Description

Technical Field

[0001] The invention relates to the field of sealing strip installation equipment, and more particularly to a pressure wheel device. Background Art

[0002] A Chinese patent with publication number CN206932718U discloses a temperature-controlled atmosphere device for a shallow circular silo, which discloses a method of using a grain film to seal the wall of the atmosphere-controlled silo: first, a double-groove pipe with two annular closed grooves is fixedly installed on the wall surface that needs to be sealed, and first, the edge of the grain film (i.e., film) is laid on the double-groove pipe, and then the four sides of the grain film are sealed and embedded in the groove of the double-groove pipe with a sealing strip (i.e., a sealing strip).

[0003] At present, the above-mentioned shallow silo temperature control and gas conditioning equipment is usually installed by using an existing roller press. The roller of the roller press is placed against the double-grooved tube and moved along the extension direction of the double-grooved tube, so that the sealing strip and the grain film are squeezed into the groove of the double-grooved tube together, so that the edge of the grain film is sealed and clamped between the double-grooved tube and the sealing strip. In actual operation, the following problems occur: (1) Since the grain film and the sealing strip are squeezed into the groove together, the grain film is easily stretched and deformed, or even damaged, and it takes a lot of effort to squeeze the grain film and the sealing strip into place, which is labor-intensive and causes low work efficiency. It is also easy to cause the sealing strip to be installed in place, affecting the sealing effect. (2) When squeezing and installing the sealing strips on the bottom or left and right sides, the grain film sags due to the influence of gravity, which makes it easy for the grain film to move and increases the difficulty of installation. At the same time, the sagging of the grain film will also block the operator's line of sight, so other personnel are usually required to turn up the grain film and press it on the wall by hand, resulting in increased labor costs and affecting work efficiency. Therefore, in order to solve the above problems, it is necessary to design a roller device specifically for the rapid sealing of grain film. Summary of the invention

[0004] The present invention provides a pressure wheel device, aiming to solve the above problems existing in the prior art.

[0005] The present invention adopts the following technical solution:

[0006] A pressing wheel device comprises a frame, a first pressing wheel and a second pressing wheel. The front end of the frame is provided with at least one of the first pressing wheels for pressing a film into a slot. The frame is provided with at least one of the second pressing wheels for pressing a sealing strip into a slot directly behind each of the first pressing wheels.

[0007] Furthermore, it also includes a baffle, which is horizontally arranged on the frame and is used to prevent the film from approaching the frame.

[0008] Furthermore, the baffle is arranged at the front end of the left side of the frame, and a flange is provided at one end of the baffle away from the frame.

[0009] Furthermore, the circumferential surface of the first pressing wheel is provided with an annular protrusion for being embedded in the clamping groove.

[0010] Furthermore, the circumferential surface of the second pressure wheel is provided with an annular recess for embedding with the sealing strip.

[0011] Furthermore, the skeleton is provided with two second pressing wheels arranged directly behind each first pressing wheel, and the axis center line of the preceding second pressing wheel is higher than or equal to the axis center line of the following second pressing wheel.

[0012] Furthermore, the second pressing wheel can be arranged on the frame in a floating manner up and down.

[0013] Furthermore, the frame is provided with two first pressing wheels which are arranged at intervals along the left-right direction.

[0014] Furthermore, the cross-sectional profile of the skeleton along the left-right direction is roughly in the shape of a concave letter "U".

[0015] Furthermore, a hand-holding portion is provided on the upper end surface of the frame.

[0016] Furthermore, the axis center line of the first pressing wheel is lower than the axis center line of the second pressing wheel.

[0017] From the above description of the structure of the present invention, it can be seen that the present invention has the following advantages:

[0018] First, the present invention includes a frame, a first pressing wheel and a second pressing wheel. The front end of the frame is provided with at least one first pressing wheel for pressing a film into a card slot, and the frame is provided with at least one second pressing wheel for pressing a sealing strip into a card slot directly behind each first pressing wheel. The film is first pressed into the card slot of the double-grooved tube using the first pressing wheel, and then the sealing strip is pressed into the card slot of the double-grooved tube using the second pressing wheel, which can avoid damage to the film, and the operation is simple and labor-saving.

[0019] Secondly, the present invention also includes a baffle plate horizontally arranged on the frame, which is used to press the folded and drooped film against the wall to prevent the film from blocking the operator's sight.

[0020] Third, in the present invention, two second pressing wheels are arranged on the frame directly behind each first pressing wheel, and the first second pressing wheel can be arranged on the frame in a floating manner. The first second pressing wheel can initially press the sealing strip into the slot to avoid damaging the film by excessive force, and the second second pressing wheel can ensure that the sealing strip is completely slotted to avoid the problem of improper installation of the sealing strip.

[0030] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0031] Embodiment 1

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig. 9 A pressing wheel device comprises a frame 3, a first pressing wheel 2, a second pressing wheel 4 and a baffle 1. The cross-sectional profile of the frame 3 along the left and right directions is roughly in the shape of a concave character, and a hand-held portion 5 is provided on the upper end surface of the frame 3, so that people can conveniently hold and operate the pressing wheel device. The frame 3 and the hand-held portion 5 can be integrally formed, or can be two parts fixedly connected by screws or welding, and can be made of conventional materials such as aluminum alloy, iron, plastic, wood, etc. that are light in weight and convenient for mass production.

[0033] like Figures 1 to 3 A first pressing wheel 2 is provided at the front end of the frame 3 for pressing the film a2 into the slot a11 of the double-slot tube a1. Specifically, a circular surface of the first pressing wheel 2 is provided with an annular protrusion 21 for being embedded in the slot a11.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig. 9 The skeleton is provided with two second pressing wheels 4 arranged in a front-to-back direction directly behind the first pressing wheel 2, for pressing the sealing strip a3 into the card slot a11. Specifically, the circumferential surface of the second pressing wheel 4 is provided with an annular recess 41 for embedding with the sealing strip a3. Preferably, the cross-sectional profile of the annular recess 41 is semicircular.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig. 9 Preferably, the axis center line of the first pressing wheel 2 is lower than the axis center lines of the two second pressing wheels 4, so as to ensure that the first pressing wheel 2 can better clamp the film a2 into the slot a11.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig. 9 Preferably, the axis of the first second pressing wheel 4 is higher than or equal to the axis of the second pressing wheel 4. The first second pressing wheel 4 can initially press the sealing strip a3 into the slot a11 to avoid damaging the film a2 by excessive force, and the second pressing wheel 4 can ensure that the sealing strip a3 is completely inserted into the slot a11 to avoid the problem of improper installation of the sealing strip a3.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig. 9 , the previous second pressure wheel 4 can be arranged on the skeleton 3 in a floating manner up and down, providing a certain buffer process for the previous second pressure wheel 4 and the sealing strip a3, and avoiding damage to the film a2. Specifically, both ends of the previous second pressure wheel 4 can be arranged on the skeleton 3 in a floating manner up and down through a spring reset mechanism 5. The spring reset mechanism 5 mainly includes a sleeve 54, a movable rod 53, a mounting seat 51 and a spring 53. Among them, the sleeve 54 is fixedly connected to the side wall of the skeleton 3, the movable rod 53 can be movably arranged in the sleeve 54 up and down, the upper end of the movable rod 53 is fixedly connected to the limited position block, and the lower end is sleeved with a spring 53, and is fixedly connected to the mounting seat 51. And the upper end of the spring 53 is supported by the sleeve 54, and the lower end is supported by the mounting seat 51. The mounting seat 51 is provided with a blind hole for rotatably installing the rotating shaft of the previous second pressure wheel 4. At the same time, the two second pressing wheels 4 arranged in front and behind of the material use the principle of positioning two points in a straight line to allow the sealing strip a3 between the two second pressing wheels 4 to be located between the card grooves a11, so that the sealing strip a3 and the card groove a11 remain aligned, reducing the difficulty of operation.

[0038] like Figure 1, Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig. 9 , one end of the baffle 1 is arranged on the frame 3, and is used to prevent the film a2 from approaching the frame 3. Specifically, one end of the baffle 1 is horizontally fixed on the frame 3 by welding or screw assembly, and is located at the left front end or the right front end of the frame 3. Preferably, the other end of the baffle 1 is provided with a flange, so that a larger space can be reserved between the sagging film a3 and the roller press, providing people with a better field of vision, and also preventing the baffle 1 from scratching the film a3 when it moves. Of course, the baffle 1 can also be installed at other positions of the frame 3, as long as the baffle 1 can make the film a2 attached to the roller press close to the wall b, so as to better assist in fixing the film a2 and prevent the film a2 from moving due to sagging due to gravity or blocking the operator's line of sight.

[0039] Embodiment 2

[0040] like Figures 1 to 9 The difference between the second embodiment and the first embodiment is that: the frame 3 is provided with two first pressing wheels 2 arranged at intervals in the left-right direction, and two second pressing wheels 4 are arranged directly behind each first pressing wheel 2. In this way, in one operation, two sealing strips can be simultaneously placed in two mutually parallel card slots a11, reducing the number of operations and improving work efficiency.

[0041] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
