Description

Technical Field

[0001] This utility model belongs to the field of automation equipment technology, and specifically relates to a plastic sheet alternating feeding bin. Background Technology

[0002] In 3C products, long adhesive strips typically refer to thin, strip-shaped components made of rubber or plastic used for sealing, shock absorption, and cushioning. 3C long adhesive strips possess excellent elasticity, sealing properties, and weather resistance. They can be used for sealing and shock absorption in electronic products such as mobile phones and computers. For example, using adhesive strips in the gaps of mobile phone frames and computer casings can prevent dust and moisture from entering the device, while also acting as a buffer to reduce damage from impacts. During the manufacturing process of 3C products, long adhesive strips are installed in various ways; some are directly pasted onto device components using adhesive backing, while others are embedded in specific slots.

[0003] In the production process of 3C long adhesive strips, because they are very thin plastic sheets, they easily stick together due to static electricity. During use, they need to be separated manually, one sheet at a time, which is extremely inefficient. Automated equipment lacks effective separation methods, and the equipment often retrieves two or more plastic sheets at a time, which does not meet production requirements. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above deficiencies, the purpose of this utility model is to provide a plastic sheet alternating feeding hopper to solve the above technical problems.

[0005] Technical solution: To achieve the above objectives, this utility model provides a plastic sheet alternating feeding bin, comprising: Mounting bracket, on which a mounting base plate is slidably mounted; At least one set of hoppers, the hoppers being mounted on a mounting base plate, the hoppers including a vertically sliding support plate mounted on the mounting base plate, side baffles and end baffles mounted on the mounting base plate, the side baffles and end baffles surrounding the support plate to form a hopper body for accommodating plastic sheets; The side baffle is provided with a number of air holes on the side facing the hopper body, and the top of the side baffle is provided with a sheet separation device, which includes a separation block and an auxiliary block on a set of opposite side baffles; The separating block has an inclined stepped toothed surface on the side facing the hopper, while the auxiliary block has a smooth arc surface on the side facing the hopper. The lifting device includes a lifting cylinder mounted on a mounting bracket, which can lift the support plate. The chamber changing device includes a chamber changing cylinder mounted on a mounting bracket. The chamber changing cylinder is connected to a mounting base plate and can drive the mounting base plate to slide on the mounting bracket.

[0006] Furthermore, the lifting device also includes a mounting plate horizontally disposed on the mounting bracket, a lifting cylinder mounted on the mounting plate, and a transition plate connected to the piston rod of the lifting cylinder passing through the mounting plate. A set of push rods is provided at both ends of the transition plate, the push rods passing through the mounting plate and having a top block at their top. The lifting cylinder drives the transition plate to move up and down, thereby causing the push rods to move up and down, and the top block at the end of the push rod lifts the supporting plate.

[0007] Furthermore, the mounting plate is provided with a guide sleeve, through which the push rod passes. A set of sensing brackets is positioned opposite each other at the bottom of the mounting plate. The sensing brackets are equipped with first photoelectric sensors at different heights. First sensing plates, matching the first photoelectric sensors, are located on both sides of the transition plate. The push rod, passing through the guide sleeve on the mounting plate, guides its vertical movement, enabling it to smoothly raise and lower the support plate. The height difference between the first photoelectric sensors at different heights corresponds to the stroke of the support plate.

[0008] Furthermore, the chamber-changing cylinder is a rodless cylinder. The moving slider of the chamber-changing cylinder is connected to the mounting base plate. The moving slider is equipped with a second sensing plate. The side of the mounting bracket is equipped with a set of second photoelectric sensors that match the second sensing plate. The two second photoelectric sensors correspond to the positions of the two chambers respectively. By sensing the position of the second sensing plate through the second photoelectric sensors, the chambers can be accurately stopped at the lifting position.

[0009] Furthermore, the bottom surface of the mounting base plate is equipped with a photoelectric sensor for detecting plastic sheets, and the mounting base plate is also equipped with guide rods, with both ends of the support plate sleeved on the guide rods. When plastic sheets are placed in the hopper, they will block the light emitted by the photoelectric sensor at the bottom, thus being detected. The guide rods guide the support plate, ensuring the verticality of the support plate during lifting and lowering.

[0010] Furthermore, the mounting bracket is provided with a linear slide rail, and the bottom of the mounting base plate is provided with a slider, which is slidably mounted on the linear slide rail.

[0011] Furthermore, the mounting bracket is also equipped with a set of ion fans, the air outlets of which face the material hopper. The ion fans blow gas carrying ions onto the plastic sheets in the hopper, further solving problems such as dust attraction and adhesion caused by static electricity on the plastic sheets.

[0012] As can be seen from the above technical solution, this utility model has the following beneficial effects: 1. This utility model discloses a plastic sheet alternating feeding hopper, which has a simple structure and reasonable design. The side baffle of the hopper is provided with air holes. When the plastic sheet is lifted, air is blown through the air holes to separate it. A sheet separation device is also provided at the outlet of the hopper. The plastic sheet is completely separated into individual pieces by the cooperation of the stepped tooth surface on the separation block and the arc-shaped surface on the auxiliary block. At the same time, an ion fan is used to remove static electricity from the plastic sheet. When picking up the plastic sheet, it is ensured that the plastic sheet does not stick together and only individual pieces are picked up, which is more in line with modern automated equipment.

[0013] 2. This utility model includes at least two hoppers. By setting up induction plates and photoelectric sensors, the automatic alternating feeding of the hoppers is realized. The equipment has a high degree of automation. At the same time, the integration of dual hoppers avoids the need for downtime for material replenishment and saves installation space.

Detailed Implementation

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] In this embodiment, as Figures 1 to 6 This utility model discloses a plastic sheet alternating feeding bin, comprising: Mounting bracket 1, on which mounting base plate 2 is slidably mounted; At least one set of hoppers 3, the hoppers are mounted on the mounting base plate 2, the hoppers 3 include a vertically sliding support plate 31 mounted on the mounting base plate 2, side baffles 32 and end baffles 33 mounted on the mounting base plate 2, the side baffles 32 and end baffles 33 surround the support plate 31 to form a hopper body for accommodating plastic sheets; The side baffle 32 has a plurality of air holes 34 on the side facing the hopper body, and the top of the side baffle 32 is provided with a sheet separation device, which includes a separation block 61 and an auxiliary block 62 disposed on a set of side baffles 32 in opposite positions. The separating block 61 has an inclined stepped toothed surface facing the hopper body, and the auxiliary block 62 has a smooth arc surface facing the hopper body. The lifting device 4 includes a lifting cylinder 41 mounted on the mounting bracket 1, which can lift the support plate 31. The chamber changing device 5 includes a chamber changing cylinder 51 mounted on the mounting bracket 1. The chamber changing cylinder 51 is connected to the mounting base plate 2 and can drive the mounting base plate 2 to slide on the mounting bracket 1.

[0018] In this embodiment, plastic sheets are stacked in a hopper formed by side baffles 32 and end baffles 33 surrounding a support plate 31. The support plate 31 and the plastic sheets on it are lifted by a lifting cylinder in the lifting device 4 to prepare for retrieval in the next process. When the total amount of plastic sheets in the hopper 3 rises to the top of the side baffles 32, airflow from the air holes inside the side baffles 32 separates the plastic sheets. As the plastic sheets exit the hopper 3, they contact the stepped toothed surface of the separating block 61 and, with the cooperation of the auxiliary block 62, are completely separated into single pieces. This ensures that only a single plastic sheet is retrieved per retrieval. After the plastic sheets in one hopper 3 are used up, the other hopper 3 is moved below the lifting device 4 via the hopper-changing device 5 to retrieve the plastic sheets from the other hopper 3.

[0019] Preferred embodiments, such as Figure 5As shown: The lifting device 4 further includes a mounting plate 42 horizontally arranged on the mounting bracket 1. The lifting cylinder 41 is mounted on the mounting plate 42. The piston rod of the lifting cylinder 41 passes through the mounting plate 42 and is connected to a transition plate 43. A set of push rods 44 are provided at both ends of the transition plate 43. The push rods 44 pass through the mounting plate 42 and have a top block 45 on their top. The lifting cylinder 41 drives the transition plate 43 to rise and fall. The push rods 43 on both sides of the transition plate 43 move up and down, and the top block 45 on the top of the push rods 43 simultaneously lifts or lowers the bearing plate 31.

[0020] In a further optimized design, the mounting plate 42 is provided with a guide sleeve, through which the push rod 44 passes. A set of sensing brackets 46 are positioned opposite each other at the bottom of the mounting plate 42. The sensing brackets 46 are equipped with first photoelectric sensors 47 at different heights. The transition plate 43 has first sensing plates 48 on both sides, corresponding to the first photoelectric sensors 47. When the first photoelectric sensor 47 at a high position senses the first sensing plate 48, it indicates that the push rod 43 has raised the support plate 31 to its highest position, and the lifting cylinder 41 controls it to stop rising. Similarly, when the first photoelectric sensor 47 at a low position senses the first sensing plate 48, it indicates that the push rod 43 has returned to its original position.

[0021] Preferred embodiments, such as Figure 6 As shown: The hopper-changing cylinder 51 is a rodless cylinder. The moving slider of the hopper-changing cylinder 51 is connected to the mounting base plate 2. The moving slider is equipped with a second sensing plate 52. The side of the mounting bracket 1 is equipped with a set of second photoelectric sensors 53 that match the second sensing plate 52. The two second photoelectric sensors correspond to the positions of the two hoppers respectively. During hopper changing, the moving slider on the hopper-changing cylinder 51 drives the mounting base plate 2 to move. When the second photoelectric sensor 53 detects the second sensing plate 52, it indicates that the hopper 3 has moved above the lifting device 4 and can be lifted.

[0022] The mounting base plate 2 is provided with a photoelectric sensor 21 for detecting plastic sheets on its bottom surface. The mounting base plate 2 is also provided with a guide rod 22, and the two ends of the bearing plate 31 are sleeved on the guide rod 22.

[0023] Specifically, the mounting bracket 1 is provided with a linear slide rail, and the bottom of the mounting base plate 2 is provided with a slider, which is slidably mounted on the linear slide rail.

[0024] Specifically, the mounting bracket 1 is also equipped with a set of ion fans 7, and the air outlet of the ion fans 7 faces the silo.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
