Description

Technical Field

[0001] This utility model relates to the technical field of conveying devices, and more specifically, to a film conveying device for a combined inner cover film covering device. Background Technology

[0002] Plastic combination caps, widely used in food, pharmaceutical, and other packaging applications, consist of a ring-shaped rigid plastic cap and a circular, sheet-like soft plastic film. This structural design provides them with good structural rigidity, reliable sealing, and ease of opening for the user.

[0003] In its production process, the rigid plastic part and the flexible plastic film part need to be prepared separately first, and then the two are tightly bonded together through a hot pressing process. Since the hot pressing process is usually carried out continuously, the flexible plastic film must also be produced and transported synchronously and continuously. Considering that the flexible film itself has a small diameter, if it is produced in large quantities in advance and stored, it is very easy to deform or become contaminated during the turnover due to stacking and friction. Therefore, the most suitable process is to adopt a "produce-as-you-go" mode, that is, to put it into the subsequent lamination process immediately after it is formed.

[0004] In the specific process, after the plastic film is formed by the punching device, it needs to be accurately and stably transferred to the hot pressing device for bonding. Since the hot pressing process is continuous, the conveying of the film must also be continuous. However, due to its extremely thin thickness, small size, and light weight, the plastic film is easily affected by external factors such as airflow, mechanical vibration, or electrostatic adsorption during the transfer process, which can lead to problems such as drifting, rolling, or mispositioning, seriously affecting the quality and efficiency of subsequent hot pressing.

[0005] Therefore, in order to achieve a smooth and efficient overall production process for plastic composite caps, it is urgent to design a special conveying device suitable for such lightweight and thin soft films. Utility Model Content

Detailed Implementation

[0019] Example The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 - Appendix Figure 5As shown, the film conveying device for the combined inner cover film covering device of this embodiment includes a base plate 10, a support plate 11 horizontally disposed on the base plate 10, a first driving device for driving the support plate 11 to rotate along a vertical axis, a plurality of adsorption devices 20 disposed on the upper edge of the support plate 11, and a negative pressure device connected to the plurality of adsorption devices 20 simultaneously; the plurality of adsorption devices 20 are circumferentially distributed, and each adsorption device 20 includes a hollow negative pressure box 21, a plurality of negative pressure holes 22 opened at the upper end of the negative pressure box 21, and a negative pressure pipe communicating with the side wall of the negative pressure box 21; the negative pressure pipe is connected to the negative pressure device. Specifically, during use, the cutting device 40 cuts the plastic film and drops it onto the upper part of the negative pressure box 21. Since the negative pressure box 21 is connected to a negative pressure device that continuously generates negative pressure inside, the plastic film is adsorbed onto the upper part of the negative pressure box 21. Then, the first driving device drives the support plate 11 to rotate, thereby transferring the plastic film to subsequent processing steps, achieving the purpose of transferring the plastic film. This device allows for continuous and uninterrupted transfer of the plastic film. Furthermore, the structure of the negative pressure box 21 allows it to adsorb plastic films of various types and sizes, and an appropriate number of negative pressure devices can be installed as needed, thus providing better adaptability. With simple adjustments, it can be applied to various production processes. It should be noted that this embodiment only designs the plastic film transfer device; therefore, the cutting device 40 and other equipment are only shown in relative position.

[0020] The adsorption device 20 in this embodiment also includes a connecting plate 23 fixedly disposed at the lower end of the negative pressure box 21, and the connecting plate 23 is detachably connected to the support plate 11. Specifically, this allows for convenient adjustment of the position of the negative pressure box 21.

[0021] In this embodiment, the negative pressure box 21 has a connecting pipe 24 on its side wall, which is detachably connected to the negative pressure pipe; an air inlet pipe 25 is provided on the side of the negative pressure box 21 away from the connecting pipe 24. Specifically, the connecting pipe 24 allows for quick installation and removal from the negative pressure pipe, achieving a quick-release structure.

[0022] In this embodiment, the connecting pipe 24 and the air inlet pipe 25 are coaxially arranged. A connecting rod 26 is provided inside the air inlet pipe 25, and a first ball head 27 and a second ball head 28 are fixedly mounted on the connecting rod 26. A second driving device 30 is also included to drive the connecting rod 26 to move axially. Both the first ball head 27 and the second ball head 28 are located inside the negative pressure box 21, with the first ball head 27 positioned near the connecting pipe 24 and the second ball head 28 positioned near the air inlet pipe 25. The first ball head 27 can close the connecting pipe 24, and the second ball head 28 can close the air inlet pipe 25. Specifically, when the plastic film needs to be removed from the negative pressure box 21, the negative pressure in the negative pressure box 21 needs to be removed. Therefore, outside air needs to be introduced through the air inlet pipe 25 to balance the air pressure inside and outside the negative pressure box 21, thus enabling better suction of the plastic film from the negative pressure box 21. This operation is primarily accomplished through the first ball head 27 and the second ball head 28. The second drive device 30 moves the connecting rod 26. When the first ball head 27 is attached to the connecting pipe 24, the negative pressure pipe can no longer draw negative pressure from the negative pressure chamber, and the second ball head 28 moves away from the air inlet pipe 25, allowing outside air to enter the negative pressure chamber 21. The second drive device 30 then pushes the connecting rod 26 in the opposite direction. At this point, the first ball head 27 moves away from the connecting pipe 24, and the second ball head 28 blocks the air inlet pipe 25. The negative pressure device then draws negative pressure from the negative pressure chamber 21 through the negative pressure pipe. By reciprocating along its axis, the connecting rod 26 can perform continuous air extraction and intake operations.

[0023] In this embodiment, the connecting rod 26 is provided with a first magnetic plate 31 at one end outside the air intake pipe 25. A spring 32 is sleeved on the air intake pipe 25. One end of the spring 32 is connected to the first magnetic plate 31, and the other end is fixedly connected to the outer wall of the negative pressure box 21. The second driving device 30 includes a vertically arranged top rod and a second magnetic plate 33 at the upper end of the top rod. The top rod passes through the support plate 11 and is slidably connected to the support plate 11. The second magnetic plate 33 is arranged close to a magnetic plate, and the sides of the first magnetic plate 31 and the second magnetic plate 33 that are close to each other are mutually repulsive. The second driving device 30 also includes a third magnetic plate 35 at the lower end of the top rod. A magnetic seat 36 is provided above the base plate 10. The upper side of the magnetic seat 36 and the lower side of the third magnetic plate 35 are mutually repulsive. The magnetic seat 36 is fixedly connected to the base plate 10 through a support rod 37. Specifically, when the negative pressure box 21 rotates to the magnetic base 36, the magnetic base 36 generates an upward repulsive force on the third magnetic piece 35, causing the third magnetic piece 35, the push rod, and the second magnetic piece 33 to move upward. Then, the second magnetic piece 33 approaches the first magnetic piece 31, thereby pushing the first magnetic piece 31, the connecting rod 26, the first ball head 27, and the second ball head 28 to move, causing the first ball head 27 to block the connecting pipe 24 (as shown in the attached diagram). Figure 4As shown in the figure, outside air enters the negative pressure box 21 through the air intake pipe 25. When the negative pressure box 21 leaves the magnetic base 36, the third magnetic plate 35 loses its upward thrust and falls downward. Then, the second magnetic plate 33 leaves the first magnetic plate 31, the first magnetic plate 31 loses its thrust, and the first magnetic plate 31, connecting rod 26, first ball head 27 and second ball head 28 move under the thrust of spring 32, causing the first ball head 27 to leave the connecting pipe 24 and the second ball head 28 to block the air intake pipe 25 (as shown in the figure). Figure 5 As shown), negative pressure can continue to be generated at this time. By extending the length and range of the magnetic base 36, negative pressure can be generated only when the negative pressure box 21 needs to adsorb the plastic film.

[0024] In this embodiment, both the first ball head 27 and the second ball head 28 are provided with a rubber layer. Specifically, the rubber layer can better block the connecting pipe 24 or the air inlet pipe 25.

[0025] The first driving device in this embodiment includes a motor 12 mounted on a base plate 10, and the drive shaft of the motor 12 is fixedly connected to a support plate 11.

[0026] In summary, the film conveying device of the combined inner cover film covering device of this embodiment, when in use, the cutting device 40 cuts the plastic film and drops it onto the upper end of the negative pressure box 21. Since the negative pressure box 21 is connected to a negative pressure device, a negative pressure can be continuously generated inside the negative pressure box 21. Therefore, the plastic film will be adsorbed onto the upper end of the negative pressure box 21. Then, the first driving device drives the support plate 11 to rotate, thereby transferring the plastic film to the subsequent processing steps, achieving the purpose of transferring the plastic film. This device can continuously and uninterruptedly perform the plastic film transfer operation. Furthermore, the structure of the negative pressure box 21 allows it to adsorb plastic films of various types and sizes, and an appropriate number of negative pressure devices can be installed as needed. Therefore, it has better adaptability and can be applied to various production processes with simple adjustments.
