Description

Clamping tool

Technical Field

The present invention relates to a clamping tool that can clamp a plate material such as a water seal plate, and particularly, to a clamping tool that is a tool clamp, and more particularly, to a water seal plate used for replacing a coating machine in the field of maintenance of the coating machine.

Background

The coating machine is mainly used for coating the surfaces of products such as films, paper and the like, and has wide application in the electronic industry, the shoe industry, the paper industry, the plastic industry and the like.

The coating machine mainly comprises an unwinding roller, a winding roller, a coating device, a drying device and other stations between the unwinding roller and the winding roller, so that specific coatings (such as glue, paint, ink and the like) can be coated on coiled substrates (such as paper, films and the like), the coated substrates are dried, and the dried substrates are wound.

Some types of coating machines include a water seal plate having openings, such as bar-shaped openings, formed therein through which coating material can be transferred to a coating reel on a coating apparatus. And the side edge of the water seal plate is in sealing fit with the rumble surface of the coating rumble. Like this, through the water seal board, can ensure that the coating is even and apply to the coating rumble steadily, and then guarantee the stable coating weight to the substrate surface.

In the case of the existing coating machine including the water seal plate type, deposits such as latex, particles and the like in the coating material gradually accumulate in the openings of the water seal plate after a long period of use, and eventually block the openings, and such blocking affects the uniformity of coating on the substrate, and even when the blocking is serious, causes the coating operation to be not performed normally.

Therefore, the water seal plate of the coater needs to be replaced regularly to ensure the normal and uniform coating operation. The conventional water seal plate replacement operation is to pull out the end of the water seal plate by the bare hand of an operator and then pull out the entire water seal plate from the coater using a jaw tool such as a vice.

The water sealing plate replacing method has some problems. One of them, the water seal board surface is glossy usually, and when cliping the water seal board with two pincers lips of tiger head pincers and outwards pulling the water seal board, the water seal board slips easily between two pincers lips of tiger head pincers. This requires the operator to clamp the water seal plate with vice-head pliers again, which results in troublesome operations for replacing the water seal plate. Moreover, if the water seal plate slips when the water seal plate is about to be completely pulled out, the water seal plate is easy to fall, and potential safety hazards are caused.

Therefore, in the field of coating machines, there is a need for improvement in the replacement operation of the water seal plate so that the water seal plate is easily pulled out from the coating machine, thereby improving safety during the operation.

SUMMERY OF THE UTILITY MODEL

The present invention has been made to solve the above-mentioned problems occurring in the prior art. The utility model aims at providing a modified tool pliers to can dismantle the water seal board on the coating machine easily, in addition, still further can improve the operational safety nature.

The present invention relates to a jaw tool for clamping a sheet material having an opening, wherein the jaw tool comprises a first part and a second part, the first part comprising a first inner surface facing the second part, the second part comprising a second inner surface facing the first part. Wherein at least one tooth is formed on the first inner surface of the first member, wherein each tooth is shaped and positioned to mate with one of the openings in the sheet material

Thus, during the process of pulling out the plate material by using the tool with the structure, the plate material can be reliably locked by the matching between the convex teeth and the holes on the plate material, so as to better clamp the plate material, thereby keeping the water sealing plate stable during the pulling-out process. In this way, the risk of the sheet material accidentally falling off during being pulled out is substantially eliminated.

One specific example of such a jaw tool is a tool pliers that includes a pliers shank and a pliers mouth that includes, as first and second members, first and second pliers lips, the first pliers lip having a first inner surface and the second pliers lip having a second inner surface.

Preferably, at least one groove is formed on the second inner surface, wherein each tooth is shaped and positioned to correspond to one of the grooves. The convex teeth and the grooves can be embedded together, so that the locking of the water seal plate is further improved.

In a preferred construction, the number of teeth and grooves is the same, and/or the shape of the teeth is the same as the shape of the grooves. In this way, the teeth and grooves can be ideally fitted together.

Preferably, the height of the teeth is equal to or greater than the thickness of the sheet material. Thus, when the first and second parts are brought together, a gap sufficient for receiving the sheet material may be formed therebetween to better mate the clamping tool with the sheet material.

Preferably, in a specific application, the gap formed when the first member and the second member are folded is set within a range of 1 to 3mm, corresponding to the thickness of the plate.

Preferably, the teeth may be arranged to extend obliquely relative to the longitudinal axis of the first part.

More specifically, the angle between the teeth and the longitudinal axis is preferably set in the range of 90 ° to 150 °.

In the case where more than two teeth are included, the distance between two adjacent teeth is equal to the distance between two adjacent openings in the sheet material, or the distance between two adjacent teeth is a multiple of the distance between two adjacent openings in the sheet material. Thereby, it is ensured that each tooth fits into the opening in the sheet material.

Further, in order to better lock the sheet material during the drawing out of the water closing plate and to keep the sheet material stable during the drawing out, the number of the concave teeth is preferably set to be greater than or equal to three.

In a specific application, the plate clamped by the clamping tool can be a water seal plate of a coating machine, and the clamping tool is used for replacing the water seal plate.

Detailed Description

For the purpose of facilitating an understanding of the present invention, a preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. It is to be understood that only the preferred embodiment of the invention has been shown in the drawings and is not to be considered limiting of its scope. Various obvious modifications, changes and equivalents of the embodiments of the invention can be made by those skilled in the art based on the embodiments shown in the drawings, and all of them are within the protection scope of the invention.

Fig. 1 shows a preferred construction of a clamping tool of the present invention, in particular a tool clamp 100. The pliers 100 are formed by a pair of lever members having one end forming a pair of handles 110 of the pliers 100 and the other end forming a jaw 130 of the pliers 100. And, the pair of lever members are cross-coupled together by a clamp pin 121 at the clamp core 120 between the clamp handle 110 and the clamp nose 130 to form the tool clamp 100.

Of course, it is known to those skilled in the art that other known means of pivotally connecting the pair of lever members together at their intersection with each other may be used.

The tool pliers 100 are particularly useful for withdrawing a water sealing plate on a coater during maintenance of the coater as previously described.

Fig. 2 shows an enlarged view of the tool pliers 100 at one end of the pliers mouth 130. As shown in fig. 2, one end of the pair of lever members forming the jaw 130 of the tool pliers 100 is formed as a first jaw lip 131 and a second jaw lip 132 of the jaw 130, respectively. The first and

second lips

131, 132 have a pair of inner surfaces facing each other.

At least one tooth 133 is formed on the inner surface of the first jaw lip 131, and the at least one tooth 133 is shaped to fit into an opening formed in the water seal plate, such as to pass through the opening, preferably the tooth 133 is shaped to match the shape of the opening.

At least one groove 134 is formed on the inner surface of the second jaw lip 132. The teeth 133 of the first jaw lip 131 are shaped and positioned to correspond to a groove 134 on the second jaw lip 132. Here, the correspondence between the shape and the position means that the groove 134 can be fitted with the tooth 133 when the first lip 131 and the second lip 132 of the clip mouth 130 are closed. Or, in other words, as shown in fig. 2, the teeth 133 can be at least partially fitted in the grooves 134 in a state where the forceps jaws 130 are closed. Preferably, the shape of the teeth 133 is the same as that of the grooves 134, such as rectangular, and the teeth 133 are slightly smaller than the grooves 134, so that the teeth 133 can be inserted into the grooves 134.

It is also preferred that the number of teeth 133 and grooves 134 correspond, for example the number of grooves 134 may be a multiple of the number of teeth 133, and more preferably, the number of teeth 133 and grooves 134 are the same. Of course, the different number of the teeth 133 and the grooves 134 is also included in the scope of the present invention. For example, the number of teeth 133 is smaller than the number of grooves 134, so that some grooves 134 have corresponding teeth 133, and other grooves 134 have no corresponding teeth 133, which is not beyond the scope of the present disclosure.

Further, when the pincer mouth 130 is closed, a clearance C is preferably formed between the pair of inner surfaces of the first and second

pincer lips

131 and 132 which are opposed to each other. The size of the gap C is preferably larger than the thickness of the water sealing plate, for example, the gap C may be in the range of 1-3 mm, for example, the gap C may be 2 mm.

Fig. 3a shows a view along the line a-a in fig. 2, in which the inner surface of the first jaw lip 131 facing the second jaw lip 132 is shown, while fig. 3B shows a view along the line B-B in fig. 2, in which the inner surface of the second jaw lip 132 facing the first jaw lip 131 is shown.

As described above, at least one tooth 133 is formed on the inner surface of the first clip lip 131. Also, the teeth are preferably angled relative to the longitudinal axis X of the plier nose 130. The number of the concave teeth 133 is preferably three or more, which is preferable to ensure that the water seal plate is securely locked by the

lips

131, 132 of the tool pliers and is stable during the pulling-out process. For example, in one particular exemplary configuration shown in FIG. 3a, four teeth 133 are included, and the teeth 133 are generally rectangular in shape and are angled with respect to the longitudinal axis X. Specifically, the teeth 133 shown in FIG. 3a may be sized to be approximately 10mm in length and 1.5mm in width, with the teeth 133 being at an angle of approximately 150 to the longitudinal axis X.

Of course, the size of the protruding teeth 133 can be set according to actual needs as long as they can pass through the opening of the water sealing plate to be replaced. Moreover, the angle formed between the teeth 133 and the longitudinal axis X of the first clamp lip 131 can be selected as desired within a range greater than 0 ° and less than 180 °, such as preferably within a range of 90 ° to 150 °.

Further, the distance between two adjacent convex teeth 133 may be set to be the same as or multiple of the distance between two adjacent openings of the water sealing plate to be removed. In this way, the teeth 133 can fit into the corresponding apertures when the water seal plate is manipulated. Here, the distance between adjacent teeth/openings refers to the distance between two corresponding points of two adjacent teeth/openings along the longitudinal axis X of the forceps tip 130.

At least one groove 134 is formed on an inner surface of the second jaw lip 132 facing the first jaw lip 131. The number and shape of the grooves 134 can match the teeth 133 on the first jaw lip 131. For example, in the configuration specifically shown in fig. 3b, four recesses 134 are included which are sized slightly larger than the teeth 133 and are angled at an angle to the longitudinal axis X of the plier nose 130 equal to the angle of the teeth 133 to the longitudinal axis X. For example, in one illustrative example, the grooves 134 are 12mm in length and 2mm in width, and the grooves 134 are angled 150 ° from the longitudinal axis X of the plier nose 130.

In a modified construction, the recess 134 may be omitted. Specifically, the height of the protruding tooth 133 may be set to be greater than the thickness of the water seal plate, so that when the first lip 131 and the second lip 132 of the jaw 130 are closed, a gap sufficient to accommodate the water seal plate is generated between the first lip 131 and the second lip 132.

The method of pulling out the water sealing plate using the tool pliers 100 will be described with reference to the structure of the tool pliers 100 shown in the drawings.

First, the operator pulls the end of the water seal plate out of the coater either by hand or with a tool. The tool pliers 100 are then used to grip the water closure plate which has been partially pulled out, with the teeth 133 on the first lip 131 engaging corresponding openings in the water closure plate. And further, the teeth 133 also at least partially fit into corresponding grooves 134 formed on the second jaw lip 132. In this way, the operator can easily pull out the water seal plate from the coater, and the water seal plate is effectively prevented from slipping off the tool pliers 100 during the pulling-out process.

The foregoing discloses preferred embodiments of the clamping tool of the present invention. Obvious modifications to the invention, based on the preferred construction disclosed above, will be apparent to those skilled in the art and are within the scope of the invention.

For example, the jaw tool may take a form other than that of the tool holder 100, as long as it is a structure including two members movable toward and away from each other, in which the above-described convex teeth are formed on a surface of one member facing the other member. For example, the clamping tool may comprise two clamping plates connected by a resilient mechanism, such as a U-shaped leaf spring or the like, which biases the clamping plates away from each other. And when the operator exerts a force on the clamping plates that overcomes the resilient means, the clamping plates can be brought closer together. A convex tooth is formed on the surface of one of the two clamping plates facing the other.

Furthermore, although the above disclosure has been described with reference to a water seal plate for a pull-out coater, it will be appreciated that the clamping tool of the present invention may be used in other similar fields to clamp other types of sheet materials including holes.
