At the same time, there is some residual material on the plug board, posing a risk of material leakage. Content of the Utility Model

[0003] The purpose of the utility model is to provide a manual sealing gate in view of the defects and deficiencies of the prior art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a manual sealing gate, including a housing. A plurality of nylon rollers are equidistantly arranged on the upper and lower inner walls of the housing. The innovation lies in that: a partition is arranged on the front surface of the housing, vertical seat bearings are arranged on the back surface of the partition and the left side surface of the housing. A lead screw is arranged between the vertical seat bearings. One end of the lead screw is connected to a hand wheel. A nut block is threadedly connected to the lead screw. The nut block is fixedly provided with a plug board. The partition divides the housing into left and right sides. And a limiting strip is correspondingly arranged for the nylon rollers on the right side. The upper and lower ends of the plug board are located between the nylon rollers and the limiting strip, and guide the plug board. And an extrusion mechanism with an eccentric structure is arranged between the nylon rollers on the right side and on the right side surface of the housing. The extrusion mechanism extrudes the plug board to make it away from the nylon rollers; Two groups of sealing members are arranged on the front and back surfaces of the plug board.

[0005] Further, the extrusion mechanism includes a mounting plate, the mounting plate is fixed outside the housing by bolts, a bushing is arranged on the mounting plate, a locking shaft is arranged inside the bushing, one end of the locking shaft extends into the housing and is provided with an eccentric wheel, and the eccentric wheel extrudes the plug board when rotating. The other end of the locking shaft is of a square shaft structure.

[0006] Further, one group of the sealing members is a pair of sealing plates, the sealing plates respectively abut against the front and back surfaces of the plug board, and the other sealing member is a rubber strip, and the rubber strip is attached to the back surface of the plug board.

[0007] After adopting the above structure, the beneficial effects of the utility model are as follows:

[0008] The utility model squeezes the plug board through a squeezing mechanism. Since the plug board has a certain elasticity, when it is squeezed, it moves away from the nylon roller. When the nylon roller is not under pressure, it is convenient to disassemble and replace. At the same time, the tightness between the nylon roller and the plug board can be adjusted through the squeezing mechanism, reducing the jamming of the movement of the plug board and improving the applicability of the gate; by setting two sets of sealing components, the materials on the plug board can be scraped off, improving the sealing performance and avoiding the risk of material leakage.

Detailed Embodiment

[0013] The following further describes the utility model with reference to the drawings.

[0014] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further details the utility model in combination with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0015] Refer to Figure 1-2, A manual sealing gate, comprising a housing 1. A plurality of nylon rollers 2 are equidistantly arranged on the upper and lower inner walls of the housing 1. A partition 3 is arranged on the front surface of the housing 1. Vertical seat bearings 4 are arranged on the back surface of the partition 3 and the left side surface of the housing. A lead screw 5 is arranged between the vertical seat bearings 4. One end of the lead screw 5 is connected to a handwheel 6. A nut block 7 is threadedly connected to the lead screw 5. The nut block 7 is fixedly provided with an insertion plate 8. The partition 8 divides the housing into left and right sides. And a limiting strip 9 is correspondingly arranged for the nylon rollers 2 on the right side. The upper and lower ends of the insertion plate 8 are located between the nylon rollers 2 and the limiting strip 9 and guide the insertion plate 8. And an extrusion mechanism 10 with an eccentric structure is arranged between the nylon rollers on the right side and on the right side surface of the housing. The extrusion mechanism 10 extrudes the insertion plate 3 to make it away from the nylon rollers 2; Two groups of sealing members are arranged on the front and back surfaces of the insertion plate 3. Specifically, by rotating the handwheel 6 to rotate the lead screw 5, the rotation of the lead screw 8 drives the nut block 7 to move left and right, that is, drives the insertion plate 8 to move to realize opening and closing; When the nylon rollers 2 need to be disassembled, only need to extrude the extrusion mechanism 10 to make it extrude the insertion plate 8. Since the insertion plate 8 has a certain elasticity, when being extruded, local deformation occurs, making it away from the nylon rollers 2. When the nylon rollers 2 are not under pressure, it is convenient to disassemble and replace them.

[0016] In this embodiment, the extrusion mechanism 10 includes a mounting plate 101. The mounting plate 101 is fixed to the outside of the housing 1 by bolts. A bushing 102 is arranged on the mounting plate 101. A locking shaft 103 is arranged inside the bushing 102. One end of the locking shaft 103 extends into the housing and is provided with an eccentric wheel 104. When the eccentric wheel 104 rotates, it extrudes the insertion plate 8. The other end of the locking shaft 103 is of a square shaft structure. By rotating the locking shaft 103, the eccentric wheel 104 is driven to rotate. The eccentric wheel 104 extrudes the insertion plate 8. Since the insertion plate 8 has a certain elasticity, when being extruded, local deformation occurs, making it away from the nylon rollers 2. When the nylon rollers 2 are not under pressure, it is convenient to disassemble and replace them. At the same time, the tightness between the nylon rollers and the insertion plate can be adjusted through the extrusion mechanism, reducing the jamming during the movement of the insertion plate and improving the applicability of the gate.

[0017] In this embodiment, one group of the sealing members is a pair of sealing plates 11. The sealing plates 11 respectively abut against the front and back surfaces of the insertion plate 8. The other sealing member is a rubber strip 12. The rubber strip 12 is attached to the back surface of the insertion plate 8 (see Figure 2 ). During the left and right movement of the insertion plate 8, by arranging the sealing plates 11 and the rubber strip 12, the materials on the insertion plate 8 can be scraped off. The rubber strip 12 can improve the sealing performance and avoid the risk of material leakage; The sealing plates 11 are respectively installed on the back of the partition and the back plate of the housing. The rubber strip 12 is also installed on the back plate of the housing.

[0018] The above are only used to illustrate the technical solution of the present utility model rather than to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model shall be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
