Description

Technical Field

[0001] The utility model relates to a clamping and sealing device for a feeding port of a new energy positive electrode material, and belongs to the technical field of production of new energy powder materials. Background Art

[0002] At present, bag openers, as an efficient and automated powder material feeding equipment, have been widely used in the field of new energy powder material production. It can quickly and accurately complete the feeding of powder or granular materials, improve production efficiency and reduce labor costs. However, the existing bag openers have the following shortcomings:

[0003] 1. The existing bag opening machine clamping device inflates the sealing air ring through air pressure, so that the sealing air ring expands and squeezes the bag opening and the feed port to prevent the material from leaking out. However, the sealing air ring is easily broken due to changes in the air source pressure, which takes time to replace again. It is also easy to pollute the material and affect production. The sealing ring is expensive. Therefore, it is necessary to solve the problem of easy rupture of the sealing ring to improve production automation and production efficiency.

[0004] 2. The existing bag opening machine cylinder is a single-axis lifting cylinder. Due to structural defects, the cylinder axis will deform after the cylinder has been running for a period of time, causing the cylinder to be unable to be used normally.

[0005] 3. The existing bag opening machine has great safety hazards during operation. There is no detection device, and the lifting cylinder is easy to hit the operator. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model proposes a clamping and sealing device for a feeding port of a new energy positive electrode material to solve the problems of rupture of the sealing air ring of the feeding port of the existing bag opening machine, easy failure of the cylinder, and safety hazards to operators during the production process.

[0007] The technical solution of the utility model: a clamping and sealing device for a feeding port of a positive electrode material of a new energy source, comprising two symmetrically installed cylinders, a mountain-shaped aluminum plate is fixedly connected to the piston rod of the cylinder, a semicircular clamp is fixedly connected to the mountain-shaped aluminum plate, a left-side semicircular silicone pad and a right-side semicircular silicone pad are respectively fixedly installed on the inner sides of the semicircular clamps on both sides, a card slot is opened at both ends of the left-side semicircular silicone pad, and a convex head matching the card slot is arranged at both ends of the right-side semicircular silicone pad.

[0008] Furthermore, the cylinder is a three-axis cylinder.

[0009] Furthermore, the cylinder is fixed on the cylinder base by cylinder fixing bolts.

[0010] Furthermore, the semicircular silicone pad is fixedly installed on the inner side of the semicircular clamp by using silicone pad fixing bolts.

[0011] Furthermore, the clamping and sealing device also includes an anti-pinch light curtain sensor symmetrically installed below the cylinder.

[0012] Due to the adoption of the above technical solution, the utility model has the following advantages:

[0013] 1. The utility model can clamp the material bag mouth on the discharge pipe of the bag opener to prevent material leakage during feeding, solve the problem of material leakage caused by the rupture of the sealing air ring during inflation during the feeding process, improve production efficiency, and eliminate the high cost of the sealing air ring.

[0014] 2. After replacing the three-axis cylinder, there is no need to lubricate the components. The three-axis cylinder does not need to use the copper sleeve lubrication components which have a huge impact on product quality, thus avoiding copper pollution and improving product quality.

[0015] 3. After adding the anti-pinch light curtain sensor, if there is an operator at the equipment operation port, the cylinder will not move, which greatly ensures the personal safety of the operator. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model is further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Example

[0027] See also Figures 1 to 6 The utility model discloses a clamping and sealing device for a feeding port of a positive electrode material of a new energy source, comprising two symmetrically installed cylinders 2, a mountain-shaped aluminum plate 8 is fixedly connected to the piston rod of the cylinder 2, a semicircular clamp 7 is fixedly connected to the mountain-shaped aluminum plate 8, a left semicircular silicone pad 5 and a right semicircular silicone pad 6 are fixedly installed on the inner sides of the semicircular clamps 7 on both sides, a card groove 11 is provided at both ends of the left semicircular silicone pad 5, and a convex head 12 matching the card groove is provided at both ends of the right semicircular silicone pad 6.

[0028] The cylinder 2 is a three-axis cylinder. Since the three-axis cylinder does not need a copper sleeve lubrication component, copper pollution is avoided and product quality is improved.

[0029] The cylinder 2 is fixed on the cylinder base 1 by cylinder fixing bolts 3, which is convenient for disassembly, assembly and replacement.

[0030] The semicircular silicone pad 6 is fixedly installed on the inner side of the semicircular clamp 7 by using silicone pad fixing bolts 4, which is convenient for installation and maintenance.

[0031] The clamping and sealing device also includes an anti-pinch light curtain sensor 9 symmetrically installed below the cylinder 2. If an operator is at the operating port of the equipment, the cylinder 2 will not move, which greatly ensures the personal safety of the operator.

[0032] The working principle of this utility model:

[0033] See also Figure 7 and Figure 8 First, the cylinder 2 is fixedly mounted on the bag opener clamping device 10 through the cylinder base 1, and two anti-pinch light curtain sensors 9 are also symmetrically fixedly mounted on the bag opener clamping device 10. In order to realize automatic control, the opening and closing of the cylinder 2 is controlled by the solenoid valve, and the solenoid valve and the anti-pinch light curtain sensor 9 are controlled by the controller.

[0034] During operation, the solenoid valve is started by the controller, and the solenoid valve opens after being energized, and compressed air enters the cylinder 2 through the solenoid valve. The piston rods of the cylinders 2 on both sides push the left semicircular silicone pad 5 and the right semicircular silicone pad 6 horizontally toward each other until the slot 11 on the left semicircular silicone pad 5 and the convex head 12 on the right semicircular silicone pad 6 match, so that the material bag opening and the discharge pipe of the bag opener can be clamped. After the feeding is completed, the solenoid valve is closed by the controller. When the solenoid valve loses power, the piston rod pushes in the opposite direction to loosen the left semicircular silicone pad 5 and the right semicircular silicone pad 6.

[0035] The utility model clamps the material bag opening on the feeding pipe of the bag opener through the left semicircular silicone pad 5 and the right semicircular silicone pad 6, preventing material leakage during feeding, solving the problem of material leakage caused by the rupture of the sealing air ring during inflation during feeding, improving production efficiency, and eliminating the high cost of the sealing air ring. At the same time, after adding the anti-pinch light curtain sensor 9, if there is an operator at the equipment operation port, the controller will not start the solenoid valve, and the cylinder 2 will not move, which greatly guarantees the personal safety of the operator.

[0036] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. For those skilled in the art, the technical solution recorded in the above embodiments can be improved and modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the utility model.
