surface of the pressure block 310 to monitor the movement state of the positioning patch 320 when the cosmetic bottle is pressed and adhered, thereby achieving position detection and offset control.

[0025] In this embodiment, on the surface of the support 200, the support roller group 210 is composed of multiple rotatably mounted support rollers, and a limiting groove is formed between adjacent support rollers. The cosmetic bottle can be stably placed in the limiting groove. During the transfer process, it can achieve self-rotation or passive rotation while maintaining the limiting position, so as to avoid the bottle body rolling and deviating.

[0026] In this embodiment, the elastic guide rod 321 is arranged perpendicularly to the surface of the pressure block 310, and can guide the positioning patch 320 to perform elastic lifting and lowering movements when the pressure block 310 is pressed down. Through the buffering effect of the elastic guide rod 321, the positioning patch 320 can apply uniform bonding pressure to the cosmetic bottle, thereby avoiding poor pattern transfer caused by uneven local force.

[0027] In this embodiment, an unwinding roller 311 and a winding roller 312 are respectively provided at both ends of the surface of the pressing block 310. The unwinding roller 311 is used to release the heat transfer film, and the winding roller 312 is used to wind up the used heat transfer waste. The heat transfer film is conveyed along the outer wall of the bottle when the pressing block 310 moves, completing the pattern transfer.

[0028] In this embodiment, the bottom surface of the positioning patch 320 is provided with an arc-shaped groove for fitting with the outer curved surface of the cosmetic bottle. An electric heating component is embedded inside the positioning patch 320. When in operation, the electric heating component heats the heat transfer film, so that the pattern or text on the heat transfer film can be firmly transferred to the surface of the bottle.

[0029] In this embodiment, the micro switch 322 is electrically connected to the control circuit, and the output of the control circuit is simultaneously electrically connected to the drive end of the take-up roller 312 and the electric heating assembly. When the micro switch 322 detects that the positioning patch 320 is fully attached to the surface of the cosmetic bottle, the control circuit outputs a control signal, causing the take-up roller 312 to start and pull the heat transfer film for transmission, while the electric heating assembly heats up, achieving synchronous transfer. This linkage control avoids malfunctions when the bottle is not aligned, improving the reliability of the transfer.

[0030] In this embodiment, a vertical sliding guide rail is provided on the inner side of the frame 110. The pressure rod 120 moves up and down along the sliding guide rail, thereby driving the pressure block 310 to complete the pressing and lifting actions. The surface of the pressure rod 120 is provided with a rack structure, and a motor unit and a manual throttle are mounted on the surface of the frame 110 that mesh with the rack. The motor unit can drive the pressure rod 120 to achieve automatic lifting and lowering, while the manual throttle is used for auxiliary operation in non-electric state, thereby improving the flexibility and applicability of the device.

[0031] Working principle and usage process of this utility model: This utility model of a cosmetic bottle anti-deviation heat transfer machine mainly achieves stable support, precise positioning, and deviation prevention of the cosmetic bottle during the heat transfer process through the cooperation of the support 200, the heat transfer component 300, and the positioning detection mechanism. Its working principle is as follows: The cosmetic bottle is placed on the roller assembly 210 of the support 200. The limiting groove formed between the multiple rollers provides circumferential limiting support for the cosmetic bottle and ensures its stability and rotatability during the transfer process. The pressure rod 120 moves vertically along the sliding guide rail under the drive of the motor or manual throttle, thereby driving the pressure block 310 to press down. The surface of the pressure block 310 is provided with an unwinding roller 311 and a winding roller 312. The unwinding roller 311 releases the heat transfer film, and the winding roller 312 collects the waste film, forming a continuous conveying channel for the heat transfer film.

[0032] When the pressure block 310 is pressed down, the positioning patch 320 adheres to the surface of the cosmetic bottle under the guidance of the elastic guide rod 321. The bottom surface of the positioning patch 320 has an arc-shaped groove, which can fit tightly against the outer curved surface of the bottle. The electric heating component embedded inside heats the heat transfer film, so that the pattern or text on the transfer film is transferred to the surface of the bottle.

[0033] A micro switch 322 is provided at the bottom of the pressure block 310. This switch is activated and outputs a detection signal when the positioning block 320 is pressed. After receiving the signal, the control circuit controls the winding wheel 312 to rotate and guide the heat transfer film, and controls the bearing roller group 210 to rotate in the opposite direction, so as to realize the rotation and transfer of the cosmetic bottle. Simultaneously, the upper and lower surfaces of the cosmetic bottle are clamped, rotated and guided, and transferred, thereby realizing heat transfer without displacement of the cosmetic bottle. This ensures that heat transfer is only performed when the positioning block is effectively attached to the bottle, avoiding poor transfer caused by bottle displacement.
